摘要:以信贷紧缩作为反映资金供给变化的外生冲击, 以有息资产负债率作为资本结构的代表指标,基于部分调整模型,引入双重差分变量,结合2000~2011年在中国境内上市的91家房地产公司的数据,研究信贷紧缩对我国房地产上市公司目标资本结构的影响。实证结果表明:信贷紧缩发生时,房地产上市公司目标有息资产负债率将降低;相比大公司、国有公司和抵押担保能力强的公司,小公司、民营公司以及抵押担保能力弱的公司在信贷紧缩期间,其目标有息资产负债率降低幅度更大。

Abstract: Credit squeeze is utilized as an exogenous shock reflecting the variation of capital supply and interestbearing debt ratio is proposed as representative indicator for capital structure. With the data from 91 real estate listed companies in China during 2000~2011, an econometric model based on standard partial adjustment model and differenceindifferences variable is introduced to empirically analyze the impact of credit squeeze on target capital structure for real estate listed companies. The results show that the target interestbearing debt ratio of real estate listed companies will decrease when credit squeeze occurs; the target interestbearing debt ratio in small companies, Privateowned Enterprises and the companies with weak mortgage capability decrease more than those in large companies, Stateowned Enterprises and the companies with strong mortgage capability.
Key words: credit squeeze; target capital structure; real estate listed companies
1引言
经典的资本结构理论主要基于融资需求而建立,通常隐含资金供给不受限制的假设,认为企业的融资决策由自身发展和投资需求所决定,不受资金供给面的影响。然而在现实经济中,公司资金供给可能受到各种因素的制约,公司融资决策是资金需求和供给两方面因素共同作用的结果[1]。作为限制资金供给的重要手段之一,信贷紧缩对资本结构的影响引起了学术界的关注。
目前关于信贷紧缩对资本结构的研究主要集中在现实资本结构层面[2,3],没有涉及对目标资本结构的讨论。目标资本结构又称最优资本结构,能使企业在一定时期内资本成本最低且企业价值最大。研究信贷紧缩对现实资本结构的影响,有助于了解资本结构的客观变化规律。……
