Effects Of Manufacturing Serviceization On Carbon Productivity Under Global Value Chains

Driven by the developed countries,trade liberalization and information technology have enabled different value links of commodities to be professionally divided and produced on a global scale.The global industrial value chain is gradually formed and continuously deepened.Although China has obtained a good opportunity to participate in the division of labor in the global value chain,it has been locked in the low-end link of the global value chain for a long time,and the added value of products that China’s manufacturing industry can obtain is relatively small.The rapid growth of the Chinese economy in the past cannot be separated from the development of the manufacturing industry.However,extensive development has brought great energy consumption and pollution emissions,and sustainable development is facing huge challenges.China is both a major trading country and a polluting country,and the existing manufacturing development model has become unsustainable.Faced with the reduction in value added due to lack of competitiveness and the increasingly obvious constraints on resources and ecological environment,how to achieve coordinated development of economic growth and environmental protection will be an urgent issue for China’s development.This thesis studies the relationship between manufacturing service and carbon productivity from theoretical and empirical levels.In theory,based on the perspective of the global value chain,through the improvement of the existing mathematical model,the derivation of the mathematical model has obtained the specific factors that affect the carbon productivity,mainly based on the degree of manufacturing service.Subsequently,this thesis demonstrates and analyzes the factors that affect the carbon productivity,such as the input and output of service factors,economies of scale,industrial structure,technological progress,and environmental regulations,which provide a theoretical basis for subsequent empirical regression.In terms of empirical aspects,first of all,this thesis firstly measures the manufacturing service level,and organizes and analyzes the data from the aspects of country,industry and factor density.Secondly,using single factor carbon productivity as an indicator,this thesis measures the carbon productivity of 14 manufacturing sectors in 41 countries and regions in the world from 1995 to 2014,and analyzes the development trend of carbon productivity from the national and industry levels.Finally,based on the derivation and calculation of mathematical models,this thesis builds an empirical analysis model of manufacturing service influencing carbon productivity.Analyze the impact of manufacturing service on carbon productivity from the overall sample,and analyze the impact of different types of manufacturing on carbon productivity by sub-sample regression analysis.Through threshold regression,verify the threshold effect of service level and environmental regulation level.According to the research,I have drawn the following conclusions: First,overall,the manufacturing service development of developed countries is better than that of developing countries,and the service level of manufacturing industries in developed countries is relatively high.In terms of factor intensity classification,technologyintensive manufacturing has the highest service level,while capital-intensive manufacturing and labor-intensive manufacturing are relatively low.Second,in general,the manufacturing carbon productivity of most developing countries is lower than that of developed countries,and the carbon productivity development of different industries varies greatly.However,in some specific manufacturing sectors,the gap between the carbon productivity of developing countries and developed countries is narrowing or even surpassing that of some developed countries.Third,in the overall sample regression results,this paper finds that the manufacturing service level can have a nonlinear effect on carbon productivity,and there is a "N" type development relationship between the two.In the regression of sub-samples,the service-intensive technology-intensive manufacturing has the most obvious effect on the improvement of carbon productivity,followed by labor-intensive manufacturing and capital-intensive manufacturing.The regression of manufacturing service level as the threshold variable shows that there is a double threshold for manufacturing service level,which confirms that the increase of manufacturing service level will have an impact on the rise,fall,and rise of carbon productivity.Regression results with the intensity of environmental regulation as the threshold variable believe that moderately strengthened environmental regulation can improve the carbon productivity of manufacturing,while stronger environmental regulation will inhibit the development of carbon productivity.Based on the perspective of the global value chain,this paper studies and analyzes the transformation and upgrading of manufacturing services,the status of the global value chain and the improvement of carbon productivity.It has certain enlightenment significance for China’s manufacturing industry to promote the division of labor in the global value chain through service-oriented transformation,increase the manufacturing carbon productivity,and realize the coordinated development of economic and environmental benefits.In order to achieve high-quality development,China’s manufacturing industry still needs to actively participate in the division of labor in the global value chain,continuously improve the service level of the manufacturing industry,encourage green R & D and the widespread investment and use of green technologies,and accurately formulate environmental policies that match the national economic development.
