Financing Restriction,Infrastructure and Dynamic Evolution of Technological Structure of Export in Manufacturing Industry

This paper reveals the mechanism of action of infrastructure and financing restriction for dynamic evolution of technological structure of export respectively from the perspective of mechanism and empirical resolution with partial differential and system GMM estimation method based on the expansion of Redding model.The result shows,though technological structure of export in China has been greatly improved in recent years,the technological structure of export in local manufacturing industry has not surpassed foreign-funded manufacturing industry and the export of products with high technical content mostly depends on foreign-funded manufacturing industry;second,the positive marginal effect of infrastructure improvement on the upgrading of technological structure of export in manufacturing industry is greater than foreign-funded manufacturing industry and can help the technological structure of export in local manufacturing industry catch up with and surpass foreign-funded industry.The reduction of financing restriction degree is good for the upgrading of technological structure of export in China,but does not have significant effect on the technological structure of export in local manufacturing industry to catch up with and surpass foreign-funded industry.Finally,the catching-up mode of technological structure of export in local manufacturing industry is similar to manufacturing industry in most developing countries.The participation of local enterprises in export has significant feature of international market power weakeningand is adverse to dynamic evolution of technological structure of export.
