The Mechanism And Empirical Study On Productive Service Industry Promoting The Upgrading Of Domestic Value Chain

In the context of China's external international market is relatively shrinking,the demand for orders is relatively reduced,the status of international foundry has been challenged,domestic wage costs have risen,raw material prices have risen,and industrial upgrading has been faced with a dilemma,the domestic value chain,which is based on domestic demand,has independent research and development innovation ability and brand sales terminal,and is connected with the global value chain,is an effective way to realize industrial upgrading and regional coordinated development in line with China's national conditions.Through the analysis of value chain,many scholars have found that productive services play a key role in the development of a country's economy and the upgrading of domestic value chain.How to use productive services to reconstruct domestic value chain and realize the upgrading of domestic value chain is an urgent problem to be solved in our country.Based on the current situation of domestic value chain,this paper uses quantitative analysis method,combining vertical professionalization index,regional upstream index and regional factor endowment to measure the embedding degree,depth and matching degree of domestic value chain in each region,and finds that the participation level of China's domestic value chain shows that gradient pattern is "inland is higher than the coastal,middle and west than the east",the eastern coastal areas are closer to the middle of the production chain than the central and western regions,the value chain is not perfect,the professional level is low,and most areas still exist some degree of resource allocation distortion.In addition,in the process of upgrading the domestic value chain,there are many obstacles,such as local protectionism,public goods differences,property rights system,lack of key resources,excessive competition and cultural ideas.Based on the analysis of the status situation of the domestic value chain and the upgrading of the dilemma,this paper makes a theoretical and empirical analysis of the promotion mechanism of the domestic value chain from the industrial level and the regional level to the producer service industry.In the aspect of theoretical analysis,this paper combines the existing research results,on the one hand,based on the industrial point of view,from the service outsourcing to deepen the value chain division of labor,gaining access to specialized services,gathering scale effect and knowledge integration effect,industrial integration spillover effect as well as the relevant theoretical model to derive and analyze the role of producer services in promoting the growth of the manufacturing value chain and thus promoting the upgrading of the domestic value chain.On the other hand,based on the regional perspective,from the production services industry to provide information and transport support to promote the regional industrial chain of industry and technology chain network,to promote the formation of leading enterprises in the region and the formation of specialized market,from these aspects to analysis the role of the productive services in improving the participation of the regional value chain in the region and promoting the upgrading of the domestic value chain.In the aspect of empirical test,based on the industrial point of view,this paper chooses the data of the eastern region from 2004 to 2015 to establish the panel data model,and verify the role of the producer service industry in promoting the upgrading of the manufacturing value chain to promote the upgrading of the domestic value chain from a multidimensional perspective.On the other hand,based on the regional perspective,this paper takes 31 regional regions in 2012 and 22 industrial sectors in the eight provinces in 2002 and 2007 as the research objects,establishes the cross-sectional data model,tests the productive services,by region,sub-industry,and time trend,as the role of professional development in raising the level of regional value chains in the region and promoting the upgrading of domestic value chains.Through the empirical analysis,the main results are as follows:(1)The development of the productive service industry has a positive effect on the upgrading of the manufacturing value chain,and different productive service industries have different effects on the value chain development.From the point of view of classification of knowledge and technology,the dynamic effect of knowledge intensive productive services on the value chain upgrading is greater than that of traditional transportation and other productive services.(2)The development of productive services has improved the level of regional domestic value chain and promoted the upgrading of domestic value chain.Compared with the central and western regions,the productive service industry in the eastern region has a greater effect on the regional domestic value chain.And with the passage of time,the role of productive services in the promotion of the value chain upgrading is becoming more and more obvious.(3)Under the high decentralization,the development of local protectionism,industrial clusters and fierce competition in the market have hindered the upgrading of the domestic value chain,and the role of R&D investment in upgrading the value chain has not been fully exploited.
