我国从RCEP成员国进口矿产品的潜力评价OACHSSCD

As a major global consumer of mineral resources,China has a high import dependence on crude oil,iron ore,and other commodities.To analyze China's trade potential for importing mineral products from Regional Comprehensive Economic Partnership(RCEP)member countries,this study calculates comparative advantage and trade complementarity indicators based on trade data from 2011-2020,quantifying the intensity and potential of trade relationships.The global principal component analysis is used to evaluate the trade facilitation levels of RCEP member countries,which are then integrated with factors such as economic scale,geographic distance,land area,and population into a stochastic frontier gravity model framework for empirical analysis.The study finds that China's economic scale,population growth,and land area significantly promote mineral imports,while the long geographical distance and the large population in exporting countries pose obstacles.Enhancing infrastructure,optimizing the customs environment,and signing free trade agreements can effectively improve trade efficiency,while complex government regulations,high tariffs,and underdeveloped finance and e-commerce will restrain trade efficiency.
