青島市房地產(chǎn)市場(chǎng)預(yù)警系統(tǒng)建模及其實(shí)證研究

摘要

房地產(chǎn)業(yè)在整個(gè)國(guó)民經(jīng)濟(jì)體系中屬于先導(dǎo)性、基礎(chǔ)性產(chǎn)業(yè),處于主導(dǎo)產(chǎn)業(yè)地位,其存在著明顯的周期波動(dòng)規(guī)律。起伏過(guò)大的波動(dòng)與房地產(chǎn)經(jīng)濟(jì)的持續(xù)健康穩(wěn)定發(fā)展相矛盾,但是目前,我國(guó)房地產(chǎn)市場(chǎng)運(yùn)行機(jī)制不甚完善,還沒(méi)有形成合理、有序、競(jìng)爭(zhēng)、高效的市場(chǎng)運(yùn)行體系,房地產(chǎn)市場(chǎng)存在信息傳遞不暢、信息數(shù)據(jù)失真、市場(chǎng)行情展示手段落后和市場(chǎng)交易網(wǎng)絡(luò)封閉等?系列問(wèn)題。因此,研究房地產(chǎn)預(yù)警系統(tǒng),設(shè)置房地產(chǎn)預(yù)警指標(biāo)體系,系統(tǒng)、科學(xué)、準(zhǔn)確地確定房地產(chǎn)安全區(qū)域,成為有關(guān)決策部門亟需解決的重大現(xiàn)實(shí)問(wèn)題,又是學(xué)術(shù)界需要深入研究的重大理論問(wèn)題。

針對(duì)這種情況,本文提出了房地產(chǎn)市場(chǎng)預(yù)警系統(tǒng)模型研究,為促進(jìn)房地產(chǎn)業(yè)的健康發(fā)展提供一定的理論依據(jù)。并在此基礎(chǔ)上,對(duì)青島市房地產(chǎn)市場(chǎng)進(jìn)行了實(shí)證研究。

本文通過(guò)研究,得到的研究成果及研究結(jié)論主要有以下幾個(gè)方面:

(1)基于對(duì)國(guó)內(nèi)外房地產(chǎn)預(yù)警研究現(xiàn)狀的分析,歸納總結(jié)了房地產(chǎn)預(yù)警的基本概念、基本原則和基本方法。在對(duì)國(guó)內(nèi)原有各類房地產(chǎn)指標(biāo)體系進(jìn)行研究的基礎(chǔ)上,確定房地產(chǎn)預(yù)警指標(biāo)。

(2)房地產(chǎn)作為社會(huì)經(jīng)濟(jì)系統(tǒng)的一個(gè)子系統(tǒng),具有非線性復(fù)雜系統(tǒng)的特性。本文立足于解決房地產(chǎn)系統(tǒng)的非線性問(wèn)題,建立更為先進(jìn)科學(xué)的房地產(chǎn)預(yù)警系統(tǒng),避免房地產(chǎn)市場(chǎng)的非常態(tài)波動(dòng),促進(jìn)房地產(chǎn)市場(chǎng)的持續(xù)、健康、穩(wěn)定發(fā)展。在現(xiàn)有研究的基礎(chǔ)上,系統(tǒng)地分析了房地產(chǎn)預(yù)警的特點(diǎn)及功能特征,對(duì)房地產(chǎn)預(yù)警過(guò)程中的關(guān)鍵預(yù)警指標(biāo)進(jìn)行了辨識(shí)、預(yù)測(cè)、診斷、監(jiān)測(cè)和控制,構(gòu)建了具有理論性和實(shí)踐性的房地產(chǎn)預(yù)警系統(tǒng),為解決房地產(chǎn)預(yù)警問(wèn)題提供了依據(jù)。

(3)本文介紹的房地產(chǎn)預(yù)警系統(tǒng),以神經(jīng)網(wǎng)絡(luò)理論和房地產(chǎn)預(yù)警理論為基礎(chǔ),構(gòu)建了預(yù)警模型。利用神經(jīng)網(wǎng)絡(luò)在預(yù)測(cè)和模式識(shí)別領(lǐng)域的成熟運(yùn)用,重點(diǎn)探

討基于神經(jīng)網(wǎng)絡(luò)理論的房地產(chǎn)預(yù)警的模型和方法,并利用該模型形成了房地產(chǎn)市場(chǎng)預(yù)警體系。

(4)在建立了房地產(chǎn)預(yù)警指標(biāo)體系的基礎(chǔ)上,本文提出了基于LVQ—RBF神經(jīng)網(wǎng)絡(luò)的房地產(chǎn)預(yù)警模型,該模型克服了傳統(tǒng)預(yù)警方法的不足,具有高度的并行性和全局性,提高了房地產(chǎn)預(yù)警系統(tǒng)的非線性、自學(xué)習(xí)性、自適應(yīng)性及大規(guī)模并行分布知識(shí)處理的能力,具有較高的精確度和適用性。

(5)本文依據(jù)前期研究理論成果,對(duì)青島市房地產(chǎn)風(fēng)險(xiǎn)預(yù)警進(jìn)行實(shí)證分析,依據(jù)技術(shù)可能、經(jīng)濟(jì)合理、操作可行等原則,最終形成綜合預(yù)警分析結(jié)論。預(yù)警分析的結(jié)果與青島房地產(chǎn)發(fā)展的實(shí)際情況基本吻合,表明本項(xiàng)研究所建立的房地產(chǎn)預(yù)警模型系統(tǒng)有效可行,理論分析充分,實(shí)用價(jià)值高,為指導(dǎo)和調(diào)控房地產(chǎn)市場(chǎng)提供了科學(xué)依據(jù)。
