The Ecnomic Structure Optimization And Sustainable Development Research

China has obtained the huge result in economy since the reform and opening policy, when people share the great result in economy joyfully, they obviously saw that the natural environment and the humanities environment proposed new challenge for humanity's survival and the development. For example, the population quantity suddenly inflates and the cultural quality is comparatively low; the resources is relatively short, the ecological environment is frail, the environment quality worsens day by day; the economy has not yet completely stepped onto the track which can enhance the benefit; the economical development disparity is continuing to expand between the areas, the rich and the poor intensifies; the industrialization, the urbanization and the modernization are uncoordinated and so on, these problems will become the barrier for the future development. However China has met not merely the development barrier, also the innovation opportunity. when the development barrier and the innovation opportunity unifies together, we first must do is that we should reconsider the modern industry civilization, study new form and new characteristic which the new challenge displays, and study China in 21 century how can transform from not sustainable development to the sustainable development, from the large-scale ecology deficit to the large-scale ecology construction, from unceasingly overdraws to the environment with demands to reasonably uses two kind of resources, from the environmental pollution to the environmental protection and steps into the civilization and the progressive time. Which are its solutions and policies, value orientation and correct way?The natural condition is unable to choose, yet the development pattern can choose. From now on, we must have decisively to give up the kind of not sustainable development pattern we used formerly and use the sustainable development pattern. The choice of Chinese sustainable development pattern is different with the developed country's development pattern, which key in improving the environment quality, also different with other developing nations'development pattern, which key in both the economical development and environmental protection. The choice of Chinese sustainable development pattern must be a innovation among the economic form, the production method and the life style under the ecology civilization frame In other words, the Chinese sustainable development pattern is under the ecology civilization frame, based on the union of the economical innovation, the technical innovation and the system innovation, establishment the nature, the environment, the population, the economy, the society coordinated development which satisfies the whole society's development which has the Chinese characteristic .The factors that affects the sustainable development are multitudinous, therefore, the research of this article mainly stresses on the industrial structure, the social system, the population, the resources, the environment and so on the main social economy system and the sustainable development relations, other structures cannot be concerned limited to the length. The readjustment of the economic structure is mainly refers to carry the adjustment between each economic sector that constitutes the whole national economy and each industrial form and their relations. The adjustments mainly include industrial structure, city and countryside structure, local structure, system of ownership structure and consumption pattern adjustment, between them , industrial structure adjustment play an important role in the entire readjustment and evolvement of the economic structure, and it is the key point in the readjustment of the economic structure research. The narrow sense of the economic structure readjustment may be understood for optimized promotion process of the industrial structure.We should do the research on the sustainable development from the city and the county, because it is an unit of the whole space systems, and moreover it is comprehensive. The region which has the different type and the different development phases has the different problem of sustainable development."Focusing on the whole world and beginning with the region"becomes a general principle of sustainable development in theory and the practice on the global, and it offers an operational way that realizes the sustainable development goal from the macroscopic aspect. Therefore, the article plays an important on the correlation between the economic structure optimization and the sustainable development based on the city of Langfang and carries on the appraisal of the sustainable development level and the ability using the quantity method, and on the foundation proposes sustainable developmental strategy and the countermeasure strategy which is foresighted and operational based on the economic structure optimization for Langfang. The content includes five parts as following:The first part: the main content includes the introduction part and some basic theory. The introduction part contains background and the significance of the research, the method and the technical route of the research, and the innovation and so on. And the basic theory contains the concept of economic structure, the connotation of economic structure optimization, the elementary theory of sustainable development and the basic theory of the correlation among the economic structure optimization, the economy growth and the sustainable development. The second part: Firstly it finds out the appraisal index system of the sustainable development in the domestic and foreign and carries on the earnest analysis for the good points and shortcoming of the different appraisal index system, then constructs the index system of sustainable development which is practically feasible and suitable for Langfang.The third part: the main content of this part is the comprehensive appraisal analysis of the sustainable development. Firstly it elaborates and use the quantity method of the system analysis and multi-statistical method such as the principal components analysis, the level analysis and the cluster analysis and so on, then carries on the quantity analysis of the sustainable development for Langfang and other 11 cities of Hebei province with the help of the statistical analysis software such as SAS, Eviews and SPSS, and based on the result gets the appraisal synthesis rate of the sustainable development level of the 11 cities, simultaneously take the cluster analysis and the synthesis appraisal on six counties, two areas and two cities of Langfang.The fourth part: using the shiftshare method it carries on the appraisal analysis of the existing economic structure, the superiority industry for Langfang from the view of the sustainable development. Through the analysis of these industrial comparison superiority theories, the goal is to discover the theory basis for the sustainable development of Langfang from the readjustment point of the economic structure.The fifth part: Proposing the sustainable development strategy and the countermeasure based on the economic structure optimization, the readjustment strategy of the economic structure suitable for the sustainable development of Langfang, and the operational strategy and the countermeasure for the society progresses, the resources and environment system and the human resources development and these are the core point of the article.
