中国房地产价格周期波动与成因研究.docx

摘 要
20 世纪 80 年代以来，全球房地产市场接连发生了膨胀与紧缩的巨大波动。我国房地产
市场以 1987 年为起点，1998 年才完全实现市场化分配，短短的二十几年间房价在波动中急
剧膨胀。尤其是 2003 年以后，大部分城市房价持续高涨，引发了对房地产泡沫的巨大争论。
2008 年国际金融危机前后，房价短期经历了大涨大跌的剧烈波动，与之相伴随的是对房地产
价格一系列调控政策的出台。从一些发达国家的历史经验来看，房价的波动给宏观经济稳定
带来了巨大的威胁，甚至导致了长时间经济萧条，这对市场调控与监管提出更高的要求。我
国的市场调控经验表明，仅仅使用货币政策的市场效果不明显，不得不采取直接行政干预措
施。而这些措施的合理性一直是理论界争论不休的问题。
论文通过房地产价格周期测度与解读、与国外房地产周期比较、分析房地产周期与宏观
经济、股市周期和通货膨胀周期的关系，对房地产价格周期波动特征做出具体的刻画，归纳
了关于房价周期波动特征的典型事实。结果表明，我国房价周期波动频率高、波动幅度大。
房价中期具有上涨刚性，不存在明显的中周期。房价周期、消费物价周期和股价周期之间存
在一定的领先滞后关系。在宏观经济中的行业定位、政策导向与房价之间也存在显著的相关
性。
论文分析了我国房价周期增长和波动的成因。房地产价格的持续上涨主要受到体制创新、
经济增长、工业化和城市化进程、流动性过剩几方面因素的影响。
基于房地产定价模型，论文提出实现房价周期波动的三个假设：假设一：消费者根据房
地产市场价格和理论价格之间的权衡进行购房决策，市场价格与理论价格之间存在互动关系，
导致房价周期性波动；假设二：信贷的扩张与紧缩对房地产业与非房地产业投资的影响产生
周期波动；假设三：金融自由化进程中伴随着增长过快的货币供给，加速了房价上涨趋势，
也为市场带来不确定性。
从实证结果来看，利率变化对房价的影响很小，无法与理论分析相一致，房价周期波动
的利率调整机制失灵；银行信贷与价格周期存在稳定的一致性，银行信贷对价格周期的影响
小于货币供给。货币供给弹性在 1998 年最高，到 2005 年达到最低值，2005 年以后货币供给
对房价增长的推动作用增强。货币供给对价格的影响大于对投资的影响，说明资金通过房地
产开发投资之外的途径直接对价格产生影响。
本文认为，1998 年以前，市场环境不稳定是周期波动频繁的主要原因；1999 年至 2005
年利率稳定、供求关系平衡，市场处于短暂的过渡期；2005 年以后房价周期波动频繁而剧烈，
周期表现出明显的外生性，论文重点分析了这个阶段房价周期的原因。II
2005 年以后，购房者购房动机发生了由居住到投资的转变，对于市场行为的解释需要突
破房地产供给需求局部均衡的框架，在与宏观经济结构相关的一般均衡框架内分析。在低利
率的条件下，购房者具有强烈的购房动机，房价具有上涨刚性，由市场价格与理论价格之间
动态变化形成的价格周期性下行的机制无法实现；利率失灵加剧了实体经济和房地产价格趋
势的背离，使房地产与实体经济的结构性失衡恶化，二者之间相对价格的变化机制无法实现；
中国特色的货币政策传导渠道使房价周期产生强烈的政策性或者外生性，在房价上涨阶段银
行自主信贷约束动机弱化，房价周期无法以银行信用自住紧缩为内在机制形成；2005 年以后
的价格波动频繁，是由于在利率失灵条件下，房价变化对利率的弹性减少，对广义货币量的
弹性增加，市场稳定性降低，价格容易受到流动性冲击。
房价在缺乏利率弹性前提下的上涨产生两个重要的后果：首先导致无房者的福利相对下
降；其次是银行风险积累。
论文回顾和评价了房地产市场调控的历程。低利率和流动性问题外生于房地产行业，与
货币政策和宏观经济环境密切联系，却成为影响房价正常波动的重要的内在原因。在这样的
情况下，如果仅仅着眼于针对房地产行业的局部调控，问题根本却出在经济全局，短期行政
措施也难以产生长期持续的效果。在现阶段，稳定预期是主要的房地产调控政策。对房地产
周期波动，主要控制由于银行信贷带来的金融风险。
最后提出主要结论和政策建议。长期而言，构建具有合理定价机制的房地产市场是我国
房地产业发展的必然选择，制度建设是长期稳定发展的基础。提出推进金融体系改革和利率
市场化、发展和完善房地产市场、增加金融供给稳定长期投资、推进房产税改革等几个方面
的政策含义。

Abstract
Since the 1980s, the global real estate market has been a spate of large fluctuations of the
expansion and contraction. China's real estate market started in 1987 and finished the
market-oriented distribution in 1998. In a short period of twenty years house prices expanded
rapidly in the fluctuations. Especially after 2003, most urban housing prices continued to rise,
triggering a huge debate on the real estate bubble. During the 2008 financial crisis, prices
experienced short-term volatility fluctuation,in hand with a series of regulatory policies on real
estate prices in China. From the historical experience of some developed countries, the volatility of
house prices brought about a huge threat to macroeconomic stability and even leaded to a prolonged
recession. This put higher demands on market regulation and supervision. China's experience in
market regulation shows that the effect of mere use of monetary policy on the market is not obvious.
The government had to take direct administrative interventions. The rationality of these measures
has been the vexed issue of the theoretical circle.
Focusing on China's real Prices estate cycle, the thesis analyzes the theoretical and empirical
intrinsic links between these phenomena.
The thesis measured and interpretated the real estate price cycles, compared with foreign real
estate cycle, analyzed the relationship between real estate cycle, macroeconomic, stock market
cycles and inflation cycle, made specific characterization of the characteristics of fluctuations in the
real estate price cycles, summarized typical facts on the characteristics of price cycles fluctuations.
The results show that China's housing prices have high frequency of cyclical fluctuations. Prices
rises rigidly, the mid-cycle does not exist., There are leading and lag relationships between the Price
cycles, consumer price cycles and the stock price cycles. There is a significant correlation between
the positioning of the real estate in the macroeconomic policy and prices.
The paper analyzes the causes of growth and volatility of China's housing prices cycle. Real
estate prices continue to rise by institutional innovation, economic growth, industrialization and
urbanization, excess liquidity factors. The paper established a general equilibrium-cycle model with
consumption habit formation and capital adjustment costs, explained that the price fluctuations are
caused by the mechanism of micro-investment and consumer behavior. Higher real estate
consumption habit formation makes the representative family transforms smaller fluctuations of the
marginal utility of real estate into larger price fluctuations. Due to the presence of adjustment costs,
investment fluctuations lead to price fluctuations. When the total output changes, the representation
family tends to change it into the variation in investment rather than current consumption changes.
Interest rates, credit growth, money supply have an important influence on the fluctuations in
the price cycle. They also lead to cyclical fluctuations of the real estate industry in recent years.IV
On the basis of theoretical analysis, the paper established a varying parameter model to analyze the
interaction between interest rates the credit, investment and money supply and real estate price
cycles in the different stages. From the empirical results, the impact of changes in interest rates on
house prices is very small. This isn’t consistent with the theoretical analysis. The interest rate
adjustment mechanism in prices cycle fluctuations failure. There is a stable consistency between
bank credit and price cycles. The impact of bank credit to the price cycle is less than the money
supply. Elasticity of money supply is the highest in 1998 and reached the lowest value in 2005.
After 2005 the money supply played enhanced role in promoting the growth in house prices. Money
supply’s impact on prices is greater than the impact on investment funds by way outside of the real
estate investment.
Therefore, we believe that our long-term real interest rates are low and this brought strong
upward momentum to house prices. Under low interest rates, the bank's real estate allocation of
credit resources lacks of capital cost constraints. The dynamic adjustment mechanism between the
real estate industry and other industries lack bank credit as an intermediary. The small changes of
interest rates at a low level make too small changes to investor decisions to make a substantial turn
in the market so that fluctuations mechanism in the price cycle can not be achieved. This is why the
real estate regulation adopted direct administrative control measures. If the interest rate under the
long-term control can not reach the equilibrium interest rate where the money supply and demand
are equal, the price fluctuations will lose stable base. Price fluctuations after 2005 is, the results of
the liquidity shock in the interest rate failure conditions. Currency by resident investments, hot
money and bank credit channels put impact on the real estate market led to a substantial increase
in short-term fluctuations.
High prices under the lack of interest rate elasticity have two important consequences. First,
this led to the welfare of those without housing relatively declined. Due to the price continued to
rise rapidly with lack of interest rate elasticity , the behavior of buyers lacked the cost constraints,
the initial allocation of housing wealth and income-determined housing affordability are the main
constraints of the housing investment decisions. Rising house prices cycle resulted in the the
relative welfare gap between housing and no housing continued to widen. The bank risk is
accumulated. Weakening of the investment cost constraints, the credit risk of banks is difficult to
accurately assess. Once the real interest rates rise, the cost of capital constraints of borrowers
strengthened, the potential risks of the bank exposure and may pose a threat to financial stability.
The paper reviewed and evaluated the course of the real estate market regulation. With the lack of
flexibility of real estate price changes, the market is in serious lack of stability and vulnerable to the
impact of the potential supply of money under certain conditions. In this context, the response of theV
real estate market for short-term government intervention is often excessive, The price either rose
too fast or falled back too excessively. Stable expectation is the main real estate control policy
options at this stage. With regard to fluctuations in the real estate cycle, the policy should mainly
control the financial risks due to bank credit.
Finally, the paper put forward the main conclusions and policy recommendations. In the long
run, building a real estate market with a reasonable pricing mechanism is the inevitable choice of
China's real estate development. Institution building is a long-term and stable basis for the
development. We should push forward the development of financial system reform and interest rate
markets, improve the real estate market, increase the financial supply, stabilize long-term
investment, and promote property tax reform as the main institution construction measures.
