通过DEA方法对中国境内16家财险公司2006--2008年的技术效率、纯技术效率及规模效率及规模报酬形态分别进行了测度。结果表明,相比外资公司,中资公司在规模效率上有着很大的优势,而在纯技术效率方面所占的优势则不太明显。最后,从规模效率和纯技术效率两方面提出了提高中国财产保险公司效率的途径。     

基于三阶段DEA模型的中国保险业效率测评研究

本文运用三阶段DEA模型和基于新会计准则下的2007—2010年中国保险公司数据,分别对配置效率、技术效率、成本效率和收益效率进行实证评估。研究发现,中国寿险业和非寿险业的效率具有相似性:技术效率突出,配置效率和成本效率值不高,收益效率则较低。分类来看,国有保险公司收益效率较高,集团化保险公司技术效率突出,中资保险公司的配置效率、成本效率则较低。从技术效率前沿公司数量比例来看,寿险公司明显高于非寿险公司,非寿险公司更需要提高管理决策水平。

财产保险公司经营风险分析

财产保险公司是经营财产风险的商业性企业。作为微观的经济实体,财产保险公司在按照市场规则竞争和经营的过程中面对着诸多不确定因素。这些不确定因素的存在和相互作用给财产保险公司的经营带来了风险。又由于财产保险公司经营对象具有特殊性,使得财产保险公司的风险更为复杂。能否正确处理和控制风险。将直接影响财产保险公司的正常经营。加之,我国财产保险公司近年来在发展过程中已存在着不少风险隐患且逐年累积,如不及时加以控制和化解,     

财产保险公司经营风险分析

产保险公司经营涉及社会不同层次、千百万投保人和被保险人的经济利益。它集中了众多投保人的财产风险，并为个人，家庭、企业的财产安全提供经济保障，对维护家庭稳定和社会安定起着重要的作用，产险业在国民经济中凭借其雄厚的经济实力，为推动经济发展提供资金来源。如果忽视风险管理，一旦经营风险转化为损失，导致偿付能力弱化，不仅直接损害投保人的利益而且会危及财产保险公司自身的安全，进而将影响社会和经济的发展。为此，本文首先讨论了财产保险公司经营中存在的主要风险，接着分析了规避财产保险公司经营中存在的风险，最后做了总结。因此本文具有深刻的理论意义和广泛的实际应用。     

Financial liberalization and bank efficiency: a comparative analysis of India and Pakistan

This paper provides a comparative analysis of the evolution of the technical efficiency of commercial banks in India and Pakistan during 1988–1998, a period characterized by far-reaching changes in the banking industry brought about by financial liberalization. Data Envelopment Analysis is applied to two alternative input–output specifications to measure technical efficiency, and to decompose technical efficiency into its two components, pure technical efficiency and scale efficiency. The consistency of the estimated efficiency scores are checked by examining their relationship with three traditional non-frontier measures of bank performance. In addition, the relationship between bank size and technical efficiency is examined. It is found that the overall technical efficiency of the banking industry of both countries improved gradually over the years, especially after 1995. Unlike public sector banks in India, public sector banks in Pakistan witnessed improvement in scale efficiency only. It is also found that banks are relatively more efficient in generating earning assets than in generating income. This is attributed to the presence of high non-performing loans. In addition, it is found that the gap between the pure technical efficiency of different size groups has declined over the years.     

Regional technical efficiency and technology gaps in rural China: evidence from CHIP surveys

This paper uses household-level datasets called Chinese Household Income Project (CHIP) surveys to investigate the regional technical efficiency, technology gap, and their determinants in rural China. A metafrontier production function approach is employed to fit the values of the technical efficiency and the technology gap ratio of rural households in six regions of China. The findings indicate that the technical efficiency improved remarkably from 1988 to 2002, but the technology gap ratio among regions changed slightly in the same period. The findings also show a negative relationship between the technology gap ratio and the regional technical efficiency for all regions except the northwest that has the lowest value of both the technical efficiency and the technology gap ratio. Next, the Tobit model is employed to discern the sources of efficiency and technology gaps. The results show that quality of agricultural labor, agricultural infrastructure, natural conditions, and farmer's political status have significant effects on farms' technical efficiency and technology gap ratio.     

Measuring technical efficiency in the Greek agricultural sector

This paper measures the degree of technical efficiency of Greek farms at discrete points in time. Stochastic frontier production functions are estimated from four annual Farm Accountancy Data Network (FADN) surveys of the 1992–1995 period. From the results, a measure of technical efficiency is calculated for each farm for each year. The four distributions of technical efficiency values are examined and compared. All four samples show a wide range of farm-specific technical efficiency but efficiency is improving over the period. The paper also presents frontier estimates for small and large farms classified according to economic size. In that case, technical efficiency measures are calculated and their distributions are examined and compared. The results show that large farms are more efficient than small farms. However, efficiency is improving in both size farms over the period. In general, the results of this study indicate that there is substantial scope for improving technical efficiency of Greek farms.

Assessing the impact of economic liberalization across countries: a comparison of dairy industry efficiency in Canada and the USA

This paper examines and compares the technical efficiency measures of Ontario and New York dairy producers for the period 1992 to 1998. A nonparametric stochastic frontier model is introduced to estimate technical efficiency. The backfitting algorithm of Breiman and Friedman is used to estimate the frontier. Empirical results indicate that during the period of study, New York dairy farmers produced milk more efficiently than Ontario dairy producers, but the magnitude of the difference was small. The estimated mean technical efficiency for the former group is 0.602 as compared to 0.532 for the latter. The results also indicated that over time, dairy farms in both regions improved their level of technical efficiency. Furthermore, no correlation was found between farm size and estimated technical efficiency.     

我国工业行业全要素生产率变动分析

基于2006—2009年我国工业行业的面板数据,采用非参数Malmquist指数分析法,对我国工业的全要素生产率变动情况进行了实证研究,并将其分解为技术进步、纯技术效率和规模效率。结果表明:2006—2009年我国工业全要素生产率年均增长率仅为4.3%,技术进步年均增长率为1.6%,技术效率年均增长率为2.7%,技术进步已失去其推动全要素生产率增长的主导性优势地位;我国工业发展需注重同时提高技术效率和技术进步水平,否则全要素生产率增长会受到限制。     

Specification and estimation of stochastic multiple-output production and technical inefficiency

This paper presents a primal-based approach for specification and estimation of multiple-output production frontiers that allows simultaneous identification and estimation of determinants of technical inefficiency. The proposed model extends the technical efficiency effects model by Battese and Coelli (1995) to general multiple-output technologies. An empirical application using Swedish health care panel data from the years 1989–1994 is included. The key issue is to test for the effects on technical efficiency of an organizational reform implemented with the primary purpose to increase efficiency. The results reveal no significant effect on technical efficiency of the reform, but evidence of overall decreased technical efficiency and technical progress in the provision of health care over the studied time period are found.     

Economic openness and technical efficiency: A case study of Chinese manufacturing industries

This paper presents a study of the technical efficiency of industries in a transitional economy: China. Using data for 28 manufacturing industries across 29 provinces and the Data Envelopment Analysis approach, the technical efficiency of each industry is measured and compared across regions and provinces. The determinants of differential technical efficiency performance are analysed, with a particular focus on the impact of trade orientation and foreign investment. Trade openness is found generally to have a positive effect on technical efficiency.

Trade liberalization and technical efficiency in the Indonesian chemicals industry

This article examines the impact of trade reform on technical efficiency on the Indonesian chemicals industry using firm-level panel data. The effects of trade reform on technical efficiency are analysed using a stochastic frontier approach. Two variables represent trade reform in this model: effective rate of protection (ERP) and import ratio (IMP). The findings of the present study suggest that both trade reform variables have significant effects on technical efficiency. The coefficient of ERP has a positive sign and is statistically significant, which means that an increase in ERP increases the inefficiency (or decreases the technical efficiency) of firms in the chemicals industry. The coefficient of IMP is negative and statistically significant, which represents the negative impact of IMP on technical inefficiency (or positive on technical efficiency). Thus, trade reform, a reduction in ERP or an increase in IMP, has an unambiguously positive effect on technical efficiency in the Indonesian chemicals industry.
