Abstract:

The “T” structures in China’s territorial development and economic layout remain to be the two areas with the greatest potential for economic growth in China, among which the Yangtze River Economic Belt is the only first-class development axis across the three plates of East, Central and West. Over the years, in the excessive pursuit of rapid economic growth, the Yangtze River and its two sides of the great lakes and major tributaries have suffered serious environmental pollution, ecosystem imbalance, and frequent water security problems. To pay attention to the great protection together and not to engage in the great development is the guideline for the construction of the green Yangtze River Economic Belt, and the environmental innovation is the core support of the green development of the economic belt of the Yangtze River. In this paper, the spatial and temporal characteristics of environmental innovation in the Yangtze River Economic Belt are explored by taking the number of green patent applications as the evaluation index, and the influencing factors are also revealed. The results are as follows. First, from 2007 to 2017, the number of green patent applications in the Yangtze River Economic Belt increased from 35422 to 47563, among which the number of patent applications in the field of green building technology always ranked first. In addition, the environmental innovation of Yangtze River Economic Belt has significant spatial correlation effect. Second, in terms of spatial pattern, the environmental innovation of the Yangtze River Economic Belt was dominated by the eastern region, and shows the characteristics of development from the East to the West. Third, environmental innovation in the Yangtze River Economic Belt has significant spatial spillover effects. The intensity of environmental regulations, technological innovation level, city scale, the proportion of tertiary industry, and urban air quality all have a significant positive role in promoting the urban environmental innovation capacity of the Yangtze River Economic Belt. The intensity of environmental regulation does not have obvious spatial spillover effects, and the level of urban technological innovation has significant negative spillover effects.

Key words: environmental innovation, environmental regulation, green patent, spatial Durbin model, the Yangtze River Economic Belt
