不同的历史条件下,房地产业发展的主导因素不同。由于常规分析方法对房地产业的发展动因的分析具有模糊性,本文给出了基于主成分回归的计量经济模型。该方法通过消除自变量之间的多重共线性,很好地克服了普通最小二乘分析在处理多重共线性上的缺陷,对房地产业经济增长因素进行可靠分析具有较强的现实意义。
Under different historical conditions,
the leading factors of the development of the real estate industry are
different. Because of the fuzziness of the conventional analysis method to the
analysis of the development cause of the real estate industry, this paper
presents the econometric model based on principal component regression. By
eliminating the complex multicollinearity among independent variables, this
method overcomes the defects of the ordinary least squares analysis in dealing
with multicollinearity, and has strong practical significance in the reliable
analysis of economic growth factors of the real estate industry.
