| Since China’s accession to the WTO,the impact of tariff barriers has been greatly reduced,and bilateral and multilateral trade has been expanding.However,with the economic growth of various countries slowing down year by year in recent years,trade protectionism has become popular among western countries again.In the form of nontariff means such as technical barriers to trade and green barriers to trade,such nontariff barriers tend to be more targeted and concealed.It is also difficult for us to find appropriate measures under the current framework of WTO.In the context of China’s current carbon neutrality,the green production of agricultural products has also begun to be concerned.The carbon emission content of agricultural products in the whole production process can not be underestimated.In addition,China is a large agricultural product producer,but China’s agricultural products have repeatedly hit a wall in the global market,which has greatly hit the export enthusiasm of China’s agricultural products,It has also affected the reputation of China’s agricultural products in the global market.Therefore,this paper will focus on the export of China’s agricultural products,as well as the implementation of the green trade barrier policy,and specifically study the effect of Japan’s green trade barrier system on China’s agricultural products export.Firstly,this paper combs the three relevant theoretical bases of green trade barriers:trade protection theory,sustainable development theory and information asymmetry theory.From the evolution of the concept of green trade barriers,this paper analyzes why countries implement green trade barriers and how green trade will appear.Secondly,this paper analyzes the specific implementation of Japanese policies related to agricultural products,introduces the evolution process of Japan’s green trade barriers,provides a reference for the improvement of China’s agricultural product inspection and quarantine system,combs Japan’s current green trade barriers,and analyzes where the biggest obstacle of these systems to China’s product export lies.After that,this paper analyzes the amount and types of agricultural products exported from China to Japan,and explains the specific impact of Relevant policies of Japan on China’s agricultural products from different aspects.As well as the implementation of trade policy for China’s current agricultural export structure for the biggest adverse factors what aspects.On the basis of theoretical analysis,this paper collects the annual data of China’s agricultural products exported to Japan from 2003 to 2020 in the WTO.The experimental group and the control group were created,and the dual difference model was used to analyze the policy implementation effect of Japan’s green trade barrier-"positive list system".Accurately identify the economic effects brought by the implementation of the system.The results show that the implementation of "positive list system" can promote the export of China’s agricultural products.The specific reasons are as follows: first,the formulation of policies contributes to the transparency of the process.The specific contents of the positive list system are the types of banned pesticides and the maximum allowable drug residues.The implementation of the system actually improves the transparency of sampling inspection in a disguised form.This enables export enterprises to avoid these risks in advance and optimize the trade environment.Second,the implementation of the positive list system shows that the inspection and quarantine and technical standards of importing countries have become more stringent,mainly reflected in the less use of pesticides in the planting process and the treatment of residual drug value after subsequent harvest.The improvement of these two requirements has improved the quality of China’s agricultural products,thus enhancing the export competitiveness.Finally,the above theoretical review and data analysis results put forward targeted and feasible policy suggestions for the development of agricultural products in China,including relying on regional characteristics,building independent brands and realizing professional production;Improve the added value of agricultural products;Speed up the formulation and implementation of standards;Adjust the export structure of agricultural products and disperse export risks. |
