China's Pharmaceutical Business Industry Concentration Of Empirical Research

The Commercial Medicine in the world is concentrating gradually under the external adverse competitive environment and economies of scale. Now it becomes one of the most concentrated industry. But there are a lot of problems in Chinese commercial medicine in the fast-growing, such as low degree of industrial concentration, separate market structure which lead to low economic efficiency. With the progress of global economic integration, if the Chinese commercial medicine wants to survive global competition, it must improve it's competitiveness. Under this background, chinese commercial medicine which is in the middle of the transition process, is urgent to look for feasible method through theoretical research, so we can promote the optimization of the industrial structure and industrial organization, and improve the competitiveness of the whole industry. Industrial concentration,in SCP(Structure-Conduct-Performance)analytical frame of traditional industrial organization theory, is one of main factors in forming market structure, and affects market performance by influencing market conduct. The level of concentration has always been the key content of industry industrial organization theory.This paper's research object is Chinese commercial medicine. The basic characters in market structure of Chinese commercial medicine are decentralized competitive structure, low concentration level and non-economy in scale on enterprise level. So, it's quite necessary to re-integrate the market structure of Chinese commercial medicine. On this point, the study on concentration level and it's influencing factors of Chinese commercial medicine should be of great significance. Especially, With the progress of global economic integration, Chinese commercial medicine is facing more and more intensive international competition. Thus, how to optimize industrial structure and enhance international competitiveness has already become an urgent issue. So, the study on the market structure of Chinese commercial medicine is in the perspective of the concentration of Chinese commercial medicine. Combined with current situation of Chinese commercial medicine, the author have a regression analysis of the relationship between the industry concentration and it's influencing factor. Then get a conclusion . At last, according to the result of the regression, the author provide some suggestions which has a practical significance to inerease the industry concentration degree of chinese commercial medicine.
