On Accession To The Wto From The Perspective Of The Performance Of The Chinese Industrial Sector Effect

Industry plays an important part in the national economy, and the capital profit ability of industry affects the development of Chinese economy directly. In the five years after WTO accession, with the development of economic globalization, Chinese industry has been more mature, and developed gradually. The drastic competition by WTO accession didn't concussion the average capital profit ability of industry. On the contrary, the average capital profit ability of industry increased gradually. This is quite different from forecast by most exports before accession. Therefore, the research on the -changes of capital profit ability of Chinese industry after WTO accession is important in theory and practice for healthy and stable development of society and economy. Besides, we try to find out whether the changes represented structural characters among the industries, which is useful for the related department to grasp the character of Chinese industry and to establish relevant policies.Based on panel datum of industries in China, We analyzed the changes of capital profit ability of Chinese industry after WTO accession. Using the panel data model, we try to explain the changes from four aspects, such as the degree of competition, the level of technology, economies of scale and the degree of trade freedom. Similarly, we establish another four models, and make analysis through the positive study on the structural characters among the industries after WTO accession.The results show that effect factors of capital profit ability of Chinese industry have changed after WTO accession. Especially the relationship between economies of scale (the degree of trade freedom) and capital profit ability of industry has changed remarkably. After WTO accession, Chinese industry regardless of the condition of the realization of economies of scale, so it appears obviously diseconomies of scale on the average. However, the increase of the degree of trade freedom is useful for Chinese industry to improve the capital profit ability. But the further results show that the changes represented distinctly structural characters among the industries. This is because there are many differences between peroration character and comparative advantage in each industry, and the effects of the degree of competition and economies of scale on capital profit ability of industry are quite different.
