Optimization Of Investment Environment In Gansu Province Based On The Perspective Of Environmental Carrying Capacity

Investment is one of the key factors to promote economic growth, it has very important significance to the regional economic growth. To attract foreign investors is the long term for the local government to revitalize the local economy. Gansu Province is relatively backward western regions, while the degree of opening up to the outside world increasing, the speed of economic development gradually increasing, but the shortage of funds still restricts the economic development of Gansu Province, which makes Gansu Province relatively backward of the west. To achieve sustainable economic development, it is necessary for Gansu province to actively attract foreign investment. It is the inevitable choice to make a correct evaluation and an improvement to attract more investment, because regional investment environment is very important to attract the number of investment. Therefore, it has important practical significance to evaluate the investment environment of Gansu province.The investment environment can be divided into hard environment of investment and soft environment of investment. The hard environment of investment in all parameters can be are quantitative analysised, except the ecological environment. Soft environment of investment also has a part of indicators can be quantified analysis. Therefore, the quantitative analysis of the investment environment mainly uses the investment environment carrying capacity model, which is the objective existence value that can use the formulation to calculate. The carrying capacity of the investment environment refers to the ability of the environmental system to bear the human economy in a certain period of time. Investment environment capacity is the foundation of realizing the sustainable development of regional economy. If the human economic and social activities is more than local environmental carrying capacity, we can not achieve the sustainable development of the economy, ande is also not conducive to attract more investment. In the soft environment of investment, the non quantifiable indicators is an important part of the investment environment, and has the characteristics of non material and fuzziness. These indicators and the degree of economic development are closely linked, the higher the degree of economic development, the greater the impact on the soft environment of investment activities. Therefore, the evaluation of the investment in the soft and hard environment is related to the overall situation of regional development, and it is significant to promote social progress and regional economic development.The research in the discussion, based on the theories of investment environment and the relationship between the investment environment and the economic development, and then using non quantitative analysis method and qualitative analysis method to analyse to evaluate the Gansu Province's hard environment and soft environmentfor. At last, according to the optimization theory, trying to explore the measures to optimize the investment environment of Gansu and enhance the investment attraction. In the quantitative analysis phase, select the quantified index of soft environment, and the index of hard environment except the ecological environment, using the investment environment carrying capacity model, from the three aspects of environmental and economic system, social living system and natural resource and environmental system, to establish investment environment carrying capacity system. Then using the state space method and the principal component analysis method to calculate the Gansu provincial environmental carrying capacity and environmental carrying rate, to analysis the investment environment in Gansu Province. In the non qualitative analysis stage, select indicators of soft environment that can not be quantified and indicators of ecological environment, to analyze the current situation and problems of the investment environment in Gansu Province, and to obtain the investment environment of Gansu province. Through the study, the economic situation of Gansu province and the degree of coordination of the environment is poor, the soft environment is not perfect, there are deficiencies in the thought, talent, policy, legal system and so on. Therefore, the optimization of the investment environment must start from two aspects of the soft and hard environment, seize the most weak links, focus on the optimizing of the most important environmental improvement, step by step, conducting system optimization.
