| The US CO2 Information Analysis Center(CDIAC)pointed out that China’s total carbon emissions rank first in the world.According to statistical data analysis,the contribution of my country’s industrial industry to GDP and carbon emissions in 2018 was 33.89%and 70.23%,respectively.The contribution of heavy polluting industries to GDP and carbon emissions in the industrial sector were 59.6%and 84.1%,respectively..How to make industries,especially heavy-polluting industries,achieve stable development under the constraints of energy conservation and emission reduction is the focus of practical and theoretical circles.First,this article uses the comprehensive intensity of the three wastes per unit of economic output to screen out 18 heavily polluting industries;secondly,using statistical analysis and other methods to analyze the evolution path of the carbon productivity of the heavily polluting industries over time;thirdly,drawing on panel data analysis technology,It analyzes the driving factors that affect carbon productivity and the path of environmental regulation that affects carbon productivity through technological innovation.The empirical findings:environmental regulations,technological innovation,enterprise scale,and industry.competitiveness all have a significant positive effect on the carbon productivity of 18 heavy polluting industries;energy consumption structure and industry profit margins have a significant negative effect on the carbon productivity of 18 heavy polluting industries;And the impact of environmental regulations on the carbon productivity of heavily polluting industries shows industry heterogeneity;10 industries including oil and gas extraction,ferrous metal mining and dressing,and non-metallic mining and dressing are in an inverted U-shaped curve.Rising stage;petroleum processing,coking and nuclear fuel processing,non-ferrous metal smelting and rolling processing industries are in the downward phase of the inverted"U" curve;6 industries including coal mining and washing,food manufacturing,beverage,alcohol and tea manufacturing are environmental regulations It has a linear relationship with carbon productivity;the test of the intermediary effect of technological innovation found that,in addition to the ferrous metal smelting and rolling processing industry and the ferrous metal mining and processing industry,in the other 16 heavily polluting industries,technological innovation is in the impact of environmental regulations on carbon productivity Both play an intermediary role.On the one hand,the research conclusions can provide theoretical support for the government to correctly use environmental regulation tools,formulate relevant policies,and ensure the healthy development of heavy-polluting industries on the basis of protecting the environment;on the other hand,it can encourage enterprises to respond to environmental regulations through technological innovation Restraint and enhance market competitiveness. |
