Study On Domestic And Abroad Development Stage Coefficient Of The Ecological Value

This thesis paper establishes settle mechanism of concrete expression of the calculating model of development stage coefficient, aiming at the circumstance that traditional calculating model is in need of theories to prop up certainly. And this paper considers society, economy, and human living's level among this rational process, effectively solves the puzzle that humans'requirement to environment quality is different in the diversity of settings, such as different developmental stage and different nation and so on. Then gets deductive method of the calculating model of development stage coefficient that can accurate symbolize the will level of human's payment to the ecological value.This thesis establishes settle mechanism of the horizontal coordinate x in model of the ecological value development stage coefficient first, then deduces establishment method of developmental stage coefficient's calculating model; According to the relation of the United States ,Japanese'economy development and environmental protection history, found out history period of change that the will of paying to the environment is notable for the United States and Japan, and it's corresponding economy development stage, then get concrete expression of the ecological value development stage coefficient of the United States and Japan, then chooses model that the displacement of the horizontal coordinate x is 25/6 and 35/12 to respectively calculate the United States and Japan's past years'developmental stage coefficient. In the light of current stage level of economy and the stage of environment protections work in China, gets various possible choices of model than can symbolize the trend of China's developmental stage coefficient in future and it's concrete expression.Next, pass contrast analysis to data of the past years'development stage coefficient of China, the United States, Japan, draws following conclusions: (1)For the United States and Japan, the development of development stage coefficient has run to mature stage of increasing gently from the farthest growth; The developmental stage coefficient of China gets behind with the United States, Japan far and far, and the will still be placed in the lower level to pay ecological environment for people of China. (2)According to growth process of development stage coefficient of the ecological value of the United States and Japan, draws theories relation that with the trend of economy development, society progress and human's requirement, development stage coefficient is totally increasing. (3)Pass analysis and arguments of the antinomy that requests to support the ability with limited resources and environments and the stable, fast economy growth in current in China, and draw lesions from development mode of the United States and Japan, chooses model that displacement of the horizontal coordinate x is 8/3 to symbolize the trend of China's developmental stage coefficient. Videlicet, the trend that when the Engel coefficient is in stage of 50%~30%, human's will pay to the ecological value appear to the biggest jump, is a reasonableness choice to China.End, this paper inquiries motive mechanism of the rational choice of China. At low in the peak value of the U curve, China must carry out virtuous cycle of the ecosystem environment in advance; Establishes exactitude national environment policy, moderate the economy, the coordination of the society and environment etc; Changes traditional theories of human's need, make Chinese people in the lower life level stage put forward the higher request to ecosystem environment.The establishment of traditional model of development stage coefficient just limits to resolve problem of the environment value, research of the paper opens the research realm of traditional model, this paper studies the function relation of economy, society, humans'development and ecological environment from the point of view of developmental stage coefficient, putting forward relative perfect growth mode of development stage coefficient of the ecological value that Chinese should adopt.
