| 摘 要： | 基于密度依赖理论及其分析方法,研究建筑企业死亡率密度依赖过程及其影响因素,并以江苏省建筑企业1989--2007年数据为例,建立企业一年数据结构,运用Cox比例风险模型进行实证分析.研究结果表明,产业层面的演化过程对建筑企业的死亡具有显著影响,但这种影响并不符合一般产业中密度依赖模型所得出的结果.种群密度对建筑企业死亡率的影响主要表现为随种群密度的增大而不断上升,但这一过程也同时受到组织年龄的影响.除此之外,建筑企业规模、宏观环境因素等也对企业死亡率有影响作用. |

| Abstract: | Based on the theory of density dependence,the factors and their effect on the mortality of the construction companies were identified.Taking the Jiangsu Province(1989-2007) as a practical case,a company-year data structure was established and the Cox proportional hazard model was used to analyze the mortality process.It is concluded that the construction industry level evolution plays an important role on exit rate of construction companies,however,this effect does not conform to density dependence as expec... |
