【摘要】：迄今為止，中國房地產(chǎn)行業(yè)經(jīng)歷了30多年的發(fā)展歷程，其發(fā)展模式實(shí)現(xiàn)了從計(jì)劃體制到市場制度的轉(zhuǎn)變，但無論房地產(chǎn)行業(yè)在發(fā)展中處于何種階段和運(yùn)行模式，始終離不開國家、政府的調(diào)控行為。1998年以前，國家對(duì)住宅實(shí)行福利分房的計(jì)劃經(jīng)濟(jì)制度，房改以后，住宅作為房地產(chǎn)行業(yè)的主體結(jié)構(gòu)走向了市場，其發(fā)展迅猛，市場運(yùn)行劇烈波動(dòng)，體現(xiàn)在價(jià)格波動(dòng)巨大，投資、投機(jī)活動(dòng)頻繁等，直接或間接的影響著國民經(jīng)濟(jì)的運(yùn)行和穩(wěn)定，因此加強(qiáng)房地產(chǎn)市場的監(jiān)管對(duì)經(jīng)濟(jì)社會(huì)中的各個(gè)角色尤為重要。 在上述背景下，本文開展了關(guān)于房地產(chǎn)市場預(yù)警系統(tǒng)建模與分析的研究，首先閱讀了大量文獻(xiàn)，了解到國內(nèi)外有關(guān)房地產(chǎn)市場監(jiān)管和預(yù)警的現(xiàn)狀，著重介紹了幾個(gè)典型代表國家的房地產(chǎn)市場監(jiān)管體系和國內(nèi)房地產(chǎn)預(yù)警研究的進(jìn)展，為找到合理的預(yù)警方案奠定了基礎(chǔ)；其次，本文闡述了房地產(chǎn)周期理論、房地產(chǎn)預(yù)警理論和要素、房地產(chǎn)市場波動(dòng)成因理論，然后將經(jīng)濟(jì)學(xué)原理和房地產(chǎn)行業(yè)相結(jié)合，為下文指標(biāo)的選取等后續(xù)工作奠定了理論基礎(chǔ)。 本文最終選取的是基于神經(jīng)網(wǎng)絡(luò)的房地產(chǎn)市場預(yù)警手段,首先介紹了預(yù)警建模需要的準(zhǔn)備工作，即數(shù)據(jù)預(yù)處理，包括采用時(shí)差分析篩選指標(biāo)和警情警度的數(shù)值定義、區(qū)間劃分；其次，選取BP神經(jīng)網(wǎng)絡(luò)算法，詳細(xì)介紹了算法原理和應(yīng)用算法建模的各個(gè)步驟環(huán)節(jié)，實(shí)現(xiàn)了BP神經(jīng)網(wǎng)絡(luò)與預(yù)警系統(tǒng)建模分析相結(jié)合,為實(shí)證分析的進(jìn)行做了原理性論述。 本文選取了天津市房地產(chǎn)市場為樣本進(jìn)行了實(shí)證分析，首先介紹了選取天津市作為樣本城市和劃分指標(biāo)時(shí)間區(qū)間的依據(jù)，描述了天津市房地產(chǎn)行業(yè)的發(fā)展歷程；其次，通過查詢了天津市統(tǒng)計(jì)年鑒和天津市統(tǒng)計(jì)局網(wǎng)站，獲得了天津市房地產(chǎn)預(yù)警指標(biāo)的詳細(xì)數(shù)據(jù)，確保了數(shù)據(jù)的真實(shí)性和準(zhǔn)確性；最后，對(duì)數(shù)據(jù)進(jìn)行數(shù)據(jù)分析和處理，篩選了天津市房地產(chǎn)市場預(yù)警指標(biāo)，運(yùn)用BP神經(jīng)網(wǎng)絡(luò)進(jìn)行建模，借助MATLAB軟件編程，，實(shí)現(xiàn)了BP神經(jīng)網(wǎng)絡(luò)的訓(xùn)練和參數(shù)的確定，并預(yù)測了2012年天津市房地產(chǎn)市場的警情，得出了市場運(yùn)行為“熱”的結(jié)論。 文章最后，總結(jié)了本文的研究成果和結(jié)論，著重分析了預(yù)警系統(tǒng)中的不足，對(duì)未來的研究方向進(jìn)行了展望，對(duì)今后預(yù)警研究的發(fā)展從制度角度提出了一些政策性建議。
[Abstract]:Up to now, China's real estate industry has experienced more than 30 years of development, its development model has realized the transformation from the planning system to the market system, but no matter what stage and operation mode the real estate industry is in the development, Before 1998, the state implemented the planned economy system of housing welfare and divided housing. After the housing reform, housing as the main structure of the real estate industry went to the market, and its development was swift and violent. The fierce fluctuations in market operation are reflected in the huge price fluctuations, frequent investment and speculative activities, which directly or indirectly affect the operation and stability of the national economy. Therefore, strengthening the supervision of the real estate market is particularly important to the economic and social roles. Under the above background, this paper has carried out the research on the modeling and analysis of the real estate market early warning system. First of all, it has read a lot of literature and learned about the current situation of the real estate market supervision and early warning at home and abroad. This paper mainly introduces several typical real estate market supervision systems and the progress of domestic real estate early warning research, which lays the foundation for finding a reasonable early warning scheme. Secondly, this paper expounds the real estate cycle theory. The theory and elements of real estate early warning, the theory of cause of real estate market fluctuation, and the combination of economic principle and real estate industry lay a theoretical foundation for the following work, such as the selection of indicators. This paper finally selects the real estate market early warning means based on neural network. Firstly, the paper introduces the preparation work needed for early warning modeling, that is, data preprocessing, including the numerical definition of time difference analysis screening index and alarm degree, interval division; Secondly, the algorithm of BP neural network is selected, the principle of the algorithm and the steps of applying the algorithm modeling are introduced in detail. The combination of BP neural network and early warning system modeling and analysis is realized, and the principle of the empirical analysis is discussed. This article selected Tianjin real estate market as the sample to carry on the empirical analysis, first introduced the Tianjin city as the sample city and the division index time interval basis, described the Tianjin real estate industry development course; secondly, By querying Tianjin Statistical Yearbook and Tianjin Bureau of Statistics website, the detailed data of Tianjin real estate early warning index are obtained to ensure the authenticity and accuracy of the data. Finally, the data are analyzed and processed. The early warning index of Tianjin real estate market is screened, the model is modeled by BP neural network, the training and parameter determination of BP neural network are realized by MATLAB software, and the warning situation of Tianjin real estate market in 2012 is predicted. The conclusion that the market is running as "hot" is concluded. Finally, this paper summarizes the research results and conclusions of this paper, focuses on the analysis of the shortcomings of the early warning system, prospects for the future research direction, and puts forward some policy suggestions for the future development of early warning research from the perspective of the system.
