| With the development of a new round of information industry and the gradual transformation of global manufacturing industry from single production type to "production+service" type,accelerating the integration,symbiosis and coordinated development of manufacturing industry and service industry is an inevitable choice to realize the high-quality development of manufacturing industry.Producer service industry is a kind of service industry directly related to manufacturing industry,which runs through the upstream,midstream and downstream of the whole production process of manufacturing industry.Putting professional service elements into manufacturing industry is the key link to accelerate the integration of secondary and tertiary industries.Therefore,if a country wants to improve the competitiveness of manufacturing industry,the role of producer service industry should not be underestimated.Based on the liberalization of producer services trade,this thesis studies its impact mechanism on the international competitiveness of manufacturing industry,and further explores its impact effect on the international competitiveness of manufacturing industry in different policy fields,which has important theoretical and practical significance for improving the international competitiveness of manufacturing industry.Firstly,this thesis combs the relevant literature from three aspects:the liberalization of producer service trade,the international competitiveness of manufacturing industry and the relationship between producer service trade and the international competitiveness of manufacturing industry;Secondly,combined with the relevant literature at home and abroad,this paper analyzes the impact mechanism of producer services trade liberalization on the international competitiveness of manufacturing industry;Finally,by using the cross-border panel data of 12 manufacturing industries in 33 countries from 2005 to 2014,this thesis makes an empirical study on the impact of producer services trade liberalization on the international competitiveness of manufacturing industry based on the reverse measurement of overall restriction index and five types of policy area restriction index.The heterogeneity test of manufacturing industry distinguishing countries and different technical levels,the robustness test and quantile test based on different calculation methods of core explanatory variables are further carried out.The conclusions of this thesis are as follows:(1)Whether based on the overall restriction index or the restriction index of five policy areas,the liberalization of producer services trade will significantly influence the international competitiveness of manufacturing industry and the liberalization of services trade measured based on the overall restriction index has a greater impact on the international competitiveness of manufacturing industry.(2)In terms of five policy areas,the improvement of foreign capital access openness has the greatest impact on the international competitiveness of manufacturing industry,followed by the openness of competition fairness,regulatory transparency,movement of natural persons and other degrees of discrimination.(3)Different countries show that the liberalization of producer services trade measured by the overall restriction index has a significant positive correlation with the international competitiveness of manufacturing in developed and developing countries,but the impact coefficient on developed countries is greater;The impact of producer services trade liberalization on the international competitiveness of manufacturing in developed and developing countries is obviously heterogeneous,measured by the restriction index of five policy areas.(4)Based on the sub sample regression results of different manufacturing technology levels,the liberalization of producer services trade measured by the overall restriction index has a significant positive correlation with the international competitiveness of manufacturing industry with low and medium technology level,medium and high technology level,but has no significant impact on the international competitiveness of low-tech manufacturing industry.(5)The robustness test results show that after changing the measurement method of producer service trade liberalization,the results are still significant,indicating the reliability of the test results.(6)Quantile test results show that the liberalization of producer services trade has different effects on manufacturing industries at different competitive levels. |
