The Technological And Economic Omparison And Analysis On The Environmental Infrastructures Construction Between China's Eastern And Western Small Cities

Through reforming and opening-up policy, China's economic development level was improved with a amazing speed, and the nation-building has achieve remarkable success with worldwide concern.But there were greater disparities between the eastern and western regions.with the strategy of urbanization, the small cities were developing with a high speed .Meanwile there's obvious improvement in population,scale,economy and quantity and quality of industry. But because of the developing models and other reasons,it has caused serious pollutions to the environment. In the meantime, environmental infrastructure could not keep up with economic development,and there's imbalance of industy in many aspects, such as scale ,quantity and technology ,especially in the eastern and western areas.Considering China's current stage of development , speeding up the ienvironmental infrastructure of small towns(especially in western area), narrowing the gap of socio-economic development and environmental quality gap between eastern and western areas has significant meaning in accelerating balanced development among regions,and achieving sustainable development and harmonious society.The paper compares the eastern and western areas's characteristics of environmental infrastructure and the development features in combine of eastern and western geographical conditions and their difference in economic and social development. Then the coclusion is that considering the inter-regional differences of environmental infrastructure between the eastern and western area, and match thef technology in order to offer some recommendations to guide the future environmental infrastructure construction in the current and future.Firstly, considering the success and features of the development in small cities, this paper draws the conclusion that transform the mode of economic growth is a essential way to achieve sustainable development of small towns.But to consider the actual situation, the end treantment through environmental infrastructure is still an efficient measure.Eastern and western area, as the regions having obvious differences in development, reflect the characteristic of China's cunrrent environmental infrastructure. It is easier to find the factor through the comparison of small towns environmental infrastructure in the two regions in space.Based on the overall Statistics and data, the paper take the influence factors with geographic conditions, population quality and the levele of education technical strength and management level and other infrastructure construction in concern.Then the comparison of quantity and detailed analysis is made, about the natural and social background of the environment infrastructure, and the conclusion is that on all aspects, western area lags far behind the eastern area. The paper also pointed out that the difference between eastern area and western area in developing ability is inffluenced by comprehensive effects, so that the selection of technology and related policy must take full account of the actual situation in the area.Eastern area has obvious advantage in the technology of infrastructure. Eastern environmental infrastructure experience has important lessons for the western areas of its construction, operation and management system.On the basis of field research in some small cities in eastern area and western area, some aspects , such as the process, treating results, operation and management of water treatment plants and waste water treatment plants in eastern and western areas, and their advantages and disadvantages were summarized, analyzed and compared, to demonstrate the applicability of the eastern environmental infrastucture technology to use in the western area, and it helps to select and match the technology of the western small cities in environmental infrastructure.The last part discuss the relationship between development and economic growth in China's environmental infrastructure ,and introduce the concept of grey correlation degree to analyze the convergence character, then draw the conclusion that environmental infrastructur project has difference in complete level, value,so the construction is in sequence. Through the comprehensive analysis and contrast, it provides suggestions for policies in technical choice and support, the government's management and supervises, as well as the development of marketization and financing.Overall, this thesis offers a basic analysis of the current situation of the environmental infrastructure in eastern and western cities and towns, as well as a conclusion and contrast about the different development background of natural society, affording a foundation for the construction of environmental infrastructure in small cities and towns in the future. It also illustrates the technical characters for the construction of environmental infrastructure in distinct areas, the matching work, and some reasonable suggestions for the policies. In conclusion, all these above can no doubt make a significant purpose for founding a economically suited system and macro policy system to support environmental infrastructure in small cities and towns.
