The Impact Of Intermediate Trade Liberalization And Import Diversity On Enterprise Innovation

China’s import trade has developed rapidly.The import volume has been on the rise for more than ten years,and the import field has been expanding.The import sources have also shown a diversified development trend.The degree of liberalization of China’s import trade has been deepened,especially the intermediate products,which account for an absolute advantage in the proportion of China’s imports have played an important role in China’s use of foreign resources to seek its own development.In the post-crisis era of the global economy,China’s economy facing the need of transformation and upgrading.We must grasp innovation as a new economic engine to leverage a new round of economic growth.As the most active micro-subject,enterprises have the demand of continuously innovating new products to enhance market competitiveness.The deepening of trade liberalization in intermediate products facilitates enterprises to use diversified imported intermediate products and provides opportunities for enterprises to realize innovative development.Therefore,this paper aims to study the impact of trade liberalization of intermediate products and the diversity of import of intermediate products on enterprise innovation.This paper reviews the relevant literature on the impact of trade liberalization on innovation and the impact of import diversity on innovation.It is found that the existing literature lacks theoretical research on the impact of trade liberalization of intermediate products on enterprise innovation,especially on the import diversity of intermediate products.Therefore,the research on the impact of trade liberalization of intermediate products and import diversity of intermediate products on enterprise innovation in this paper is innovative to the existing literature.Next,this paper analyzes the current situation of China’s trade liberalization,import of intermediate products and enterprise innovation,and analyzes the impact of trade liberalization of intermediate products and diversity of import of intermediate products on enterprise innovation by constructing a theoretical model,and puts forward a research proposition: trade liberalization of intermediate products is conducive to promoting enterprise innovation,especially when the diversity level of import of intermediate products is increased,this promotion effect will be further strengthened.This paper uses the matching data at the micro level of the enterprise to testthe proposition put forward by the theoretical analysis part.Further,in order to enrich and deepen the research content,this paper divides sub-samples to consider the differential impact of intermediate trade liberalization and diversity of intermediate imports on the development of innovation activities of different types of enterprises from the four dimensions of enterprise nature,location,adopted trade methods and countries of origin of intermediate imports,and explains the conclusions accordingly.Finally,this paper integrates the research conclusions,and puts forward some countermeasures and suggestions from three aspects: further promoting the trade liberalization of intermediate products,implementing the import diversification strategy,and promoting the innovation of manufacturing enterprises.
