环境规制、技术创新与工业绿色水资源效率

Environmental Regulation,Technological Innovation and Industrial Green Water Resources Efficiency

  • 摘要: 引入脱钩弹性与低通滤波技术检验2002-2019年期间环境规制、技术创新与工业绿色全要素水资源效率之间的脱钩走向,进而采用VAR计量模型对其均衡演化关系分别进行了存在性检验、脉冲及方差解释。结果表明:环境规制、技术创新与工业绿色全要素水资源效率之间的脱钩弹性正向良性趋势转变,不过有别于传统Kuznets曲线的倒"U"型关系,尤其是在经过滤波剔除高频噪音的影响后,环境规制与工业绿色全要素水资源效率之间先后表现出了两次倒"U"型波动和一次震动调整时期变化,技术创新与工业绿色全要素水资源效率之间的倒"U"型波动存在,但相比于环境规制其具有相对滞后性;环境规制、技术创新与工业绿色全要素水资源效率之间虽然具有长期协整关系,但环境规制对技术创新的协整机制尚不显著,环境规制对工业绿色全要素水资源效率的影响效果要优于技术创新,其引发的正向激励效应更为明显,而在规制强度提升的趋势下,其绿色全要素水资源效率对技术创新的依赖度会逐渐提高,但是技术创新的驱动效应亟待提高;工业绿色全要素水资源效率对环境规制、技术创新的冲击响应短期内会出现相反方向的波动效应,但是长期来看两者的调控能够进一步释放工业绿色全要素水资源效率的提升潜力,关键是要缩短对规制政策消化的时间长度,以及促进技术创新跨过"规模投入陷阱"。

     

    Abstract: The decoupling trend between environmental regulation,technological innovation and the efficiency of industrial green total factor water resources is analyzed from 2002 to 2019 based on the decoupling elasticity and low-pass filtering technology,and then their equilibrium evolution relationships are tested from the aspects of existence verification,pulse and variance interpretation by VAR measurement model. The decoupling elasticity between environmental regulations,technological innovation and industrial green total factor water resource efficiency has a better development trend,but it is different from the inverted“U”relationship of the traditional Kuznets curve. Especially after filtering out the impact of high-frequency noise,environmental regulations and industrial green total factor water resource efficiency show two inverted“U”-shaped fluctuations and a period of vibration adjustment. Although there is an inverted“U”-shaped fluctuation between technological innovation and industrial green total factor water resource efficiency,it is relatively lagging compared to environmental regulations. There is a long-term co-integration relationship between environmental regulation,technological innovation and the efficiency of industrial green total factor water resources,but the co-integration mechanism of environmental regulation on technological innovation is not significant. The impact of environmental regulation on industrial green total factor water resource efficiency is better than that of technological innovation,and the positive incentive effect caused by it was more obvious. Moreover,under the trend of increasing regulatory intensity,the dependence of its green total factor water resource efficiency on technological innovation has gradually increased,but the driving effect of technological innovation should be improved. The impact of industrial green total factor water resource efficiency on environmental regulations and technological innovation will have a wavy effect in the opposite direction in the short term,but in the long run,their regulation can further release the improvement potential of industrial green total factor water resource efficiency. The key to achieving the above goal is to shorten the length of time for digesting regulatory policies and promote technological innovation to overcome the“scale investment trap”.
