环境技术创新、产业间关联与工业环境绩效

Environmental Technology Innovation,Interindustry Correlation and Industrial Environmental Performance

环境技术创新是改善环境绩效、推动产业绿色化转型的重要途径,但是仍缺乏这方面的实证检验。基于中国2002—2012年投入产出表和手工收集的环境技术创新数据,实证检验了环境技术创新对工业企业环境绩效的影响。研究发现,环境技术创新通过直接效应和间接效应减少环境污染;基于供应链的产业间关联,上游行业的环境技术创新通过跨部门市场交易能够有效改善下游行业环境绩效;区域内产业环境技术创新和区域外环境技术创新作为改善环境绩效两个渠道具有同样重要作用。

environmental technology innovation is an important way to improve environmental performance and promote green industrial transformation, but there is no empirical test in this area. Based on the input-output table of China from 2002 to 2012 and the environmental technology innovation data collected by hand, this paper empirically examines the impact of environmental technology innovation on the environmental performance of industrial enterprises. It is found that environmental technology innovation reduces environmental pollution through direct and indirect effects. Based on the interindustry correlation of supply chain, the environmental technology innovation of the upstream industry can effectively improve the environmental performance of the downstream industry through cross-sector market transaction. Industrial environmental technology innovation within the region and environmental technology innovation outside the region play an equally important role as two channels to improve environmental performance.
