| With the continuous innovation and application of new generation information and communication technologies such as big data,cloud computing,5g and artificial intelligence,digital economy and digital trade have developed rapidly and become a new key field of global economic competition.Meanwhile,the outbreak of COVID-19 accelerated the development of the world economy towards networking,digitalization and intellectualization.China’s economy has entered a high quality development stage from the high growth stage.Facing the new economic situation under the epidemic situation,the central government proposed to build a new development pattern of "double cycle",that is,the domestic big cycle is the main body,and the domestic and international double cycles promote each other.As a major economic province,Jiangsu Province has always been in a leading position in manufacturing industry in China.Under the background of national manufacturing transformation and upgrading,Jiangsu Province issued the three-year action plan for intelligent transformation and digital transformation of manufacturing industry in Jiangsu Province(2022-2024)to accelerate the transformation and development of manufacturing industry in Jiangsu Province.Based on the above background analysis,this thesis puts forward the view that digital trade promotes the manufacturing industry of Jiangsu Province to enhance international competitiveness,which is verified from two aspects of theoretical analysis and empirical test.This thesis summarizes scholars’ research on Digital Trade and international competitiveness of manufacturing industry,and defines relevant concepts,characteristics and calculation.Based on the above views and theories,this thesis mainly calculates and compares the development status of Digital Trade and international competitiveness of manufacturing industry in Jiangsu Province,and then establishes a model to empirically test the argument.Evaluate the development status of digital trade in Jiangsu Province from three aspects: network foundation,economic development level and consumption level and ICT service industry scale;The comprehensive value was calculated by principal component analysis.At the same time,select the revealed comparative advantage index(RCA index)and product export proportion(IEP index)reflecting export advantage,the international market share index(MS index)reflecting market share and the michaely volatility index(MI index)reflecting trade stability to build an index system to evaluate the current situation of international competitiveness of manufacturing industry in Jiangsu Province.The theoretical model is established according to the measured value,and the relationship between digital trade and the international competitiveness of manufacturing industry in Jiangsu Province is verified from the empirical level by using STATA software and benchmark regression method,and the endogeneity,robustness and heterogeneity are tested.Finally,specific suggestions are put forward for the development of digital trade in Jiangsu Province,the improvement of international competition in manufacturing industry and the promotion relationship between them.The development of digital trade in Jiangsu Province should focus on infrastructure construction,technological innovation and international cooperation,and improve the breadth and depth of digital trade;Jiangsu manufacturing enterprises should constantly improve their independent innovation ability,and government departments should focus on building and expanding emerging industries and characteristic industrial clusters of manufacturing industry;In particular,we should cultivate leading digital manufacturing enterprises in Jiangsu Province,optimize the industrial Internet Project in Jiangsu Province,and do a good job in industrial data management. |
