长江经济带高技术制造业绿色发展效率研究

Research on Green Development Efficiency of High-techManufacturing Industry in the Yangtze River Economic Belt

基于2005~2019年全国30省份(不包括西藏、香港、澳门、台湾)高技术制造业相关数据,采用DEA方法测度30省份高技术制造业绿色发展效率,并进一步测算30省份环境规制强度,从全国、长江经济带上中下游地区、省域三类空间尺度研判高技术制造业绿色发展效率、环境规制强度、创新投资时空演变特征,重点分析长江经济带高技术制造业绿色发展进程中的比较优势和突出问题。研究结果表明:长江经济带高技术制造业绿色发展效率和环境规制强度均高于全国水平和长江经济带以外地区水平;上中下游地区绿色发展效率和环境规制强度存在显著差异;沿线11省份技术创新投资对环境规制成本的抑制作用不显著。应从三个方面进一步推动长江经济带高技术制造业绿色发展:一是因地制宜,精准施策;二是循序渐进,留下缓冲;三是强化创新,降低成本。

Based on the data of high-tech manufacturing industry in 30 provinces(excluding Tibet,Hong Kong,Macao and Taiwan)from 2005 to 2019,DEA method was used in this paper to measure the green development efficiency of high-tech manufacturing industry in 30 provinces,and to further measure the environmental regulation intensity of 30 provinces.The three spatial scales of the whole country,the upper,middle and lower reaches of the Yangtze River Economic Belt and the provinces were used to study the spatial and temporal evolution characteristics of green development efficiency,environmental regulation intensity and innovation investment of high-tech manufacturing industry,focusing on the comparative advantages and outstanding problems in the process of green development of high-tech manufacturing industry in the Yangtze River Economic Belt.The results show that the green development efficiency and environmental regulation intensity of the high-tech manufacturing industry in the Yangtze River Economic Belt are higher than the national level and the level of regions outside the Yangtze River Economic Belt.There are significant differences in green development efficiency and environmental regulation intensity in the upper,middle and lower reaches.The inhibitory effect of investment in technological innovation on the cost of environmental regulations is not significant in the 11 provinces along the route.We should further promote the green development of high-tech manufacturing industry in the Yangtze River Economic Belt from three aspects.Firstly,taking measures according to local conditions and adopting precise policies;Secondly,making progress step by step and leaving a buffer;Thirdly,strengthening innovation and reducing costs.
