Research On Impacts Of The Development Of Knowledge-intensive Service Industry On Productivity Of China’s Manufacturing Industry

As a big manufacturing country,the added value of China’s manufacturing industry exceeded $4 trillion in 2018,accounting for 29.41% of China’s GDP and28.31% of the world’s share,nearly doubling the United States.Manufacturing with such a considerable output plays a significant role in promoting the level of economic development.However,we should also realize that China’s manufacturing industry is "big but not strong",the overall labor productivity is not high,and the added value of products is low.At the same time,in recent years,China’s manufacturing industry is facing problems such as rising raw material prices and labor wages internally,and externally facing high-end manufacturing back-flow under the trend of "counter-globalization" in developed countries and diversion of low-end manufacturing in low-developed countries.The “processing plant” model that once relied on low-cost labor has been unable to continue to support industrial development.The lack of industrial growth has forced China ’s manufacturing industry to transform and upgrade to a knowledge-intensive industry.The key to upgrading is efficiency improvement,and from the theoretical research and real life,it is not difficult to find that the role of knowledge-intensive service industry in the development of manufacturing industry cannot be underestimated.Because as a high-level production factor,knowledge-intensive service industry invests to the process of industrial production,helping manufacturing enterprises reduce production and operating costs and promote technological innovation,thereby improving manufacturing efficiency.Therefore,this article aims to explore the effect of the development level of knowledge-intensive service industry on the production efficiency of China’s manufacturing industry,trying to propose new ideas and methods for the improvement of China’s manufacturing efficiency.This article first sorts out the relevant researches at home and abroad,and finds that there are few researches related to the production efficiency of knowledge-intensive service industry and manufacturing industry,and few of them involve service industry heterogeneity.Then,according to the relevant statistical data,the development status of production efficiency of knowledge-intensive service industry and manufacturing industry is analyzed,and the labor productivity level of manufacturing industry in various regions of China and in various industries are measured,and problems are found from the status analysis.Then through theoretical analysis,it is found that knowledge-intensive service industry has a significant effecton manufacturing efficiency through the four mechanisms of economies of scale,specialization,competition and spillover effects.Finally,collect panel data of 30 provinces and cities and 27 manufacturing industries in China from 2005 to 2017,and select the level of human capital,transportation convenience,industry competitiveness,R&D investment,urbanization level and fixed Empirical analysis of asset investment,industry competitiveness,R&D investment,and industry size as control variables.The empirical research is carried out from four aspects: first,starting from the overall level,the empirical results show that the development of knowledge-intensive service industry has a significant role in promoting manufacturing efficiency,except for R & D investment,other control variables all have positive effects.The second part is knowledge-intensive service industry segments,and it was found that the four sub-sectors,information transmission,computer services and software,financial services,leasing and business services,scientific research,technical services and geological survey services all have positive effects on the production efficiency of the manufacturing industry,they have passed the 5%、1%、5% and 1% significance level respectively.The third is to return to the central,eastern and western parts of China from the perspective of the overall and subdivided industries.The results show that for different industries and different regions,the degree of influence varies,and even because of differences in regional economic development levels,the direction of influence will be opposite.The fourth is the regression of manufacturing industries with different factor intensity.The results show that the whole knowledge-intensive service industry and sub-sectors have more significant influence on the labor-intensive manufacturing industry.Finally,based on the conclusions of the study,this article puts forward suggestions that are conducive to the development of China’s manufacturing efficiency,hoping to provide some useful references for the overall allocation of China’s manufacturing production resources and the promotion of their production efficiency.
