doi:10.13776/j.cnki.resourcesindustries.20211221.002

摘要/Abstract

摘要： 基于1998—2017年长江经济带11个省（直辖市）的面板数据，利用含有非期望产出的超效率DEA模型对各省（直辖市）绿色全要素生产率进行测度，运用相对价格的方差测算地区市场一体化程度，利用加入滞后一期绿色全要素生产率的动态空间杜宾模型进行回归分析。研究表明：1）1998—2017年长江经济带绿色全要素生产率变化整体呈“U”型趋势，2006年下降至最低点0.492。长江下游绿色全要素生产率最高，上游次之，中游最差。2）1998—2017年长江经济带各省（直辖市）一体化指数整体呈上升趋势,在2014年达到峰值，均值为1.527。长江经济带各省（直辖市）一体化变动趋势大致相同，历年长江经济带平均一体化指数为0.687。长江中游一体化程度最高，上游次之，下游最低。3）绿色全要素生产率具有较强的时间惯性和空间溢出性，区域一体化程度对地区绿色发展呈现出显著的先抑制后促进的“U”型关系，创新能力对长江经济带整体的绿色发展无显著影响，对长江中游地区影响显著；在区域一体化的背景下，创新能力能得到扩散，其交互项系数平均值为01，能对地区绿色发展起到促进作用。4）上游地区间创新合作是促进绿色发展的有效途径，中游地区区域一体化和创新能力结合给生态环境带来负效应，下游邻近地区一体化程度越高，绿色发展效率越差。各地区绿色发展具有很强的联系性，区域一体化水平达到一定程度后能对地区绿色发展起到促进作用，区域一体化和创新能力的结合能够促进长江经济带整体生态环境的改善。各地区应加强区域合作和创新，因地制宜制定政策，寻求有利于节能减排的创新技术合作，减少低效的创新投入。

Abstract: This paper uses super-efficient DEA model with non-expected output to measure green total factor productivity based on 1998-2017 panel data of 11 provinces in the Yangtze River Economic Belt, uses relative price variance to mark the market integration, and uses dynamic spatial Dubin model with one-stage-lagging green total factor productivity to conduct a regression analysis. The result shows that the green total factor productivity displays a U-shaped trend with the lowest value at 0.492 in 2006, and geographically, the upper-, down- and middle-reach are in a decreasing order. The integration index displays a spirally rising trend, up to the maximum of 1.527 in 2014, with an average value of 0.687 annually, highest in the middle-reach, followed by the upper-reach and then the down-reach. The green total factor productivity is of strong temporal inertia and spatial overflowing. Regional integration firstly constrains and then promotes the green development, while the innovation capability does little in the whole Yangtze River Economic Belt, but much in the middle-reach. Innovation capacity is expanding with an average mutual coefficient 0.1, promoting the green development under the setting of regional integration. Innovation cooperation is a pathway to green development in the upper-reach; a combination of regional integration and innovation capacity impacts ecological environment in the middle-reach; and the higher integration is, the lower green development efficiency is in the down-reach. This paper concludes that regional integration can boost green development after it reaches a certain level. A combination of regional integration and innovation capacity can improve the ecological environment in the Yangtze River Economic Belt. This paper presents suggestions intensifying regional cooperation and innovation, making appropriate policies, seeking innovative saving-energy-reducing-emission technical cooperation and decreasing low-efficient innovation input.

Key words: green total factor productivity, regional integration, innovation capacity, green development, the Yangtze River Economic Belt
