Research On The Influence Of Policy Resources Input On The Upgrading Of Industrial Value Chain In Xinjiang

Xinjiang,as a superposition area of policy resources input,since the western development,has gathered various resources mainly based on counterpart assistance to Xinjiang,which is mainly to promote industrial development.Xinjiang14 th Five-Year Plan put forward to promote industrial aid,most of the resources to deepen enterprise investment and technology exchanges.In addition,Xinjiang,as the core area of the Silk Road Economic Belt,has strategic advantages in industrial transformation and upgrading.In particular,in 2010,the input of policy resources injected new blood into Xinjiang ’ s industrial development,and provided policy assistance for the industry to embed in the international and domestic value chains.So,does Xinjiang ’ s policy resources input promote the industrial value chain ? What mechanism does policy resource input produce effect ? To this end,clarifying the effect and mechanism of policy resources input in Xinjiang on the climbing of industrial value chain will help to ensure and improve the efficiency of policy resources input,and further promote the climbing of industrial value chain in Xinjiang.Based on the above background,this paper summarizes the relevant literature review,and takes the research deficiency as the entry point,that is,there are few studies on the verification of the effect of policy resource input on the evolution of regional industrial value chain,and there are few studies on the upgrading of industrial value chain from the meso and micro aspects.Therefore,this paper studies from the above perspective.Specifically,firstly,the connotation of policy resources and value chain is defined,and relevant theories are combed.Then,this paper sorts out and analyzes the current situation of policy resource input and key supporting industries,and uses the input-output table data of Xinjiang in 2007,2012 and 2017 to preliminarily analyze the change trend of 42 types of industrial value chains,and analyzes the relationship between policy resource input and the evolution of industrial value chains.Moreover,this paper expounds the mechanism of policy resource input on the climbing of industrial value chain,and puts forward the research hypothesis.In order to verify the research hypothesis,the measurement index of industrial value chain is constructed and measured,and the climbing degree and ranking change of industrial value chain in Xinjiang are compared and analyzed.And further use the difference-in-differences model based on the industry meso-level and enterprise micro-level value chain to verify the effect of Xinjiang policy resources input on the industrial value chain.The interaction effect model is also constructed to verify its mechanism,namely,the mechanism of industrial agglomeration,loan preference,tax preference and government subsidies.At the same time,combined with Xinjiang textile and garment industry case analysis,further from the practical experience to reflect.Based on the above theoretical and empirical basis,the following conclusions are drawn:First,since 2010 policy resources increased rapidly,covering a wide range,but mainly concentrated in Xinjiang ’s ’ top ten industries ’.In addition,industry domestic value chain participation level is high,but its international value chain embedding has more potential advantages.Secondly,the input of policy resources significantly increased the international(global)value chain level of Xinjiang industry by about12 %,and increased the international value chain level of Xinjiang ’s top ten industries by about 20 %;the input of policy resources has increased the level of Xinjiang ’s industrial domestic value chain by about 25 %,and has increased the level of Xinjiang ’s ’ top ten industries ’ domestic value chain by about 30 %.Although the effect of policy resources input on the rise of industrial domestic value chain has not passed the parallel trend test,it still has reference significance.Thirdly,based on the panel data of listed enterprises in Xinjiang from 2008 to 2019,the PSM-DID robustness test results show that the value chain level of enterprises has increased by about 63 %,among which the policy resource effect of enterprise value chain is heterogeneous.The value chain level of state-owned enterprises has increased by about 65 %,while that of private enterprises is about 45 %.Fourth,the verification results of the mechanism show that,in terms of the direct effect,policy resource input promotes the climbing of the industrial international value chain through industrial agglomeration,but hinders the climbing of the industrial domestic value chain;in terms of indirect effects,tax preference,credit preference and government subsidies have significant positive effects on the climbing of enterprise value chain in Xinjiang.
