| The green transformation of manufacturing industry is not only the key to maintain the core competitiveness of the economy,but also an important link to achieve carbon peak in 2030 and carbon neutrality in 2060.As a new industrial form of integrated development of manufacturing industry and service industry,the service-oriented manufacturing industry has become an important development trend of global manufacturing enterprises,and is also the key to accelerate the green transformation of the manufacturing industry.Made in China 2025 clearly puts forward the overall requirements for the green development of the manufacturing industry,as well as the strategic requirements for promoting the intelligent and service-oriented manufacturing industry in China,Make the manufacturing industry develop to the mode of “intelligent manufacturing+green manufacturing”.This paper takes the green transformation of manufacturing industry in the Yangtze River Economic Belt as the research object,and discusses the mechanism and path of manufacturing input service to accelerate the green transformation of manufacturing industry.First,according to the data of the input-output table of the Yangtze River Economic Belt,the total consumption coefficient of each region is calculated as the level of manufacturing input service,and the status quo of manufacturing input service level is analyzed from both industry and region aspects;Second,calculate green total factor productivity of manufacturing industry according to SBM-M index model,and analyze the status quo of green transformation of manufacturing industry from the overall and regional levels;Third,analyze the mechanism of manufacturing service input influencing the green transformation of manufacturing industry,and put forward research assumptions;Finally,a panel model is constructed to empirically analyze the direct and indirect mechanisms of the acceleration of green transformation of manufacturing inputs in the Yangtze River Economic Belt,and explore the heterogeneous impact of different regions and different service factor inputs on the green transformation of manufacturing.The results show that:(1)The overall service level of manufacturing input in the Yangtze River Economic Belt has shown a rising trend year by year,and there are differences between regions and different service factor input levels.The overall value of GTFP in the Yangtze River Economic Belt is obviously greater than 1.The overall green transformation of manufacturing industry in the Yangtze River Economic Belt shows a good development trend,and there are differences in the green transformation of manufacturing industry in the region,mainly reflected in that the downstream is superior to the upstream,and the upstream is superior to the midstream;(2)Whether it is direct investment or full investment,the level of service-oriented manufacturing investment has a significant positive impact on promoting the green transformation of the manufacturing industry,and has passed the robustness test;(3)From the perspective of the heterogeneous impact of manufacturing input service in different regions on green transformation of manufacturing industry,the impact of upstream and midstream input service on green transformation of manufacturing industry is weaker than that of downstream regions.From the perspective of the heterogeneity of different service input factors on the green transformation of manufacturing industry,information technology,finance and other service inputs play a more significant role in promoting the green transformation of manufacturing industry,while wholesale services and leasing business services have relatively weak effects on accelerating the green transformation of manufacturing industry;(4)It is found that the influence coefficients of structural optimization and technological innovation variables are significantly positive when the control variables and double fixed effects are added,and after the structural optimization and technological innovation variables are added,the significance of the impact of manufacturing input service on the green transformation of manufacturing industry decreases,indicating that manufacturing input service can promote the green transformation of manufacturing industry through the structural optimization effect and technological innovation effect.Based on the above research conclusions,this paper proposes to accelerate the green transformation of manufacturing industry in the Yangtze River Economic Belt from three aspects:improving the quality of input service,strengthening the innovation integration of service industry and manufacturing industry,promoting the coordinated development among regions in the Yangtze River Economic Belt,and continuously exerting the effects of technological innovation and structural optimization. |
