| In recent years,"digital economy" has become a hot word.China has clearly pointed out in the Fifth Plenary Session of the 19th Central Committee that to develop digital economy and build digital China.Although the development of China’s digital economy is very rapid in recent years,there is still a gap with Western developed countries in terms of the breadth and depth of development.In addition,in recent years,the overall trade situation of our country is not optimistic,and the trade friction is intensifying.To deal with the ever more intricate trading landscape,it is urgent for our country to improve the competitiveness of export products.So how to improve the export competitiveness of our country’s products in the digital economy environment?What is the theoretical transmission mechanism?Based on current research and development,the development of digital economy will drive the improvement of China’s export competitiveness,while the digital information technology,as the core of digital economy,can improve the added value of export products through innovative export methods,and then improve the export competitiveness of China’s products.Therefore,it is particularly important to understand the effect and influence mechanism of digital economy on the export competitiveness of China’s products,and make use of its positive promoting effect.In this paper,the digital economy and export competitiveness related to the basic concepts and literature review;Secondly,it explains and analyzes the theoretical mechanism of digital economy’s influence on export competitiveness from three different aspects:technological progress effect,trade cost decreasing effect and material capital accumulation effect.Following that,employing the technique of factor analysis,30 provinces and autonomous regions were taken as the research object,and 5 first-level indicators and 16 second-level indicators were adopted to construct the digital economy development level evaluation system.On this basis,export competitiveness index was constructed by using the trade quota of each province and autonomous region over the years.Next,it explores the influence of digital economy on export competitiveness from an empirical perspective,and tests the rationality of the influence mechanism mentioned above through the intermediary effect model.In conclusion,the following findings can be drawn:the development level of our digital economy and export competitiveness has been improving year by year,but the difference of regional development is still greater,the eastern region is obviously higher than the west;Digital economy has a significant impact on export competitiveness,that is,under certain conditions,the development of digital economy will indeed promote export competitiveness.The effect of digital economy on export competitiveness is different in different regions.The effect of digital economy on export competitiveness of eastern regions is stronger than that of central and western regions,the effect of high transport infrastructure level is stronger than that of low transport infrastructure level,and the effect of digital economy on export competitiveness of local enterprises is stronger than that of foreign-invested enterprises.The effect of digital economy on export competitiveness should be realized mainly through the effect of technological progress and material capital accumulation,but the effect of decreasing trade cost does not play the mediating role expected by the theory.According to the research conclusions of this paper,several targeted conclusions are put forward:in the process of developing digital economy,our country should strengthen the construction of digital economy in the central and western regions,narrow the gap of digital economy level in the eastern,middle and western regions,and drive the coordinated development of the eastern,middle and western regions.To optimize the domestic digital economy environment,break traditional administrative barriers,promulgate laws and regulations,timely adjust laws and regulations according to the continuous development of digital economy,timely correct regionalism,and create a national integrated digital platform and large market;Increase the construction of digital communication infrastructure,comprehensively upgrade the hardware infrastructure of the digital industry,make full use of the permeability of digital technology,promote the optimization of export structure;We should raise the level of digital technology,intensify innovation,vigorously train professional technical personnel,give full play to their driving role,and promote technological innovation. |
