Research On The Impact Of Intermediate Input Of Producer Services On The Technology Content Of China’s Manufacturing Exports

The intensified competition in the global manufacturing industry and the complex and changeable political and economic environment have had a profound impact on the development of the global manufacturing industry.China has always participated in the division of labor in the global value chain by relying on its advantages in labor costs,and has formed a processing trade export model with low added value.At present,China is facing great changes unseen in a century,and my country’s manufacturing industry is in a critical period of transformation and upgrading in the face of fierce international competition.At the same time,with the improvement of economic development level and the deepening of marketization,the degree of integration of manufacturing and service industries has been further improved.The servitization of manufacturing is the development trend of the global industry,and the proportion of producer services in the overall service industry continues to increase,as the industry most closely related to manufacturing production,can not only break through the "lowend lock-in" situation in the global value chain,but also drive the transfer of highquality production factors between industries,and promote industrial transformation and upgrading;and improving the technological content of manufacturing exports is an important content and means of it.Therefore,the question that this paper intends to study is whether the intermediate input of producer services will promote the improvement of the technological content of manufacturing exports? and the mechanism of action? Due to the existence of industry differences,will different intermediate inputs of producer services have a differentiated impact?In view of the above problems,this paper firstly sorts out and summarizes the relevant literatures explaining the relationship between the two.In terms of internal mechanism,the technological content of manufacturing exports is improved through three specific mechanisms: technology promotion effect,human capital supplement effect,and cost reduction effect.Secondly,it makes a specific analysis of the structure of intermediate input in China’s producer services industry,and uses Ni Hongfu’s(2017)export technology content measurement method based on production process,and uses the 2000-2014 world input-output table in the WIOD 2016 and the supporting social and economic accounts database,the export technology content of 17 manufacturing industries in China is measured,including three indicators: total technology content,domestic technology content,and domestic technology content index.The measurement results are compared and analyzed in terms of industry,time,and international dimensions.Finally,a panel data model of the two is constructed,and the source and types of productive service input,and types of manufacturing industries are further distinguished,and an empirical study of heterogeneity is conducted.Through the above research,this paper draws four conclusions: from the perspective of the whole sample,the intermediate input of producer services industry can significantly improve the technological content of manufacturing exports.Under the condition of distinguishing input sources,service types and factor-intensive types of manufacturing,we further find that the impact of differentiation mainly includes: Firstly,both domestic and imported foreign producer services input both can promote the improvement of the technical content of my country’s manufacturing exports,and the positive impact of domestic producer services intermediate inputs is greater;Secondly,the five types of productive service industries,wholesale and retail services,transportation,warehousing and postal services,telecommunications and information services,financial services,and business services,can significantly improve the technological content of manufacturing exports,R&D,design and technical services have no significant impact;Finally,the intermediate input of producer service industries has the greatest effect on improving the technological content of labor-intensive manufacturing exports,while the positive impact on capital-and technology-intensive manufacturing decreases in turn.Based on the above theoretical,status quo and empirical research,combined with the background of China’s high-quality development,this paper finally puts forward three policy suggestions: Firstly,reasonably expand the liberalization of producer service trade,but at the same time control the order and degree of opening up of the producer service sector;Secondly,actively guide the local producer service industry to develop in a diversified and high-quality direction,especially to promote the role of advanced service industries such as technology services in manufacturing innovation;Thirdly,implement diversified export technology upgrade measures for different types of manufacturing industries to promote the absorption,transformation and application of productive services by manufacturing enterprises.
