AN ANALYSIS OF THE INVESTMENT ENVIRONMENT OF CHINESE CITIES

本文运用熵的原理探讨了中国城市投资环境的熵状态特点和熟化类型，并在此基础上提出了完善城市投资环境的若干措施。

The investment environment is the organic whole of a series of key elements of production and conditions of production that could promote the increment of capital. It is the combination of the following four aspects: internal economic scale, external economic scale, transport economic scale and urban economic scale. The investment environment consists of subject system. interrelated system,transmission system and service system.The crux of the investment environment is the chance for choosing the optimal combination of key elements of production and conditions of production. If a region has the optimal combination of key elements of production and conditions of production, it has good investment environment. On the contrary, it does not have if the optimal combination of key elements of production and conditions of production, it has poor investment enviroment. The mathematical model for cities'investment environment could be expressed by applying the principle of entropy of thermodynamics. The entropy is the measurement of complication of relations among all kinds of enterprises in cities. The basic features of entropy values of the investment environment of Chinese cities are:the values of coastal cities are higher than those of inland cities, the values of open cities are higher than those ordinary cities. and the values of big cities of are higher than those of small cites.Utilizing the two concepts of the degree of development (Ssh) and the increase rate of investment environment (Sch) . the cities' investment environment could be divided into four types:(1) Increment type Ssh> 1. Sch>1(2) Stable type Ssh> 1, Sch<1(3) Potential type Ssh< 1, Sch> 1(4) Development type : Ssh< 1, Sch<1The three basic measures to perfect the cities' investment environment are to urbanize the enterprise gathering, to pluralize the industrial composition, to make the transmission system into a network.
