Abstract: Green development is an important support for high-quality urban economic growth, which requires the harmonious co-existence between humans and nature and the win-win of economy and ecology. In order to further analyze the connotation of green development, this paper introduces environmental resources as a special production factor into the dynamic general equilibrium framework, constructs an endogenous growth model including the final product department, environmental department, clean technology R&D department and other 4 departments, and deduces the equilibrium solution to realizing green development. Based on the panel data of 286 Chinese cities from 2003 to 2017, this paper empirically tests the necessity of green development in Chinese cities by constructing the simultaneous equations of material production function and pollution discharge function of the final product department. The results show that: firstly the higher the human capital investment of R&D department, the higher the production efficiency of R&D department and human resources department, the lower the time discount rate and risk preference of consumers—the higher the urban economic growth rate and the more conducive to green growth. Secondly, in order to realize the green development of co-prosperity between humans and nature, the growth rate of environmental resources stock must be greater than that of economy and consumption, and the repair and purification capacity of artificial environment will play an increasingly important role in green development. Thirdly, the input of traditional factors such as labor and material capital is still the main force driving the growth of China’s urban economic aggregate, and for every 1% increase in economic aggregate, pollution discharge will increase by more than 0.8%. The proportion of agricultural industry and industrial pollution industry increases urban environmental pollution with elastic coefficient values higher than 0.49 and 0.27 respectively. Environmental pollution restrains the economic growth of China and its western cities with the elasticity coefficient of more than 0.24. Environmental regulation has the effect of pollution reduction. In conclusion, it is necessary and urgent for Chinese cities to take the road of green development.
