摘要
基于2000年至2004年我国非寿险公司的数据,本文研究了我国非寿险业是否遵循Gibrat法则,即公司成长是否独立于规模。结果发现,我国非寿险业接受Gibrat法则。投入成本对公司成长的影响显著为负,高投入成本会阻止公司资产规模的增长;利润率对公司成长的影响不显著,没有证据表明利润对公司规模有显著的支撑或抑制作用;公司产出组合对成长存在较为显著的影响,业务的专业化经营,对公司的成长有益;所有制形式对公司成长的影响并不显著。
Based on the data of non-life insurance companies in China from 2000 to 2004, this paper investigate whether non-life insurance industry in China is consistent with Gibrat's law. In other words, is growth independent of size? We find, Gibrat's law is supported in non-life insurance industry. Input cost is significantly negative to growth, higher input cost can prohibit the growth of size ; Profitability is not significant, there is no evidence that profit has supporting or restraining effect on the company's size. The output mix is a little significant to growth, the specialization of operation is helpful to the growth. Ownership has no effect on the growth of companies.
