人力资本、技术创新对环境污染的影响机制——基于全国285个城市的实证分析

基于2003~2016年中国285个城市数据，讨论了人力资本和技术创新对环境污染的影响机制。主要研究结论为：（1）人力资本和技术创新可以显著降低环境污染；（2）人力资本和技术创新对环境污染的影响存在协同作用，在人力资本的影响下，技术创新显现出明确的减污效应，同时在技术创新的影响下，人力资本也显现出明确的减污效应；（3）人力资本和技术创新跨越各自的门槛值后，二者的协同效应会增强，减污效果更明显；（4）人力资本和技术创新对环境污染的影响是通过“产业清洁效应”、“外资清洁效应”和“金融清洁效应”3类中介途径实现的。研究结论为我国环境污染的治理提供了有益的借鉴。

Research on the Influence Mechanism of Human Capital and Technological Innovation on Environmental Pollution： An Empirical Study Based on 285 Cities Across the Country

Based on data from 285 cities in China from 2003 to 2016，the impact mechanism of human capital and technological innovation on environmental pollution was discussed. The main research conclusions are as follows：（1）Human capital and technological innovation can significantly reduce environmental pollution；（2）Human capital and technological innovation have synergistic effects on environmental pollution. Under the influence of human capital，technological innovation shows a clear pollution reduction effect. Under the influence of technological innovation, human capital also shows a clear decontamination effect；（3）human capital and technological innovation cross the respective thresholds，the synergy effect of the two will be enhanced，and the pollution reduction effect will be more obvious；（4）human capital and technology The impact of innovation on environmental pollution is achieved through three types of intermediary channels：“industrial cleansing effect”，“foreign cleansing effect”and“financial cleansing effect”. The conclusions of this paper provide useful reference for the treatment of environmental pollution in China.
