环境规制强度与技术创新

随着环境污染日益严重，各界学者开始探索造成企业环境污染的因素，试图通过技术改进减少污染。尤其自1991年“波特假说”提出以来，越来越多的学者关注环境规制与企业技术创新的问题。以“波特假说”为理论背景，基于中国污染密集型制造业面板数据建立回归模型，以研发人员数量为控制变量，深入分析环境规制强度对我国污染密集型制造业技术创新的影响。结果发现，环境规制强度对污染密集型制造业的技术创新能力具有激励作用；在增加控制变量后，环境规制强度对于提高污染密集型制造业技术创新能力的影响更加显著。可见，“波特假说”适用于我国污染密集型制造业。最后，根据我国污染密集型制造业现状，提出地方政府环境规制和产业研发投入相关对策建议。

Environmental Regulation Intensity and Technological Innovation

As the environmental problem becomes more and more serious, the academic circles begin to pay attention to the effect of environmental protection on technological innovation.Especially since the Porter hypothesis was proposed in 1991, more and more scholars have been attracted to this issue.Based on the "Porter hypothesis" and taking the number of researchers as the control variable, this paper studies the effect of environmental regulations on technological innovation in pollution intensive manufacturing industries.The conclusion of this paper is that environmental regulation intensity has an incentive effect on the technological innovation ability of pollution intensive manufacturing industry.With the addition of control variables, environmental regulation intensity has a more significant incentive effect on the technological innovation ability of pollution intensive manufacturing industry.Thus, the “Porter hypothesis” is applicable to China's pollution intensive manufacturing industry.Finally, according to the current situation of pollution intensive manufacturing industry, this paper puts forward relevant policy Suggestions from the aspects of local government environmental regulation and industrial R&D investment.
