【摘要】:伴隨著市場經(jīng)濟的飛速發(fā)展,我國的房地產(chǎn)行業(yè)不斷呈現(xiàn)新跡象,住房價格經(jīng)歷一次又一次的上漲,中低收入家庭的基本住房需求越來越難以實現(xiàn),提高住房保障規(guī)模逐漸成為全社會的焦點。在住房保障的發(fā)展歷程中,我國已經(jīng)建立了廉租房、公共租賃住房、經(jīng)濟適用住房、限價房、棚改房的綜合保障體系。但是近年來,全國許多地區(qū)先后對如何實現(xiàn)最大住房保障效果進行了新的探索,如停建經(jīng)濟適用住房、加速建公共租賃住房以及“三房合一”等措施已運行于部分地區(qū)的住房保障中。然而,這些舉措可以歸結(jié)成二方面,即保障體系中各種類型的保障性住房是否都需要建設(shè)?若要建設(shè)則以何比例配建?因此,,本文嘗試從這二方面著手,站在政府的視角,研究保障房的配建結(jié)構(gòu)問題,試圖通過合理科學(xué)的確定保障房的配建結(jié)構(gòu),提高整體住房保障的效果。 縱觀國內(nèi)外研究成果,通過住房外部影響論、居住隔離論、可持續(xù)發(fā)展論的融合,深度剖析我國的住房保障問題,分析各保障性住房的特征、供需情況,全面權(quán)衡中低收入家庭對各保障性住房的需求“緩、急、輕、重”程度。為了滿足中低收入家庭對各保障房的需求程度,筆者從“成本—效用”二維角度考慮政府保障性住房的配建規(guī)劃,設(shè)想通過建立“成本—效用”指標體系,作為政府決策保障性住房配建結(jié)構(gòu)的理論依據(jù)。 本文深入了解影響我國保障房配建的主客觀因素,將政府確定保障房配建結(jié)構(gòu)歸結(jié)成一個決策問題,對比分析各決策方法優(yōu)缺點,選用熵權(quán)法為基礎(chǔ),并建立熵權(quán)系數(shù)優(yōu)化模型研究保障房的配建結(jié)構(gòu)。通過熵權(quán)計算法計算出“成本—效用”指標體系中的各指標熵權(quán)系數(shù),用熵權(quán)系數(shù)作為優(yōu)化模型目標函數(shù)系數(shù),再將影響政府保障房配建的強制因素反映于模型約束條件中,此模型全面覆蓋影響保障房配建結(jié)構(gòu)的強制性和柔性因素,為政府制定科學(xué)高效的保障房配建方案提供實踐參考。 通過熵權(quán)優(yōu)化模型對哈爾濱市保障房的配建結(jié)構(gòu)研究發(fā)現(xiàn),在“成本—效用”指標體系中,需求緊迫度對保障房的配建結(jié)構(gòu)影響最大,政府需充分重視需求緊迫度;模型優(yōu)化后的保障房配建結(jié)構(gòu)不僅是從配建比例上調(diào)整了原配建結(jié)構(gòu),而且從配建體制上也有新的創(chuàng)新。因此,政府可以從配建比例和配建體制上優(yōu)化保障房配建結(jié)構(gòu),實現(xiàn)住房保障的可持續(xù)演變,更快的提高住房保障效果。
[Abstract]:With the rapid development of the market economy, the real estate industry in our country has been showing new signs, housing prices have been rising again and again, the basic housing needs of low- and middle-income families are becoming more and more difficult to achieve.Improving the scale of housing security has gradually become the focus of the whole society.In the course of the development of housing security, China has established a comprehensive security system of low-rent housing, public rental housing, affordable housing, price limit housing, and greenhouse housing.However, in recent years, many regions throughout the country have made new explorations on how to achieve the maximum housing security effect, such as stopping the construction of affordable housing.Measures such as accelerating the construction of public rental housing and "three houses in one" have been used in housing security in some areas.However, these initiatives can be summed up in two aspects, that is, the security system in the various types of affordable housing needs to be built?What is the proportion of construction to be built?Therefore, this article tries to start from these two aspects, stands in the government's angle of view, studies indemnificatory apartment's construction structure question, attempts through the reasonable scientific determination indemnificatory apartment's matching structure, enhances the overall housing security effect.Through the integration of housing external influence theory, housing isolation theory and sustainable development theory, this paper makes a deep analysis of the housing security problems in our country, and analyzes the characteristics, supply and demand situation of all kinds of affordable housing, through the integration of housing external impact theory, housing isolation theory and sustainable development theory.Weigh all-round low-and-middle-income families on the demand for affordable housing "slow, urgent, light, heavy" degree.In order to meet the demand of indemnificatory apartment for middle and low income families, the author considers the construction planning of the government's affordable housing from the perspective of "cost-utility", and proposes to establish the "cost-utility" index system.As the theoretical basis of the construction structure of the indemnificatory housing.In this paper, we deeply understand the subjective and objective factors that affect the construction of indemnificatory apartment in our country, and make the decision on the construction structure of indemnificatory apartment by the government as a decision-making problem, and compare and analyze the advantages and disadvantages of each decision-making method, and choose entropy weight method as the basis.And set up the optimization model of entropy weight coefficient to study indemnificatory apartment's construction structure.The entropy coefficient of each index in the index system of "cost and utility" is calculated by the method of entropy weight calculation. The entropy weight coefficient is used as the objective function coefficient of the optimization model, and then the compulsory factors affecting the construction of government indemnificatory apartment are reflected in the constraint conditions of the model.This model comprehensively covers the mandatory and flexible factors that affect indemnificatory apartment's construction structure, and provides practical reference for the government to formulate scientific and efficient schemes for the allocation of indemnificatory apartment.Based on the entropy weight optimization model, it is found that in the "cost-utility" index system, the urgency of demand has the greatest impact on the construction structure of indemnificatory apartment, and the government should pay full attention to the urgency of demand.The model optimized indemnificatory apartment construction structure not only adjusts the original matching structure from the proportion of allocation, but also has a new innovation from the construction system.Therefore, the government can optimize the construction structure of indemnificatory apartment from the proportion and system of allocation, realize the sustainable evolution of housing security, and improve the effect of housing security more quickly.
