*5.2. Identified Drivers for Human Capital Development and Consumer Behavior in Context of Industry 4.0 Revolution*

As Figure 4a shows, the analysis performed on the 111 studies, highlighted some key aspects for the development of human capital in the industry stage 4.0: information, new jobs, Internet, technology, training, education, new skills, automation, communication, innovativeness, professionals, productivity, artificial intelligence, digitalization, e-recruitment, and the Internet of Things. These factors contribute to the development of human capital in three directions, namely: (1) Reducing the number of jobs allocated to human labor; (2) Allocating a labor force to other areas that produce higher added value; (3) Increasing the demand for a labor force endowed with the skills required by new technologies.

Figure 4b displays the main drivers for consumer behavior in context of industy 4.0 revolution: Information, e-commerce, digitalization, Internet of Things, e-distribution, technology, automation, personalized, performance, artificial intelligence, behavior intention, e-shopping, and data mining. These driver factors contribute to consumer behavior reshaping from four perspectives, namely: (1) Business model innovation; (2) New market trends in which online commerce is becoming increasingly important; (3) Increasing access to information and the increased volume of data with which both consumers and producers are bombarded; (4) Increasing pressure from competitors.

The economic development of the last decades has depended on the competitive advantage created by the cheap and skilled workforce. In the digital age, this advantage has eroded because the workforce must be highly qualified and ready to develop new skills. The changes generated by the industry 4.0 revolution require the adoption of new business models, production processes, and new curriculums in academic programs.
