China's reform and opening up in the area of circulation are an important component of the establishment of a socialist mgrket economy system. Prior to reform and opening up, this area had long been characterized by a high level of centralization, closedness and segmentation. The domestic market was isolated from the overseas market and internal trade from foreign trade, and each had its own management system and policy environment. The thirty years of reform and opening up, however, have put a new face on the institutional environment of circulation: an open and modern system of circulation has been basically established, an embryonic WTO-consistent business administration system is taking shape, and the extension Of business and trade service ixidustries has facilitated institutional innovation. The main experience of reform is the following: first, taking opening up as the leading principle and making use of opening up to promote reform; second, following an incremental path of dealing with the easier issues before the harder ones, building up while you tear down, and gradual improvement; and third, breaking through the traditional framework of commodity circulation and establishing new business systems that accommodate more service industries. The economic implication of China's reform experience is as follows: an export-oriented strategy must inevitably be chosen as the point of entry for reform; there is an inherent linkage between market structure and human capital in the circulation of goods and services; and expanding the circulation of non-material goods is an important basis for institutional innovation. 展开更多
