环境规制和R&D投入对实现绿色技术进步具有重要影响,但环境规制能否激励工业的R&D创新活动偏向于绿色技术研发尚缺乏深入研究。为此,本文采用基于SBM的Global Malmquist-Luenberger(GML)指数方法测算了1998-2012年中国30个省级层面工业部门的绿色技术进步,通过数理模型推导了环境规制对R&D投入向绿色技术研发偏向的促进作用,并采用动态面板的GMM方法进行了实证检验。研究结果表明:(1)总体上的R&D投入显著有利于工业的绿色技术进步,表明中国工业的自主创新符合新型工业化的发展要求;(2)单纯的环境规制对工业部门绿色技术进步的作用不显著,而通过引导R&D偏向绿色技术方向却是显著的,但是其偏向作用的有效时间只有当期和滞后1期,滞后2年的环境规制对工业研发的引导作用不显著;(3)由于环境规制存在挤占R&D投入的负面作用,导致整体上环境规制对工业部门绿色技术进步的正负影响相互抵消,从而表现为不显著。(4)国有产权、企业规模和对外开放均能够促进中国工业绿色技术进步,而地区工业污染排放强度不利于绿色技术水平的提高。
As a number of studies have confirmed, environmental regulation and R&D investment has an important influence on the green technological progress. The question is that as the main tool for government dealing with environmental issues, can environmental regulation guide China' s industrial R&D in favor of green technological research and development? In this paper, we estimate the green technological progress of 30 provinces in China' s industrial sector from 1998 to 2012 based on the SBM' s Global Malmquist- Luenberger (GML) index, and conducte the empirical testing by mathematical models and the dynamic panel GMM method. The results show that: (1)R&D investment significantly in favor of green technological progress on the whole, showing that innovation of Chinese industry consistent with the development requirements of new industrialization; (2)Environmental regulation has promoted R&D tend to green technological research and development, but the effective time of this promotion is only for current year and one year, lagging behind two years is not significant ; (3) Because of environmental regulation exists to squeeze the R&D investment, resulting in the overall that the positive and negative effects of environmental regulation on promoting green technological progress cancel each other, so as not significant; (4)The state-owned property rights, enterprise scale and opening to the outside world can promote the development of China' s industrial green technological progress, and regional industrial pollution emission intensity is not conducive to the improvement of the level of green technology.
