| With the continuous acceleration of the process of economic globalization,the world economic structure is undergoing an unprecedented transformation.On the one hand,traditional manufacturing enterprises need to face the threat from the rapid development of service trade,on the other hand,their own industrial restructuring is also imminent.Manufacturing industry is the core manufacturing enterprise of service from manufacturing to service link transfer dynamic process,as a connecting link,manufacturing and service industries manufacturing service can not only make manufacturing enterprises to carry out the strategy of service,at the same time will promote the countries all over the world on a higher level,technological innovation,and constantly improve the technology level of manufacturing exports.In this paper,on the basis of existing research,using output tables in the WIOD database and the import and export data of the relevant countries in the Uncomtrade database,selecting 42 typical representative countries,manufacturing level of service and manufacturing export technology complexity are calculated separately.Besides,according to the OECD database's division of manufacturing technology level,the manufacturing industry can be divided into low,medium and high technology level manufacturing.Using cross-country panel data to study the differences in manufacturing service technology to the manufacturing technology export complexity of different technical levels;at the same time,this paper further studies the heterogeneity of manufacturing service technology of developed countries and developing countries on the complexity of manufacturing export technology based on regional differences.The research results show that:(1)Overall,when the control variables are not considered,the manufacturing service and the low-tech manufacturing export technology complexity show a U-shaped influence relationship.After considering the control variables,the influence relationship weakens.For the technical complexity of export of medium and high technology manufacturing industry,servitization of manufacturing industry has a significant inverse u-shaped influence.(2)After testing developed and developing countries respectively based on regional differences,the influence relationship between servitization of manufacturing industry and technical complexity of export of low-technology manufacturing industry in developing countries is significantly enhanced.The relationship between servitization of manufacturing industry and technical complexity of export of medium-technology manufacturing industry in developed countries is weakened.The influence of manufacturing servitization on the technical complexity of high-tech manufacturing exports in developed and developing countries remains the same. |
