The Influence Of Enterprise Heterogeneity On Beijing’s Export Of Service Trade

Since the 21 st century, enterprise heterogeneity trade theory has become the focus of international trade theory. The development of international trade theory has gone through four stages: initial classical trade theory, new classical trade theory, new trade theory and the latest new trade theory(enterprise heterogeneity trade theory). International trade theory perspective progressive layers extend gradually from the macro level to the micro level, from a business perspective to study microscopic reality of the business formation, structure and distribution of the benefits of trade to make a reasonable explanation. Enterprise heterogeneity trade theory has been studied by foreign scholars from both theoretical and empirical perspective, summed up the production rate of the outlets, the production rate will be engaged in domestic trade, lower productivity will force enterprises to withdraw from the market. In recent years, along with the optimization of industrial structure transformation, trade in services has become a strong support of economic development, trade in service exports become one of the core issues in international trade concern. Beijing as the capital, is an important national base for the development of trade in services is also one of the important economic hub. Beijing rely on the advantages of talent, technology, information, and other aspects of the market, the rapid development of trade in services. However, the traditional trade in services trade development still occupy a certain position,thus it is the means to accelerate the promotion of high value-added high-tech goods and services trade development and increase service productivity,and has become an important way of competition to further develop Beijing trade in services,optimize the industrial structure and the participation of domestic and foreign. The applicability of some domestic scholars research enterprise heterogeneity trade theory mainly concentrated in manufacturing range, has very little study for the service sector.. Therefore, this specific relationship based on enterprise heterogeneity trade theory research firm productivity and export trade in service in Beijing.Firstly, the context of the development of international trade theory expounded, a combination of theoretical and empirical research scholars at home and abroad, on the basis of a detailed presentation of the classical model of enterprise heterogeneity trade theorymodel the impact on exports. Then 2006--2014 services sector industry segments empirical analysis of data affect heterogeneity on industry exports. During the research,this paper by setting Cobb- Douglas production function to calculate total factor productivity, export growth service industries represented exports, and time series analysis and panel industry productivity and estimate the scale of export industries. The results showed that the test results of the empirical data services sub-sector is basically consistent with the conclusion of new new trade theory, namely having a positive correlation between productivity and service export trade services; and there is a balance between long-term stability relations, service productivity is the reason trade in services exports. Finally, based on research findings, it made specific recommendations to promote the Beijing service enterprises for export growth and productivity improvements.
