摘要:

以绿色专利申请量为评价指标对长江经济带环境创新的时空特征进行了多维度挖掘,并揭示了其影响因素,研究发现:① 时序发展上,长江经济带环境创新空间集聚特征显著,绿色建筑技术始终主导长江经济带环境创新演化发展;② 空间演化上,长江经济带环境创新格局整体表现为由东部地区主导,并呈现出由东向西的阶梯推进的发展特征,且呈现出显著的空间关联性;③ 长江经济带环境创新具有显著的空间溢出效应,环境规制强度、技术创新水平、城市规模、第三产业比重和环境质量皆对长江经济带城市环境创新能力有着显著的正向促进作用,但环境规制强度不具有明显的空间溢出效应,且技术创新水平具有显著的负向溢出效应。

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
