| Since the reform and opening up,China's export trade of agricultural products has continued to expand.As of 2016,the export volume of China's agricultural products reached US$138.758 billion,an average annual growth rate of 15.44%compared with 2001.In general,the export trade of agricultural products in China has maintained a good momentum.However,China's agricultural products still face the problems of export markets concentrated in developed countries.At the same time,more and more countries are facing standard barriers from such countries as healthy consumption and safe consumption.Therefore,strengthening the standardization process and striving to narrow the gap between the level of agricultural standardization between China and developed countries is an important way and guarantee for the sustainable development of China's agricultural product export trade.Starting from the background of standard-dominant international competition,the paper uses international trade theories,the theory of standardized export trade effects,and market structure theory to explore the changes in the structure of export markets of agricultural products from the relatively advanced and relatively lagged standard of exporting countries.mechanism.At the same time,we analyzed the number of agricultural standardization institutions,the number of agricultural standards,the international standard adoption rate of agricultural standards,and the export market structure of China's agricultural products as a whole and subdivided industries,and applied entropy TOPSIS method to standardize the basic conditions and standardized quantities.And the quality of standardization reflects the level of China's agricultural standardization,and evaluates the export market structure of agricultural products from the perspective of staticity and dynamics.Then through calculation of the degree of closeness,the level of agricultural standardization is generally on the rise,that is,from a poor level to a good level.change.In the aspect of agricultural product export market structure performance,it fluctuates between2000-2005,between the poor level and the intermediate level;it continued to rise from 2006 to 2010,rose from the intermediate level to a good level;good from 2011 to 2016 The level rose to a good level.Using VAR model to analyze the impact of agricultural standardization on the overall effect of agricultural product export market structure changes,using Panel Data model to analyze the impact of agricultural standardization on the structural changes of China's five categories of agricultural export market.The research shows that in the short term,standardization will cause some resistance to the optimization of the export market structure of agricultural products due to the increase in the cost of AIDS production.In the long term,the promotion of agricultural standardization on the structural optimization of agricultural product export markets will gradually become apparent.Among them,the agricultural standardization level of food products,forestry products,and aquatic products has a positive effect on the structural changes of the export market of agricultural products,and forestry products are the most significant.Finally,combining theoretical and empirical analysis results,from the standpoint of strengthening independent innovation of standards,raising the technical level of standards;advancing the internationalization of standards,reducing standard conflicts and trade frictions;strengthening standard constraints and expanding the coverage of standards;improving the construction of standard information platforms and promoting standards Four aspects of communication and training were discussed. |
