A Study On The Impact Of Technological Complexity Of China’s Production Service Imports On The Carbon Emission Of Manufacturing Industry

As early as 2007,China surpassed the United States to become the world’s largest carbon emitter.And China’s manufacturing industry,which has ranked first in the world in terms of value added for 12 consecutive years,has not yet changed its characteristics of high consumption and high emissions,and remains a key industry in terms of energy consumption and carbon emissions.And in 2020,President Xi Jinping announced at the75 th session of the United Nations General Assembly that China aims to reach peak carbon emissions by 2030 and achieve carbon neutrality by 2060.This goal points out the purpose of China’s low-carbon development in the coming decades and poses a challenge to put energy efficiency and emission reduction into practice.In this context,the decarbonization of the manufacturing sector is key to achieving the national decarbonization goal.To this end,the Chinese government has introduced various policies to promote the transformation and upgrading of the manufacturing sector and green development.One important channel is the deployment of high quality technology and talent.In particular,productive services,as intermediate inputs in the manufacturing industry,contain rich technical knowledge and human capital that can optimize production operations and play an indispensable role in achieving energy saving and emission reduction in the manufacturing industry.Therefore,this paper focuses on the significant value of exploring the impact of technical complexity of productive service imports on the carbon emission of China’s manufacturing industry.This paper explores the impact of import complexity of productive services on carbon emission of manufacturing industry from three dimensions: influence mechanism,measurement and current situation analysis,and panel data empirical evidence.Firstly,after collecting and sorting out the domestic and foreign research literature and related theories,we investigate the mechanism of the impact of the complexity of productive service import on the carbon emission of manufacturing industry in terms of the overall impact and the mechanism of human capital accumulation.Secondly,the data related to the complexity and carbon emissions and of imported technology of productive services are measured.Finally,the fixed-effects model and mediated-effects model are used for empirical evidence,and the impact of the complexity of productive service imports on carbon emissions in manufacturing industries and the influence path mediated by human capital accumulation are examined by separating high and low pollution industries and by industry heterogeneity.Through the above research,this paper draws the following conclusions: First,the complexity of importing productive services can significantly reduce the increase of carbon emission in manufacturing industry.Second,the import complexity of productive services can reduce the carbon emission of manufacturing industry by promoting human capital accumulation as a mechanism.Third,the increase in import complexity of productive services has a greater inhibitory effect on carbon emission in high-pollution manufacturing industries than in polluting manufacturing industries,and the mediating effect of human capital accumulation is more significant in high-pollution industries than in manufacturing industries as a whole.Based on the findings,this paper proposes the following suggestions to curb the carbon emission of manufacturing industry.First,take the initiative to expand imports and strive to improve the conditions for import trade liberalization and facilitation.Second,optimize and adjust the industrial structure of productive service imports and advocate the import of high technology complexity productive service industries;third,focus on accumulating human capital to open up a transmission path for the technical complexity of productive service imports to reduce the carbon emission of manufacturing industries,among which the role of human capital accumulation in reducing emissions in high pollution industries needs to be focused.
