費率自由化對產險業經營效率與生產力影響之分析An Analysis of Rate Deregulation Affects Efficiency and Productivity

摘要
本文之研究目的在於探討保險費率自由化對於產險業經營效率與生產力變動的影響，利用資料包絡分析法進行實證分析，研究期間為1998年至2007年，並利用Malmquist指數衡量產險業之生產力變動。實證結果顯示費率自由化政策並沒有改善產險業經營效率，甚至在費率自由化後，產險業經營效率值反而呈現下降的趨勢。有關於影響產險業經營效率因子部份，實證結果顯示管理能力、資產規模與市占率與經營效率為正向關係，但資本資產比則為負向相關。

Abstract
The purpose of this study is to investigate the rate deregulation affects efficiency and productivity change in non-life insurance industry over the period 1998 to 2007. Using Data envelopment analysis and Malmquist index to measure insurers’ efficiency and productivity change. This result finds that rate deregulation not effect on improve insurers’ efficiency, even though the insurers’ efficiency is decreasing after rate deregulation. Relative to the determinants of insurers’ efficiency, the results shows that the relationship between efficiency and managerial ability, asset size and market share are significantly positive (except with market share), but the coefficient of capital-asset rate is negative.
