Data collected for 6 years （2009-2014）, HHI （Herfindahl-Hirschman index technique） was used to analyse the market behaviour and the movement of the market towards monopoly or to lead to PPC （pure and perfect competition）. Based on the above, by analyzing the defined market data, it was found to be a promising market and tends to competition. Of course, this serves the interest of the client, which is the efficiency and speed of cargo handling safely and at the lowest cost.展开更多

Through a series of data analysis,it has been pointed out that China＇s surfactant industry will usher in a period of eliminating overcapacity and industrial integration in next decades, and mentioning that enterprises should prepare for the risks about market structure change and homogenized competition.展开更多

In economic articles, we see more attention to the dynamics of monopolistic competition and power companies, but it is less used the study of the sales dynamics of the sector and the curves that represent it. The proposed model uses as data the total number of subscribers to mobile phone lines to generate the logistic curves of each company and the total market, in search of main points singularities and stability conditions as predictors of the extinction of technologies and the shot-down of companies in the sector.展开更多
With the concept of security-spot market or security market with measurable space of agents, which was first given by Zhang （1998, 2000）, we continue to discuss the existence of equilibrium in such large economies. ...With the concept of security-spot market or security market with measurable space of agents, which was first given by Zhang （1998, 2000）, we continue to discuss the existence of equilibrium in such large economies. Under common conditions, we have claimed the existence of equilibrium in incomplete security-spot market with a continuum of traders. Because of the development from complete market to incomplete market, we have not only generalized Aumann＇s results in 1966, but also achieved a breakthrough on researching methods.展开更多
