A preliminary study on the relationship between environmental constraints, technological innovation and economic development in China - based on the development level and degree of coordination of the combined system

Under the theory of system synergy, this paper studies the development level and degree of coordination of the combined system of environmental constraint, technological innovation and economic development in China from 2011 to 2019. The results show that in recent years, the development level of China's technological innovation and economic development system shows an increasing trend year by year, and their trajectories are very similar, which indicates that China's economic development is increasingly driven by scientific and technological innovation. The trend for the environmental constraint level is more complicated and gradually became lower than that of the other two subsystems after 2016, which further leads to the slowdown of the growth of the degree of coordination of the complex system. The results show that the current ecological environment in China restricts economic development, and environmental protection and improvement is an important issue that cannot be ignored. Therefore, the government needs to further improve environmental regulation and use different tools to coordinate these improvements. Moreover, the most important thing is to establish a modernised development system based on green science and technology.
