The Study Of Real Estate Ecosystem And Its Health Evaluation Index System

"food, clothing, housing and transportation" is necessary to every society and every individual. With the improvement of living standards, the problem of food and clothing has been basically solved Currently, "housing" has become the focus of attention by more and more people, you can hear it from frequently. From ordinary people's daily conversation to the subject of movies and television programs, to the National People's Congress on behalf of the questions. With the rising housing prices and the growth market speculation, how to keep real estate development health stable and sustainable is the problem which must be solved.This paper is based on the theory of ecological systems. Clear the real estate ecosystem boundaries. The concept of the real estate ecosystem is proposed by studying the relationship between the parties and the system, and constructing the health assessment index system of real estate ecosystem and evaluation model at the same time. It has some theoretical innovation, and practical significance of the real estate healthy development. Specifically, this article is based on the ecological perspective; studies of the natural ecological systems theory, proposed the concept of real estate stocks and real estate communities, analysis of the relationship between participants. With the theory of energy flow, clear the real estate ecosystem boundaries through financial flows, proposed the concept of the real estate ecosystems, and identify the real estate ecosystem structure. Then establish the real estate ecosystem health assessment index system, establish evaluation model by projection pursuit model forecasting result, in which the optimal projection direction was obtained based on real-rode genetic algorithm. This is integrated used of the ecological system theory, real estate economics, political economics, statistics, computing science theory and so on. At last, the analysis and suggestions of the real estate ecosystem of Chongqing.The content of this thesis:Firstly, analysis to determine the real estate ecosystem boundaries, concepts and structuresThis paper contains the studies of the natural ecological system theory. On the first place, proposing the concept of real estate stocks and real estate communities for the study of real estate to build a better system of stratification. With the theory of energy flow, classify the real estate ecosystem boundary based on the analysis of capital flows, then proposing the concept of the real estate ecosystems. Studying the real estate ecosystem relationships between participants, and the similarities and differences between the real estate ecosystem and natural ecosystems, identify the effect by the "government" to the ecological environment and the real estate ecosystem structure of the system.Secondly, the real estate ecosystem health assessment According to the health standard of the real estate ecosystem, proposing the ecosystem health assessment index system and determine the scope of each index value Que. the indicators which characterization of the real estate ecosystem health are a high-dimensional and nonlinear feature evaluation index system. Selecting the projection pursuit to dealing with the data. Estimate the optimal projection direction and the optimal value of the integrated features of established real estate ecosystem health. and build evaluation model.Thirdly, A Case Study,Analysis of the Real Estate situation in Chongqing, based on actual data evaluation of its real estate ecosystem health, and analyzed the evaluation results, proposed countermeasures. From the empirical point of view, the basic objective of reflecting the real estate problems and the results are obvious, to maintain the real estate ecosystem health, promote the eco-system balance is a major issue of the national economy and human health.But the real estate ecosystem is an open and dynamic system, the development of its health standards are changing frequently. Many problems will be studied further and resolved.
