环境规制对中国制造业技术创新的影响

Impact of Environmental Regulation on Manufacturing's Technology Innovation in China

基于行业异质性视角,以中国制造业20个细分产业2008—2013年的面板数据为样本,采用动态面板数据模型实证检验了环境规制对制造业技术创新的影响。研究结果表明:(1)环境规制与制造业的技术创新水平呈现显著的倒U型关系,拐点为0.4962;但具有产业异质性;(2)人力资本对制造业技术创新有正向影响,但受环境规制约束时降低了促进作用;(3)无论环境规制约束与否,外资参与程度对制造业不同产业的技术创新影响不同;(4)竞争程度对产业的技术创新水平有抑制作用。与此同时,制造业滞后一期的技术创新会受到上一期技术创新的影响。因而,政府在制定环境规制政策时要体现产业差异。

Based on the panel data of manufacturing industry in China from 2008 to 2013, this paper analyzed the influence of environ- mental regulation on technology innovation from the perspective of industrial heterogeneity by using dynamic panel data model. The re- sults show that： （1）There is a significant inverted-U shape relationship between environmental regulation and manufacturing＇s technology innovation in China, the inflection point is 0. 4962 ; but lies in different relationships in other industries on account of industry hetero- geneity; （2）The human capital has a positive impact on manufacturing technology innovation in China, but the promotion reduces when constrained by environmental regulation; （3）The impacts of foreign participation on manufacturing technology innovation in China are different whether constrained by environmental regulation or not ; （4）The degree of competition inhibits China＇s manufacturing technology innovation. Meanwhile, the current China＇s manufacturing technology innovation will be affected by that of previous. Finally, this paper puts forward specific suggestions to formulate the environmental regulations and policies differently as to different industries.
