Abstract
The application of green technologies can reduce environmental hazards and promote sustainability. The connotation of green technology innovation has two main aspects: the first aspect is the generation of green technology from nothing to something, and the other aspect is the improvement and upgrading of existing green technology; these two aspects are related. However, from the existing research, there are relatively few studies on the process of green technology innovation from these two aspects at the same time. If green technology is not studied from this perspective, the evolutionary process and influencing factors of green technology from generation to development cannot be clarified, which is not conducive to the development of green technology and the realization of the goal of environmental friendliness. Research considers the green innovation process from R&D to upgrading linkages and analyses the roles of government departments, green technology R&D institutions, and green technology application enterprises in green technology innovation. In addition, the green technology application enterprises are considered to promote technology enhancement through technology application feedback with green technology R&D institutions. The evolutionary game model of three subjects was established, the strategic evolution process of different subjects was analyzed, the influence of each element on the strategic choice of different subjects was explored, and the stability analysis of strategic choice was conducted using simulation software. The study shows the following: (1) The greater the government’s punishment and support to green technology R&D institutions, the more favorable it is for green technology R&D institutions to carry out green technology R&D. (2) In green technology applications, if the government has no direct interest relationship with green technology application enterprises, the enterprises will choose negative response behavior. (3) The greater the technology enhancement gains of green technology R&D institutions and the greater the feedback gains of technology applications actively carried out by enterprises in response to the government’s call, the more the government departments tend to support green technology R&D.
Highlights
Green technology is the basis of “green development”, which is a general term for technologies that aim at maximizing energy saving and environmental friendliness
A tripartite evolutionary game model of government departments, green technology R&D institutions, and green technology application enterprises is established from two perspectives of green technology R&D and green technology upgrading, and the equilibrium and stability of the interests of different subjects in the green technology innovation process and the influence of different factors on the subjects’ decisions are explored, and the model is verified using simulation software and the different subjects’ strategies
When ID1 + F < ID − RR, IT < P, and SS > SG, the expenditure of green technology R&D institutions not conducting technology R&D is smaller than the income obtained from conducting R&D, and the cost of feedback from enterprises is smaller than the benefit obtained from feedback from enterprises, and the loss of government departments not supporting conducting green technology R&D is higher than their input of supporting R&D. e evolutionary stability strategy is (0, 1, 1), the point means that green technology R&D institutions choose the strategy of not conducting technology R&D, companies choose the strategy of providing feedback on technology application, and the government chooses the strategy of supporting green technology R&D
Summary
Green technology is the basis of “green development”, which is a general term for technologies that aim at maximizing energy saving and environmental friendliness. A tripartite evolutionary game model of government departments, green technology R&D institutions, and green technology application enterprises is established from two perspectives of green technology R&D and green technology upgrading, and the equilibrium and stability of the interests of different subjects in the green technology innovation process and the influence of different factors on the subjects’ decisions are explored, and the model is verified using simulation software and the different subjects’ strategies. Based on the above assumptions, the Payoff matrix for R&D institutions of green technologies is shown in Tables 1 and 2
