A Study On The Evolution Of The Symbiotic Innovation System Of Producer Services And Manufacturing

As a pillar industry of the national economy,manufacturing industry is an important driving force to promote the growth of China's real economy,and plays an important role in the national economy.At present,the manufacturing industry has been unable to completely get rid of low technology,low value-added products,the low-end value and other issues.It is imminent to improve the innovation ability of manufacturing industry in this context.As an intermediate input industry,producer service industry has a strong industrial connection with manufacturing industry and it can enhance the production efficiency of manufacturing industry and strengthen the core link of industrial value chain.And the important way to solve this problem is to use the role of "incubator" and "propeller" of producer service industry to realize the dual wheel drive of manufacturing industry and producer service industry,so that it is an inevitable choice to promote the efficiency of manufacturing innovation and industrial upgrading through industrial symbiotic innovation.The academic circles pay more attention to the relationship between manufacturing industry and producer service industry.The research about the evolution of symbiotic innovation system between manufacturing industry and producer service industry is not rich.It is worthy of further study about what are the influencing factors to promote the evolution of the two industrial symbiotic innovation systems and how these factors promote the system evolution.In view of this,this dissertation has important practical and theoretical significance.This dissertation studies the evolution system between manufacturing industry and producer service industry by using a lot of research methods,such as literature analysis,structural equation model method,evolution model method and simulation analysis method.At the same time,it learns from multiple theories,such as innovation system theory,industry symbiosis theory,synergetic theory and evolutionary economics theory.The dissertation includes main research contents as following :Firstly,the dissertation puts forward the conceptual model of the influencing factors of symbiotic innovation between manufacturing industry and producer services industry.The conceptual model of the influences factors takes the factors of innovation resources,industry embedding and institutional factors as the leading variables;and takes the ability of symbiotic innovation as the intermediary variable,at the same time puts the innovation performance as the dependent variable,and looks the environmental disturbance factor as the regulating variable.On the basis of a large sample questionnaire,the model's reliability and validity of each construct is tested.The correlation between variables is analyzed,the direct effect and intermediary effects are tested by Mplus7.0software,and the adjustment effect is checked by SPSS24.0 software.The empirical results show that innovation resource factors,industry embedding factors and institutional factors positively affect symbiotic innovation ability and innovation performance,and symbiotic innovation ability has a significant intermediary effect between each factor and innovation performance,and environmental disturbance factors have no significant regulatory effect on the relationship between symbiotic innovation ability and innovation performance.Secondly,the dissertation analyzes the evolution process of symbiotic innovation system of manufacturing industry and producer services industry and gets the conclusions as following:the evolution of symbiotic innovation system of manufacturing industry and producer services industry is divided into four stages,which is initial formation stage,growth and cooperation stage,interactive integration stage and collaborative innovation stage.Based on the value added data of manufacturing industry and producer services industry,the population density is obtained,and the maximum environmental capacity of symbiotic innovation system is obtained by data fitting method.Thirdly,the dissertation uses Hacken model to determine the order parameters of symbiotic innovation system between manufacturing industry and producer services industry and gets the conclusions as following: symbiotic innovation ability factor is the main order parameter that affects the evolution of symbiotic innovation system.Based on this,the basic evolution model is constructed based on the Logistic model,and the evolution model of each stage is constructed based on the different relationship between manufacturing industry and producer services industry in the symbiotic innovation system,which are parasitic model,partial reciprocity model,asymmetric reciprocity symbiosis model and symmetric reciprocity symbiosis model.At last,the dissertation simulates and analyzes each stage model.Finally,based on the analysis of the factors and dynamic evolution of the symbiotic innovation system between manufacturing industry and producer services industry,the dissertation puts forward policy suggestions from four aspects: strengthening the management of operating resources allocation;promoting the embedding intensity of manufacturing and producer services industries;strengthening policy guarantee;and improving the ability of industrial innovation transformation.
