| In recent years,with the development of the world economy and the evolution of the international division of labor system,China’s manufacturing exports have lost competitiveness in the international market due to the loss of labor cost advantage,and export growth has been weak.As a large exporting country of manufacturing industry,China only pays attention to the size of export volume and can not truly reflect the international status and competitiveness of China’s manufacturing industry.The more important measure is the technological content of manufacturing exports,which directly reflects the sophisticated of manufacturing exports.s level.Under the guidance of China’s "manufacturing service" policy,accelerating the integration of manufacturing and service industries and deepening the embeddedness of productive services in the manufacturing process has become an important research topic in the manufacturing industry.This paper selects the most representative high-tech manufacturing industry in the manufacturing industry,and studies the effect of the import of productive services on the export sophisticated of China’s high-tech manufacturing industry.First,the export sophisticated of China’s high-tech manufacturing industry and the import of productive services.The current situation carries out data description and analysis,and from the theoretical level,combined with the three mechanisms of technology spillover effect,variety growth effect and economies of scale effect,analyzes the impact mechanism of the import of productive services on the export sophisticated of China’s high-tech manufacturing.Secondly,using the multiple linear regression model in econometrics to study the effects of the total import of productive services and the import of industrialized services on the export sophisticated of China’s high-tech manufacturing,and compare the total import of productive services to China.The degree of export sophisticated of technology manufacturing and the significant impact of the overall export sophisticated of all commodities.According to the empirical results,in general,the import of productive services has a significant positive impact on the export sophisticated of China’s high-tech manufacturing industry,but the impact of the import of productive services in different industries on the export sophisticated of China’s high-tech manufacturing industry is different.Transportation,insurance,exclusive royalties,computer and information services have apositive correlation with the export sophisticated of China’s high-tech manufacturing industry;finance and construction have a negative linear correlation.Finally,based on the reality of China,the empirical research results are analyzed and summarized,and relevant policy recommendations are put forward. |
