Policy spillover and regional linkage characteristics of the real estate market in China's urban agglomerations

The main purpose of this study is to determine the spillover effect of real estate regulatory policies released by core cities on the surrounding cities in major urban agglomerations based on regional linkage characteristics of China's real estate market. In this study, real estate transaction data of 157 cities were selected from 11 major urban agglomerations. Agglomeration's housing transaction volatility and spillover effect caused by the core city's regulatory policies were simulated by integrating spatial and temporal analysis model, event analysis, and symbolic time series analysis. The findings showed that (1) the regional linkage of the real estate market in the Harbin–Changchun and Middle–South Liaoning, Middle Reaches of the Yangtze River, Yangtze River Delta, Pearl River Delta, and West Side of the Straits agglomerations were remarkably tight and the core cities' policy spillover effect was significant, of which the house purchase limitation and credit limitation policies had the widest influence; (2) the regional linkage of the real estate market in the Beijing–Tianjin–Hebei agglomeration, Shandong Peninsula, Guanzhong Plain, and Chengdu–Chongqing agglomerations was relatively weaker, but the core cities' policies of market regulation and taxation had certain spillover effect; (3) there were significant differences in the spillover effects of different types of policies in different urban agglomerations; (4) generally, the core cities' policy spillover often reduced the changing characteristics of the real estate market and made it more ordered with more certainty in the whole agglomeration, with the exception of the Beijing–Tianjin–Hebei, West Side of the Straits, and Chengdu–Chongqing agglomerations.     

信贷供给、资产配置及企业绩效——来自中国制造业上市公司的证据

近些年,中国“金融与实体经济”的研究愈发成为热点。宏观层面,资金“脱实入虚”“金融空转”的讨论亦此起彼伏。然而,针对微观层面的企业资金“脱实入虚”的研究则寥寥无几。本文选取2003—2016年中国A股制造业上市公司的年度报告数据,利用2009年宏观调控措施营造的“准自然实验”环境,采用双重差分方法探究在资金资源充足的前提下,企业配置金融资产的倾向性,并进一步研究企业绩效的后续变化情况。实证结果表明,当制造业企业获得更多的信贷资金支持,同时缺乏有效的外部监管时,企业更倾向于配置金融资产,金融活动也会在企业的日常生产经营中扮演愈发重要的角色。在此基础上,企业的主营业务却未得到发展,反而盈利能力、成长能力均受到损害,且后者受到的影响更大,即进行过多金融投资对中国A股制造业上市公司的远期影响更为深重。基于上述结论,本文从实体经济从业者、资金提供方以及监管层三个角度提出了相关政策建议。     

Price competition in the spatial real estate market: allies or rivals?

This paper examines whether real estate firms can avoid price competition when properties in the vicinity are priced by allies. An oligopoly model with differentiated products generally suggests that real estate firms engage in price competition with their spatially closest rivals. Yet, they can raise property prices when the market share of their allies increases. To test this prediction, a spatial autoregressive model with spatial autoregressive disturbances, including a share of allies in the vicinity, is estimated using data on the prices of residential condos in central Tokyo, Japan. The model prediction is supported by the empirical results. In the data set, the magnitude of the market share on property prices increases with the expansion of the size of the spatial market.     

中国大中城市商业地产开发环境评价——基于时序全局主成分分析

2007年爆发的金融危机不但改变了全球经济格局,也增加了中国房地产市场的不确定性因素。随着住宅开发的竞争越来越激烈,其利润率呈现走低趋势。越来越多的房地产开发商从住宅地产转向商业地产领域,以期获得更加丰厚的回报。选取中国35个大中城市的42个变量共计近6000个数据,利用时序全局主成分分析法对后金融危机时期的这些城市商业地产开发环境进行了系统研究,建立了比较科学的评价指标体系。     

A novel approach to legacy donations with long-term benefits supported by numerical illustrations

Philanthropic donors face challenges in matching the causes to which they donate, the time horizon—and thus impact—of their donations, and the charitable vehicles they choose for making contributions. Wealthier donors may elect to create their own foundations and customize their charitable support. Less wealthy donors have limited choices: they may contribute to a nonprofit's current operations or to existing nonprofit endowments. We present a novel approach for making charitable donations, blending aspects of each of these strategies. Our approach has potential long-term financial benefits, allows donors to control their charitable donations in a convenient and easy-to-implement manner, can be established through an existing nonprofit organization, expands opportunities for more donors because it requires a smaller corpus contribution with lower management costs than creating a foundation, provides tax savings in the United States and other countries (e.g., the UK, Canada, and Australia) comparable to other planned giving vehicles, and may be implemented during one's lifetime using donor advised funds or as part of a legacy plan through the donor's estate documents, which is when the long-term benefits accrue.

近代上海房地产市场波动的金融分析(1929～1935)

1929~1935年,上海房地产市场在短短的五六年间经历了暴涨和暴跌。文章通过对房地产市场的金融分析,发现导致上海房地产市场在短期内大起大落的主要原因是币值和物价的变化。由于近代币值和物价的变化,结果导致货币市场上流通量发生剧烈波动,并影响了房地产市场的投机需求,导致房地产市场大起大落。这也提醒人们在分析房地产市场价格时要注意币值及物价对供求关系的影响,注意甄别各种不同的需求及其比重。     

Real estate markets and the macroeconomy: A dynamic coherence framework

This paper analyzes the dynamic interactions between real estate markets, in the US and the UK and their macroeconomic environments. We apply a new approach based on a dynamic coherence function (DCF) to study these interactions bringing together different real estate markets (the securitized market, the commercial market and the residential market). The results suggest that there is a common trend that drives the different real estate markets in the UK and the US, particularly in the long run, since they have a similar shape of the DCF. We also find that, in the US, wealth and housing expenditure channels are very conductive during real estate crises. However, in the UK, only the wealth effect is significant as a transmission channel during real estate market downturns. In addition, real estate markets in the UK and the US react differently to institutional shocks. This brings some insights on the conduct of monetary policy in order to avoid disturbances in real estate markets.
