In this study, we explored the spatial characteristics of housing prices, using spatial data on the average transaction price of Beijing’s housing blocks from 2005 and 2012, in order to reveal the factors influencing changes in housing price and address the way in which such changes in turn can affect land use, transportation, the living environment, and quality of life. The analysis revealed that the spatial autocorrelation effects associated with housing prices (and their increase) became significantly stronger between 2005 and 2012, especially in the central part of Beijing. Autocorrelation was, however, identified for both years. This finding explains the emergence of sub-area markets in recent years. It also provides evidence which suggests that developers or real estate agencies may have boosted housing prices purposely, which can lead to a biased market environment. Targeted policies are required in order to address, and avoid, this problem in the future. The spatial patterns of housing prices in different parts of Beijing were examined in detail. The differentiation of housing prices showed that Beijing has, in the past decade, gradually become a polynuclear city. By comparing the data for the two years using a multivariate linear regression model, the factors influencing housing price growth were analyzed. Besides location and the environment, it was found that housing policies related to property rights, the construction of the transportation network, and population change all played a key role in explaining changes in the spatial pattern of housing prices in Beijing in recent years. ===== PAGE 1 (score 7, numeric-paren 0, table-words 0, var-words 7) ===== 46 International review for spatial planning and sustainable development, Vol.2 No.3 (2014), 46-62 ISSN: 2187-3666 (online) DOI: http://dx.doi.org/10.14246/irspsd.2.3_47 Copyright@SPSD Press from 2010, SPSD Press, Kanazawa The Transitional Spatial Pattern of Housing Prices in Beijing: Factors and Implications Fang Wang1, 2 and Xiaolu Gao1* 1 Key Laboratory of Regional Sustainable Development Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences 2 University of Chinese Academy of Sciences * Corresponding Author, Email: gaoxl@igsnrr.ac.cn Received 23 August, 2013; Accepted 24 Feberuary 2014 Keywords: Housing Price, Spatial Autocorrelation, Spatial Structure, Beijing Abstract: The shift from the free-allocation housing welfare system to a market system was one of the most important parts of the economic system reform implemented in China from 1998 onwards.

INTRODUCTION The top priority for every family, housing constitutes an issue that is also relevant to the welfare, social stability, and economic development of a nation. From 1998 onwards, China has undergone intense urban housing system @Licensee SPSD Press This open access article is published under a Creative Commons [Attribution- NonCommercial-NoDerivatives 4.0 International] license. https://creativecommons.org/licenses/by-nc-nd/4.0/ ===== PAGE 13 (score 23, numeric-paren 0, table-words 7, var-words 6) ===== 58 IRSPSD International, Vol.2 No.3 (2014), 46-62 4.2 Linear regression model This study used a semi-log linear regression model, which has a better imitative and interpretation quality. Regression analysis was conducted, and multicollinearity detected by a stepwise regression technique (significance level is 0.05) in the SPSS16.0 (Table 5 and Table 6) using the data from 2005 and 2012, respectively. The results show that 13 variables entered the model in 2005 and 14 variables in 2012. Whilst both models have good explanatory power (adjusted R2=0.771 in 2005, adjusted R2=0.549 in 2012), the imitative quality was found to be better in 2005 than in 2012, probably because the influencing factors were more complicated in 2012. Not all the variables entered into the model in 2005 had strong multicollinearity. In 2012, the three property levels in the variables had good multicollinearity. However, through testing – by changing the variables randomly in the model – the three property types were all found to have strong significance and their regression coefficients were found to change little. As such, the models are considered reliable. Table 5. Regression results of housing price in 2005 B Std.

This study found that the housing price decreased as distance to the urban center increased; as such, prices obeyed the rent distance attenuation law. A 1-km increase in the distance to the urban center was found to lead to a 1.1% decrease in price per square meter in 2005 and a 1.6% decrease in 2012, respectively. At the same time, the variable describing the distance to the nearest sub-center also exerted a powerful, negative influence on housing prices in both of the years studied. Furthermore, the influence coefficients for the sub-center variable were greater than those generated by the urban center variable, indicating that sub-centers exert greater influence than the urban center, and thus that the polycentric pattern of Beijing has, at least initially, now been established. In addition, variables relating to transport convenience within the location characteristics were also found to have a significant and positive impact on housing prices. The variables relating to the proximity of a subway station and to the number of bus stations were both approved in a significance test for both of the years studied. Holding all other conditions the same, the unit housing prices of housing blocks that have a subway station within 1500 m were found to be about 3.9% and 3.8% higher per square meter in 2005 and 2012, respectively, than those without a subway station (we used the subway station plan to 2015 for the 2012 subway station data). Further, each additional bus station was found to raise the housing price by 0.6% per square meter in 2005 and 0.2% in 2012. Convenient transport access is good for trade development and population centralization; as such, it will stimulate the development of commercial housing. Transport will also directly influence the level of convenience experienced in people’s daily life – for instance, commuting and shopping, constituting a significant factor to consider when residents purchase houses.
