This section presents the case of the long-lasting success of innovation in Silicon Valley, which has resulted from a profound process of interaction between creative elements. Then, this section discusses the case of the successive failures of Brazilian innovation, where public policies and growing investments have resulted in decreasing market novelties and lower quality of education. Finally, this section shows the example of technology clusters and incubators as a kind of intermediary solution, where bottom-up and top-down initiatives can go hand in hand to develop innovation. The idea is to depict the model using cases to illustrate it in different forms: when the actors’ free interaction results in robust innovation, in the first case; when public policies do not achieve good outcomes, in the second case; and how technology clusters could work as examples of successful integration of processes coming from opposite levels of the system hierarchy.
4.1. Silicon Valley, California
Studies have tried to understand the development of Silicon Valley’s industry and how innovation is so strong in this region. Some superficial opinions have talked about its sudden rise during the 1960s despite its lack of prior industrial history. However, this is not the case. The work from Sturgeon [
1] traces the movement back since before World War I, when the radio industry began in the San Francisco Bay Area, with its successors unfolding in telegraphy, electronics, television, and military products. For sure, this kind of development was also happening elsewhere in the country, but the Bay Area had cultural aspects that fertilized decades of continuous innovation in a very broad range. Sturgeon emphasizes its environment of creation, where elements (individuals and firms) move freely in their spaces, provoking movement and agitation, which grows as time goes by [
1]. Elements interact with each other loosely and, from this interaction, information and knowledge flowed (and flow) freely, with no control. Inventions have commercial protection (by patents), and rights are respected. Cooperative relations are a common sense rule. All these characteristics are adherent to the complex system theory, shown in the previous section. Sturgeon observes that cooperative relations between elements create dense groups that unfold in new groups (spin-offs). These new groups grow again, and relations are maintained between groups and subgroups. Here is a clear connection to the theory of Granovetter’s “strength of weak ties” concept [
13], when bridges link groups despite the fact that sometimes these groups are competing firms. These interactions allow new ideas, creativity, and innovation, because the interaction is open in the sense that no barriers disturb the interchange of ideas. When discussing Silicon Valley’s long-lasting success, Sturgeon says that the best results in innovation come when three skills are wedded: “practical mechanical brilliance”, “advanced technical training”, and “theoretical knowledge”. These skills need time and persistence to be acquired, and they can be in talented individuals or groups of individuals interacting. As we can see, the complex system’s keywords are repeating themselves here: elements; interaction; and no central control.
Kenney and von Burg [
2] talk about the creation and growth of Silicon Valley in terms of path dependency, as the concept was defined by Arthur [
9]. For them, innovation is a non-deterministic process; it is path-dependent. They argue that paths are a creation of human actors when interacting over time, and path dependency is intimately related to path creation. Decisions in a moment of history will reverberate through certain paths, closing some of them, validating others or even just one path. The validation of a path is not necessarily a rational process, and path dependence accepts the fact that even small events can have large effects and impacts. Social constructions and strategic maneuvering are critical for these paths when the environment is non-deterministic [
2]. Kenney and von Burg argue that technological advance is the result of the interaction of path-dependent processes, which are in these cases the actions of actors—individuals creating and reshaping the nature of institutions and organizations. That is, technological advance is a result of a culture of creation not of just a policy. They use as examples the tech industries in Silicon Valley, such as Hewlett Packard (founded in the 1930s), IBM, Ampex, Xerox, and many others since the 1940s and 1950s, just to cite a few. Kenney and von Burg consider Silicon Valley’s success to be the result of two interrelated economies: one that includes several firms of hardware and software of all dimensions and also universities; and another that includes companies of venture capital, specialized lawyers, consultants, and accountants [
2]. When discussing the first group, they found that a dense block of semiconductor firms created conditions for even more semiconductor firms. Why? The turbulence that comes from inter-firm and intra-firm relations opens space for the emergence of new products, new ideas, and, sometimes, entire new industrial categories. Spin-offs appear when a new idea is blocked internally in a company. But for a spin-off to be launched there must be an ecosystem that nurtures this new type of firm. Then, the interaction between firms and economies is the keyword for innovation [
2].
The work of Saxenian [
3] compares the evolution of innovation in Silicon Valley and in the Route 128 beltway around Boston, Massachusetts, because, despite the apparent similarities between both regions, they had divergent performance over the same period of time. From this study, several findings arise to confirm innovation as a typical adaptive system. Similar firms concentrated in a specific region gain the benefits of self-reinforcement through a dynamic process of increasing returns, which is a concept defined by Arthur [
9]. Companies in Silicon Valley compete intensely among themselves, but, nevertheless, there is an informal environment of communication and collaboration; that is, despite the competition, the relationships are strong, and information flows freely, horizontally. Boundaries between firms, universities, and institutions are porous [
3], describing an environment where bridges shape weak ties between them (Granovetter, [
13]). On the other hand, the Route 128 companies persist in secrecy and corporate loyalty, where information flows vertically inside them. Here, there are no bridges; groups and subgroups are closed and internally connected. Saxenian also found that the high performance of Silicon Valley cannot be attributed to the differences in costs, taxes, or wages. The most strategic relationships are local and face-to-face, because high technology is fast-changing, uncertain, and complex. Therefore, it depends on individuals’ relationships, even exchanging information through competing firms. The local culture of Silicon Valley institutionalized practices of informal cooperation and exchange and from this came a process of collective learning in the region. On the other hand, Route 128 was risk-averse and committed to formality, institutional hierarchy, and long-term stability [
3]. The Route 128 environment discouraged free relationships and thereby, continuous learning.
When studying the continuous success of Silicon Valley, Zhang [
4] found the same as Kenney and von Burg [
2]: this success comes from the constant emergence of successful start-ups, where the venture capital and high-tech industries grew and matured together, side by side as “two economies” strongly intertwined. Analyzing several cases of new companies, Zhang noticed that the founders of new start-ups were employees of incumbent firms, which shows the phenomenon of emergence coming from the interactions of individuals in a hierarchical system; that is to say, elements in one level interact and then come up to create a group at the next, higher level. Another interesting major finding of the study is that state and local government policies had a minor role in the early years of the growth of Silicon Valley, and its evolution is due to the culture of innovative thinking and industry–university networks, reinforced by a free flow of information between peers and even by competing firms [
4]. Finally, it is noteworthy in the study that quality of life is also a prominent factor in high-tech start-ups, because the founders launch their businesses in the locales where they would like to live. This means that a favorable place in which the elements interact, in a very broad sense, comes from the cultural view, not just from the restrictive theme of technology.
Summing up, the success of Silicon Valley demonstrates the continuous interaction of individuals and firms for decades, free of moorings despite the strong competition among them, where new start-ups come from incumbent firms, and this fact does not create conflict, but by the contrary, benefits the game of innovation. Innovation covers a very extended range of areas, from electronic to software, from retail to tourism services, from entertainment to the Internet-of-Things, and the list does not stop because one cannot know where the next step will take place.
4.2. The Brazilian Innovation Case
Considering the consistent success of Silicon Valley throughout the years, several countries, institutions, and individuals have paid attention to what was happening there, and some have tried to mimic it. Sure, some countries or regions have their own ways of pursuing innovation and are not looking to what happens in California, but others, especially developing countries, understand that they could learn good lessons from Silicon Valley, bringing and adapting initiatives and policies to accelerate their own innovation systems. Brazil, a country in Latin America with more than 200 million people as of 2017, is one such example, and the Brazilian innovation case is what we discuss in this subsection.
Since the 1980s, several Brazilian government initiatives and public policies have arisen with this purpose: innovation. Despite the fact that this text has no intention to list all them nor to analyze them, we mention a few emblematic and very distinctive policies to build a basis for the discussion that follows.
One important initiative in Brazil was the creation of tech incubators in the surroundings of public federal universities in the 1980s. These incubators were launched in the north, northeast, south, and southeast of Brazil, aiming to foster new innovative companies. Another government policy is to give subsidies to hardware companies. In the education sector, which has been dominated by public universities since the beginning of higher education in Brazil, rules and indicators for faculty members were established by the Ministry of Education, indicators such as the number of publications and number of citations that are fundamental for job promotion. These rules were followed by new rules and more funding for tertiary education, and this process of strict regulation finds no end (because the outcomes are not reaching expectations, as we will see below). The government’s contracts with the information technology sector were another initiative focused on the development of high-tech companies (the result was the growing of reseller companies, not necessarily developers). The theme of innovation took so much importance in Brazil during the 2000s and after that a ministry even added the word to its name—Ministry of Science, Technology, Innovation and Communications—compounding a mixed name as if this could impact favorably the innovation process.
However, as said above, the intention of this text is not to do a survey or list or to discuss these initiatives. The idea here is to verify the results of the Global Innovation Index [
15], where Brazil consistently appears in a very low position, decreasing in the ranking yearly (
Table 1 illustrates the top 10 countries compared to Brazil and other countries of South America, from 2012 to 2017). The Global Innovation Index is an independent institution, which provides an index of innovation, creating metrics to analyze the innovation performance of countries. This index began in 2007 and has changed over the years as the concept and indicators grew, until its consolidation in 2012/2013, including themes like political and business environment, education, infrastructure, and so on (the complete list and information about the index are in [
15]). The institution says that some indicators are quantitative, and others are qualitative; and they are not intended to be authoritative, just relative. The index has been gathering information on a varying group of around 125–145 countries over the years, and two of its partners are the National Confederation of Industry Brazil (CNI) [
16] and the Brazilian Service of Support to Micro and Small Enterprises (Sebrae) [
17], which are major public forces in Brazilian innovation development, linked or not to the Ministry of Science, Technology, Innovation and Communications (MCTIC) [
18].
So, considering the Brazilian ranking year by year, what happens in this country and why is innovation so poor despite government efforts? Why does innovation struggle and why does it not grow despite the public investments? To shed light on the problem, we could look at the Global Innovation Index indicators (from 2012 to 2017) and rearrange them to see how indicators related to each other and how public policies, on the one hand, and elements’ interaction, on the other hand, are the basis for the corresponding indicators.
The first comparison is pictured in
Figure 2, which shows three indicators. First, business environment, which reflects the “ease of starting a business, ease of resolving insolvency and ease of paying taxes” [
15]. Second, the growth of gross domestic product (GDP) per person engaged, which “provides a measure of labor productivity (defined as output per unit of labor input)” [
15]. Third, public expenditure on education per pupil in the secondary level, which is, “government spending on education divided by the total number of secondary students, as a percentage of GDP per capita” [
15].
The public expenditure on education is clearly a government policy, and the Brazilian ranking is growing slowly year by year. This is a top-down initiative with relative success when we relate it to labor productivity. Labor productivity, which depends on the individuals involved in their jobs and related processes, is falling very quickly when compared to other countries, as the indicator shows. Workers do not find ways to develop better or creative solutions to perform their jobs. Perhaps, the business environment is not propitious for good performance, and that is what the other indicator shows. Considered one of the worst business environments in the world, the Brazilian business environment is a result of all kinds of difficulties posted contradictorily by the same government that pursues innovation. Elements cannot interact freely, because rules, taxes, and other issues stifle the environment, despite the individuals’ levels of education or the efforts spent by them.
Figure 3 shows a comparison between three other indicators. First, expenditure on education is defined by the “government operating expenditures in education, including wages and salaries and excluding capital investments in buildings and equipment, as a percentage of gross domestic product” (GDP) [
15]. Second, graduates in science and engineering reflect “the share of all tertiary graduates in science, manufacturing, engineering, and construction over all tertiary graduates”. Third, the intellectual property payments, which are “charges for the use of intellectual property not included elsewhere payments (% of total trade) according to the Extended Balance of Payments Services Classification EBOPS 2010” [
15]. What we apprehend from this graph is that the Brazilian government continually expands its expenditure in education, and thus its ranking is improving, which apparently means good news. However, the number of graduates in sciences and engineering does not grow and, worst of all, intellectual charges are increasing because new technologies must be imported. The country is ranked in the top ten for paying for intellectual property and has a very low ranking position when talking about new engineers and scientists. Individuals prefer professions that are more rewarding and attractive, reflecting a process of evolution of elements in a culture and environment that do not favors science nor engineering.
The Brazilian ranking position for the indicators of gross expenditure in research and development, research collaboration between university and industry, and scientific and technical publications are shown in
Figure 4. The gross expenditure on “R&D (GERD)” means the “total domestic intramural expenditure on R&D during a given period as a percentage of GDP”. Scientific and technical publications are the “number of scientific and technical journal articles (per billion PPP
$ GDP - purchasing power parity)”. University/industry research collaboration is given by the “average answer to the survey question: in your country, to what extent do people collaborate and share ideas in between companies and universities/research institutions?” [
15]. What we see is that publications have a stable middle position and that the expenditure in research is also stable and has a better position in the ranking. However, the perception of collaboration between industry and university is decreasing yearly. While the expenditure in research in Brazil, roughly speaking, is a matter of public funding—that is, a public policy—the attitude of collaboration is a phenomenon that depends on the interaction between the actors specified. On the other hand, the number of publications is mainly an outcome of a policy that charges faculty results by a national periodic process of assessment. This rule forces faculty to publish as many articles as possible, and in a process of survival and evolution, the natural effect is publications with several co-authors, crossing citations, and little or no relation with the industry needs, because this demands time and no clear rewards for the academic researchers.
A direct output of the weak relationship between industry and university, despite the good number of publications in Brazil, is shown in
Figure 5: there is a good index of citations but a very weak knowledge impact index.
Figure 5 shows the indicator of citable documents related to the H index, which is “an economy’s number of published articles (H) that have received at least H citations in the period 1996–2014” [
15], and the knowledge impact (i.e., the outputs of knowledge and technology in the society). What the chart shows is somewhat of a paradox. How can a number of documents be well-cited, but this does not impact favorably the society where these documents were produced? Worst, the knowledge impact is decreasing yearly. An answer here could be that the public policy favors a high number of citations. The Brazilian govern created a system to assess courses, programs, and institutions based on the number of publications and citations in qualified magazines, journals, and newspapers. The belief that underlies this policy is that by favoring publications, an impact on knowledge will follow naturally. As the country is huge, with a large number of professors, it has created its own ecosystem of publications and its own process of assessment and scores, which benefit its own members (the official assessment platform is called Sucupira [
19]). Several years of this policy has created a closed circuit of cross-citations with several authors for each paper, published in journals referenced at the Qualis Capes [
19], resulting in a good ranking in the Global Innovation Index. Nonetheless, the knowledge impact of all this research production falls in a low ranking. Despite the public policy, the elements in this research ecosystem are forced by an obvious sense of survival, publishing as much as possible but detached from the society’s interests.
Looking to another aspect, the innovation index also shows some results regarding applied science and how the country relates to technology consumption.
Figure 6 illustrates three indexes for intellectual property payments, high-tech imports, and technology services export. Intellectual property payments are the “charges for the use of intellectual property not included elsewhere payments (% of total trade) according to the Extended Balance of Payments Services Classification EBOPS 2010”, which is how much the country pays to use intellectual property from abroad. The high-tech imports’ indicator is given by “high-technology imports minus re-imports (% of total trade)”. Technology services export is the “telecommunications, computer and information services (% of total trade) according to the Extended Balance of Payments Services Classification EBOPS 2010” [
15]. Companies and individuals from Brazil are intensive consumers of technology. From the companies’ points of view, technology is bought to be resold inside the country or to use in their internal processes. From the individuals’ points of view, it is a way to be up-to-date with several gadgets, from mobile phones to game stations and from television devices to social networks. In the same way that it imports high-tech products, the country is also a great importer of knowledge (paying for intellectual property). Both movements are dependent on the elements not on public policies, and this implies in a heavy dependency on external knowledge and technology—that is, low level of internal innovation combined with the weakness of research (as shown in the previous charts). Even regarding the export of services related to telecommunications, computer, and information, an index that is increasing slightly each year, the ranking position is poor.
A society immersed in the age of the internet is a reflex of modernity, some say, and Brazil follows this trend.
Figure 7 shows two indexes about this and its impact on innovation, accordingly to the Global Index of Innovation. One index is the online e-participation, which is “based on the survey used for the UN Online Service Index” for e-participation, and the survey emphasizes “quality in the connected presence stage of e-government”; the other is the Wikipedia monthly edits, defined by “Wikipedia yearly page edits (per million population 15–69 years old)” [
15]. The regular and good position of online e-participation reflects the involvement of Brazilians in the age of the internet, using regularly its services and applications, especially social networks and government services. On the other side is the weakness of content production; the creation of text, edits, and posts on Wikipedia denote the behavior of a consumer, not a producer of knowledge. This does not depend on public policies. Is it a question of culture?
In summary, the indexes presented for the Brazilian case seem to demonstrate a combination of problems that causes its poor position in the global ranking. Public policies try to stimulate and foster innovation in a top-down process, but the results return in the opposite direction. Movements that arise from the bottom—that is, the interaction of actors trying to launch new companies or to create relationships between university and industry—are suffocated by several restrictions imposed by other government policies (such as taxes, bureaucracy, restrictions, and so on). If innovation is path-dependent, any restrictions or barriers in the hierarchical process will affect or even destroy it. Years or decades of this kind of reality created an ecosystem that favors consumption more than creation, and the inherent evolution process rewards the ones that take advantage of this consuming condition, no matter how many new policies are implemented over time (as
Table 1 shows year after year). Despite the poor indicators presented in the Global Innovation Index and even after years of investment on public policies precisely done to boost innovation, the Brazilian government and its institutions keep launching more and more policies to induce it, trying to “prioritize the social impact of knowledge and technology engendered” [
20].
4.3. Technology Clusters
One initiative that has been connecting the elements from the lower levels of the market innovation system with the upper levels’ policies is the concept of technological clusters, with their incubators to foster technological novelties and start-ups. As defined by Petruzzelli, Albino, and Carbonara [
21], a technology cluster is constituted by the technology district’s actors in a geographically defined region, connected with external actors by means of organizational and cognitive proximities. Geographical boundaries define the region of the district as a dimension of the cluster, whereas the organizational links (such as the branches of a multinational company) and the cognitive links (such as similar interests and areas of research) define the other two dimensions. The authors emphasize several characteristics of these clusters that fit the complex adaptive systems theory, particularly the model we have presented. They consider that these clusters favor the process of learning by imitation and learning by interaction “based on the continuous exchange of information and knowledge among complementary firms, among firms and customers, and among firms and universities/research centres” [
21]. These interactions clearly describe the communication between elements in several levels of the innovation system. These interactions may be face-to-face when the elements are within a region, but knowledge also can “circulate through global pipelines” when the cognitive and organizational proximity dimensions are present, and then “radical innovations” can be developed, characterizing the path dependency of these innovations. Clusters can create connections, and then, “weak ties” [
13] between these clusters will favor free interaction, because these ties happen in the middle of “loosely coupled networks”, deriving “positive effects on both connectivity and receptivity caused by a variety of communication channels” [
21]. When studying knowledge sources for technology clusters, Petruzzelli, Albino, and Carbonara [
22] emphasized the importance of networks in innovation, because “individual actors are seldom capable of innovating independently, and never in vacuum”, and the networks “greatly enhance the processes of knowledge creation and diffusion”. The technology clusters cited in their studies are the Castel Romano, in the province of Roma, Italy, specialized in the aviation and military industries, and the technology district of Toulouse, France, specialized in the aviation and aerospace industry [
22].
Cluster initiatives have been important issues for regional development, competitiveness, and innovativeness. Several actors, such as firms, universities, research institutions, agencies for regional development, associations, local government, and other cooperating entities, work together for the cluster growth. Considering knowledge flow to be crucial for innovation development, Dyba [
23] analyzed how knowledge flows from entrepreneurs to market upper levels (bottom-up processes) and how public policies can affect knowledge spillover (top-down processes). The author studied two cluster initiatives that had different approaches in the very beginning: the Swarzędz Cluster of Furniture Producers, launched by local entrepreneurs, and the Leszno Flavours Food Cluster, created by the municipality authorities. From his findings, the author suggests that knowledge flow depends on the origins of the cluster; that is, when the cluster is a top-down initiative, knowledge spillover mainly occurs between entities in the upper levels, such as universities, institutions, and research centers. On the other hand, firms and individuals are mainly responsible for these flows in clusters created formally or informally by these very basic elements of the ecosystem [
23]. These conclusions seem to agree with the Brazilian and Silicon Valley cases, respectively.
Most of the technology clusters were the result of arrangements between firm associations on one side, and public policies from local authorities on the other, with more or less emphasis on each side. The questions that arises is: will top-down public policies affect innovation positively? One answer comes from Petruzzelli, Albino, and Carbonara [
22] suggesting that “local governments should address their actions to help and promote the openness of technology districts and the formation of technology clusters”, by sustaining local firms, increasing competition, and fostering the diffusion and sharing of knowledge. As in the words of Arthur [
9], government policies should just favor structures that could emerge naturally and not try to coerce an innovation outcome.
