1.1. Definitions and Context
Innovation is a core driver of national social development. It plays a key role in enhancing the competitive advantages of organizations [
1]. With global technological advancements and rapid industrial evolution, scientific and technological innovation has become the foundation of national economic competitiveness. Due to the development of economic globalization, the competition for innovation between different regions has evolved into competition between regional systems [
2]. Consequently, a series of regional innovation centers have emerged in different countries. In this context, improving regional innovation capabilities and designing scientific and efficient innovative development models play crucial roles in the current economic development of developed as well as developing countries.
Regional innovation refers to the process of generating new ideas, technologies, and practices within a specific geographic area, typically with the aim of fostering economic growth, competitiveness, and social development. It encompasses various factors of the regional ecosystem, such as research and development (R&D), entrepreneurship, collaboration between academia and industry, infrastructure, and supportive policies tailored to the particular regional characteristics.
In addition to collaboration, infrastructure plays a crucial role in enabling regional innovation. Access to physical infrastructure like transportation networks, communication technologies, and research facilities is essential for facilitating the exchange of ideas and knowledge. Shenzhen, China, provides an example of a region that has transformed from a manufacturing center into a leading innovation hub driven by its focus on technology, entrepreneurship, and government support [
3].
However, regional innovation also faces challenges. Access to funding for R&D and startup ventures can be limited in regions with fewer financial resources. Talent retention is another concern, as regions must compete to retain skilled workers and prevent a “brain drain” to more established innovation hubs. Moreover, effective policy coordination among government agencies, industry stakeholders, and educational institutions is essential to create an enabling environment for innovation [
4].
Overall, regional innovation is a multifaceted process involving collaboration, infrastructure, entrepreneurship, and supportive policies. By leveraging their unique strengths and addressing challenges, regions can enhance their competitiveness, spur economic growth, and improve quality of life [

1.2. Components of the Regional Innovation System
From the standpoint of innovation systems, a Regional Innovation System (RIS) is an open system made up of innovation resources (technology, knowledge, and information) [
8] and innovation actors (government, core businesses, universities, research institutes, and intermediaries) [
9,
10]. The innovation actors in a regional innovation system foster the diffusion, dissemination, and innovation of knowledge within the region [
10,
11] under the combined influence of innovation environments (i.e., market environment and social environment), thereby enhancing the evolution and efficiency of knowledge diffusion in the system.
Regional innovation systems are no longer limited by time or location in a digital context. Instead, they reorganize the current innovation resources and processes to create links and interactions across innovation actors, relying on digital technologies, knowledge-sharing platforms, crucial complementary resources, and knowledge-driven innovation.
Overall, the approach put forward in the literature and adopted by this paper views the RIS as comprising six subsystems, which include (i) a Subsystem of Capacity in Information and Communication Technologies (ICT), (ii) a Subsystem of Innovation and Regional Development; (iii) a Subsystem of Institutional Framework; (iv) a Subsystem of Knowledge Implementation/Capitalization; (v) a Subsystem of Knowledge Networking; and (vi) a Subsystem of Knowledge Production/Dissemination. These are briefly explained below.
The characteristics of a Regional Innovation System (RIS) pertaining to contemporary Information Technology (IT), its application, and people’s IT-related abilities are referred to as the Subsystem of Competence in ICT. By bringing individuals together who share interests, encouraging collaborative knowledge generation, and fostering the growth of intelligent learning environments, ICT facilitates the spread of information [
12].
The Innovation and Regional Development subsystem includes processes such as product innovation, process innovation, strategic intelligence, cooperative R&D, the emergence of new markets, the drawing of knowledge-intensive industries, and the production of spin-offs [
13].
The subsystem of the Institutional Framework focuses on the role of institutions in innovation. Inside an institutional framework, a variety of private and governmental organizations interact and function together. The traditions, customs, human value systems, and social structure of a nation are frequently referred to as the “institutional environment” or “institutional framework” [
13]. Particular laws and norms, as well as national and international regulations, make up the institutional framework at the regional level [
14].
In the subsystem of Knowledge Implementation/Capitalization, knowledge application and exploitation constitute a significant portion of RISs’ business operations. This subsystem’s primary constituents include clients, contractors, partners, and competitors [
15]. A dynamic regional innovation ecosystem revolves around creative enterprises and clusters that possess strong learning capacities and can convert their existing knowledge into commercial success [
16].
The Subsystem of Knowledge Networking refers to how supply chain relationships, firms, and networks of practices can create and/or spread knowledge through interaction [
17]. Knowledge can be categorized into explicit and tacit forms. “Explicit knowledge” refers to information that is documented, conveyed using formal languages, and stored in databases, archives, and libraries. Conversely, “tacit” information is difficult to formalize and convey through other human communication channels due to its individualized character. The accumulation of innovative activity is facilitated by tacit knowledge that is based on location [
5].
Finally, the subsystem of Knowledge Production/Dissemination is concerned with the sharing and transferring of knowledge through formal and informal practices. Knowledge transfer can be acquired through an established knowledge network, which is viewed as a network of connections between actors that facilitates learning between businesses and organizations [
18]. An economy’s knowledge base can be described as its capacity to generate and invent novel concepts, ideas, procedures, and goods, as well as how they might be interpreted in relation to economic growth [
19].
1.3. Literature Review and Research Aims
Regions play a crucial role in the global economy, being the first to experience the impact of economic changes and thus actively engage in the formulation of research and innovation policies [
13]. The Regional Innovation System (RIS) is a key tool for implementing these policies and analyzing the innovation process at the regional level. Since the early 1990s, the European Commission has introduced various policy programs that provide a strategic view of technology and innovation at the regional level [
20]. Programs such as the Regional Infrastructures and Strategies for Innovation and Technology Transfer (RITTS), Regional Technology Plans (RTPs), and Regional Innovation Strategies (RIS) have offered co-funding and guidance to regional governments. These programs aim to assess regional innovation potential and define strategies that promote cooperation and capacity building among small businesses, the research and technology community, and public authorities, ultimately achieving regional development [
21].
The issue of regional development in Greece has posed a consistent obstacle due to economic imbalances, unequal allocation of resources, and differing degrees of infrastructural development. To address these issues, European strategies such as Regional Innovation Strategies (RIS) and the Entrepreneurial Discovery Process (EDP) have played crucial roles [
22]. The Entrepreneurial Discovery Process (EDP) is an iterative process that involves stakeholders from various sectors to identify and exploit new opportunities for innovation and growth. EDP is a cornerstone of the smart specialization strategy, which aims to prioritize investments in key areas where regions have competitive advantages [
23]. These strategies are particularly evident in the regional policy frameworks and implementations, such as those seen in the region of Attica, Greece [
24].
The development strategy (2014–2020) includes Research and Innovation Strategies for Smart Specialization (RIS3). Based on the principles of the Europe 2020 strategy for smart, sustainable, and inclusive growth, RIS3 aims to achieve high levels of employment, productivity, and social cohesion within the EU and its Member States. Smart specialization is vital for sustainable growth, offering opportunities in both domestic and global markets. It also contributes to inclusive growth among regions, strengthens territorial cohesion, and manages structural changes, creating jobs and fostering social innovation [
22].
Additionally, the concept of Smart Cities has gained prominence. Globally, smart cities are seen as fundamental to the sustainable development of urban centers, ensuring their future expansion under sustainable conditions. Smart cities are part of the broader objective of Western societies, which is to transition towards a knowledge-based economy and society. These cities enhance human capacities for creativity, learning, and innovation. According to Komninos [
25], smart cities comprise three key components:
1. The innovation system (local/regional) of the reference region guides the development of knowledge and technologies within regional organizations (businesses, universities, technology centers, incubators, etc.).
2. Smart Technologies, including digital information and knowledge management applications that facilitate communication, decision-making, technology transfer, and collaboration in innovation.
3. The reference area, or the city itself, consists of the physical space and its inhabitants.
This research explores how the components of smart cities are linked at the regional level. The literature review identifies specific gaps, particularly in the complexity of policy planning and smart specialization, which involve multiple stakeholders and often insufficient information. Ranga and Etzkowitz [
26] highlighted the need for strengthened multi-level policies that require comprehensive evidence to identify and select regional priorities effectively [
27].
To address these gaps in strategy development, skills, and methods, the literature suggests leveraging Smart Technologies. Digital platforms are proposed as a solution, providing a dynamic economic structure that can enhance stakeholder engagement and the use of advanced datasets. These platforms enable the creation of ecosystems where users can collaborate across a wide range of activities [
28,
29,
30]. Such environments can be used for dissemination and sharing common goals, enhancing collaboration among stakeholders, and guiding innovation during the RIS3 design process [
25,
31].
Innovation, collaboration, and coordination can be effectively developed through network relationships [
32]. Consequently, online platforms in policy formulation and strategic planning should be considered key components of the Regional Innovation System [
25].
This research focuses on the use of New Technologies in Regional Innovation Systems for Regional Development. To this end, we will create a dynamic model capturing the level of Regional Development in relation to the contribution of smart technologies by the actors involved in the Regional Innovation System. This model will be applied to two Greek regions with different Regional Development indicators: the Region of Western Macedonia and the Region of Central Macedonia. It will serve as a guide and methodological tool for formulating appropriate regional policies by identifying strengths and weaknesses within the Regional System and enhancing those that provide multiplier benefits for Regional Development.
The research aims to answer whether the use of new technologies in a Regional Innovation System benefits Regional Development, as defined and measurable by specific indicators. The study focuses on modeling the influence of intelligent technologies on regional development, employing the RIS framework and utilizing the system dynamics technique. The objective is to examine the dynamic impacts of these technologies and offer a strategic analysis based on scenarios within two distinct Greek regions. Specifically, the study analyzed different possible values for:
The percentage of home Internet connections;
The presence of ICT specialists in the study region;
The usage of personal computers; and
The extent of ICT programs in the study area.
The model indirectly differentiates the values of the remaining independent variables.
1.4. Overview of the Study Regions
The mathematical model we present allows the empirical evaluation of the operation of a regional innovation system. The model developed is applied to the RISs of two Greek NUTS 2-level regions, Western and Central Macedonia, and various scenarios of changes in the indicators of smart technologies are developed to observe their impact on the two regions under consideration’s regional development.
The Region of Western Macedonia is located in the northwest of the country. It is the only region of Greece that is located far from the sea and is not on main tourist routes. It covers an area of 9451 km
2 and has a relatively small population of 250,453
1 (2023), which is decreasing due to immigration. The capital of the region is Kozani. The other much smaller population centers are Ptolemaida, Grevena, Florina and Kastoria. The region’s GDP per capita amounts to EUR 5.54926
2 million PPS (2022), representing only 60% of the EU average [
33].
Western Macedonia is a threatened region due to its high dependence on fossil fuel-related industry. For several decades, Western Macedonia was the main energy-producing region in Greece. Home to around 80% of Greece’s lignite industry, the region provided well over 70% of the country’s grid electricity at its peak—resulting in high CO
2 emissions and negative health impacts from associated air and water pollution. In the face of increasingly strict EU environmental directives, lignite power generation in the region has been phased out since 2010 [
34].
Economic decline and unemployment are the main socioeconomic challenges for the region. Unemployment rates in Western Macedonia hovered around 30% in 2012–2018 and have fallen to around 23% in recent years (16.7% in 2023
3) as people leave the region to find work elsewhere (Eurostat). Youth unemployment in the region is among the highest in the EU. It is estimated that over 20% of regional businesses have ceased operations since 2008, while the turnover of those that remain, particularly in the trade sector, has fallen by 40% [
35].
The region has a weak innovation potential, which is exacerbated by a strong outflow of people, especially among young people. There is almost no private R&D investment. The region’s other main sectors—fur industry and agri-food—are not traditionally knowledge-based. Overall, Western Macedonia—an emerging innovative actor according to the EU’s regional innovation scoreboard [
36]—currently does not present a fertile environment for innovation-driven growth [
37].
Western Macedonia is leveraging smart technologies to enhance public services, environmental management and energy efficiency. Urban areas implement smart city projects to improve mobility, waste management, and energy efficiency, which support the goals of sustainable and equitable urban development [
33,
38].
In addition, the region is exploring the application of digital technology in agriculture (precision farming), tourism (digital platforms to improve tourist experiences) and natural resource management. The aim is to utilize ICT to promote economic development, improve the quality of life and maintain environmental sustainability.
Central Macedonia, situated in northern Greece, encompasses the major urban center of Thessaloniki, as well as smaller cities such as Katerini and Serres. Its economy is characterized by diversity, with key sectors including industry, agriculture, tourism, and services [
39].
Central Macedonia is a modest innovator. Innovation performance has increased over time [
36]. Central Macedonia is a vibrant and diverse region located in the northern part of Greece. It is a focal point in terms of geography, economy, and culture. It is the second most populous region in Greece, and it includes the city of Thessaloniki, which is the second largest city in the country. Thessaloniki itself is a center of cultural activities, historical sites and educational institutions, making it a focal point for tourists and residents alike.
From an economic point of view, Central Macedonia is a power in the Greek context. It has a dynamic economy with diverse sectors such as agriculture, industry and services. The region is an important agricultural producer known for its fruits, vegetables and wine, thanks to its fertile plains. Industrial activity is also important, with an emphasis on areas such as food processing, textiles and heavy industry in the Thessaloniki area [
39].
The region boasts a robust industrial base, with manufacturing activities spanning textiles, food processing, chemicals, pharmaceuticals, and automotive sectors. Thessaloniki stands out as a major industrial and commercial hub, attracting businesses and fostering economic activity [
40].
Agriculture thrives in Central Macedonia due to its fertile land and favorable climate. The region produces grains, fruits, vegetables, olives, and tobacco, contributing significantly to its economy. Tourism is another vital sector, drawing visitors with its cultural heritage, historical sites, and scenic landscapes. Thessaloniki offers Byzantine monuments and a vibrant cultural scene, while coastal resorts along the Thermaic Gulf and Halkidiki peninsula attract beachgoers and tourists. Services play a crucial role, with Thessaloniki serving as a commercial and financial center, hosting businesses, banks, and service-oriented enterprises. The city’s port and transportation infrastructure facilitate trade and connectivity within the region and beyond.
Central Macedonia faces challenges like unemployment and the need for innovation. However, opportunities for growth exist, including further development of tourism, promotion of entrepreneurship, and leveraging its strategic location. In summary, Central Macedonia’s economy is diverse, supported by its industrial strength, agricultural resources, tourism appeal, and strategic location, positioning it as a significant contributor to Greece’s economic landscape [
