基于效率的长三角区域创新网络形成机理

在分析了长江三角洲区域创新网络的形成基础上,着重探索长三角区域创新网络非同质化实质和三个创新群的外溢效率内在的逻辑关系,从而构建了基于效率长三角区域创新网络形成内在机理的理论研究框架。长三角区域创新网络效率不仅限于“点”与“点”之间的外溢效应,而主要体现于更高层次“群”与“群”之间的外溢效应。     

中小板上市公司债务融资效率研究

基于江苏省20家中小板上市公司的面板数据,采用聚类和数据包络分析相结合的方法,对这些公司进行债务融资效率分析。研究表明,中小板企业在融入资产的配置效率方面更为关注自身盈利状况和成长前景,而没有充分认识到节约融资成本的重要性,从而导致企业债务融资效率偏低。对此,我国中小板企业应充分发挥债务融资的杠杆作用,优化资本结构,通过强强联合和以强带弱的途径分散经营风险,在扩大规模效益的基础上持续增强企业盈利能力。     

中国开放式基金运营效率的DEA分析

本文采用数据包络分析方法(DEA)对我国在2003年之前成立的17只开放式基金的相对运营效率进行实证分析。结果发现:债券型基金总体平均运营效率最高,表现稳健,而混合型基金效率一般,股票型基金介于两者之间;大部分基金由于风险控制能力较差,业绩波动太大,导致较低的运营效率。

风险投资企业治理模式比较及效率研究

风险投资企业的治理问题作为一个新兴的研究领域日益受到理论界和实践部门的关注。本文通过构建风险投资企业治理模式的简单模型,对三种典型的风险资本运作模式进行了比较和相应效率分析,提出我国风险投资企业应采取强制性制度变迁和诱致性制度变迁相结合的治理模式。     

论农村信用社的产权多元化

信用社有着自己的基本特征。中国农村信用社实践中存在三大误区:与集体经济相提并论;信用中介与一般中介特征相混淆;改革中出现行政化、机关化问题突出。因此,进行农信社的产权多元化是关键。本文分析的逻辑表明,我国农信社的改革应坚持两条道路,一是将多数农信社改造为商业银行;二是按照合作原则对部分农信社改造成真正意义上的信用社组织。     

The impacts of risk-taking behaviour and competition on technical efficiency: Evidence from the Chinese banking industry

This paper tests the impact of risk and competition on efficiency in the Chinese banking industry over the period 2003–2013. Comprehensive types of risk-taking behaviour are considered including credit risk, liquidity risk, capital risk, and insolvency risk. Competition is measured by the Lerner index. The results are cross-checked using an alternative econometric technique as well as an alternative competition indicator. The findings show that the technical and pure technical efficiencies of Chinese commercial banks are significantly and negatively affected by liquidity risk. They further show that greater competition precedes declines in technical and pure technical efficiencies of Chinese commercial banks. The results suggest that Chinese bank efficiency is significantly affected by bank diversification, banking sector development, stock market development, inflation and GDP growth rate. The findings also indicate that, compared to state-owned commercial banks, joint-stock commercial banks and city commercial banks have lower technical and pure technical efficiencies.     

Behind managerial reforms: the French experience

Inspired by new public management (NPM), managerial reforms in many countries from the 1990s onwards focused on three criteria: effectiveness, efficiency and enhancing service quality. These criteria were meant to be given equal weight in measuring performance, but this paper shows that some criteria dominated. The reform experiences of four countries are compared, with a focus on French reforms.     

An Application of the Dynamic Network DEA Model: The Case of Banks in Taiwan

ABSTRACT

In this study, we apply the dynamic network slack-based measure data envelopment analysis model (DNSBM) to measure the efficiency of Taiwanese banks during the period 2005–11. Using the network structure, we define intellectual capital creation capability as one of the production stages. In order to capture the dynamics of the transformation process, the nonperforming loans and loan loss reserves are defined as carryover items. This study offers sufficient information for managers to understand not only the overall performance of their banks but also the efficiency of each production stage and the dynamic changes of the overall and divisional efficiencies.     

Estimating input-mix efficiency in a parametric framework: application to state-level agricultural data for the United States

ABSTRACT

This paper contributes to the productivity literature by demonstrating novel econometric methods to estimate input-mix efficiency (IME) in a parametric framework. Input-mix efficiency is defined as the potential improvement in productivity with change in input mix. Any change in input-mix (e.g., land to labou r ratio) will result in change in productivity. The advantage of this approach is that it does not require data on input prices to estimate the mix efficiency levels. A nonlinear input-aggregator function (e.g., Constant Elasticity of Substitution) is used to derive an expression for input-mix efficiency. Bayesian stochastic frontier is estimated for obtaining mix efficiency using US state-level agricultural data for the period 1960–2004. Significant variation in input-mix efficiency is noted across the states and regions, attributable to diverse topographic and geographic conditions. Furthermore, comparisons of allocative and mix efficiencies provide insightful policy implications. The production incentives such as taxes and subsidies could help farmers in adjusting their input mix in response to changes in input prices, which can affect the US agricultural productivity significantly. The proposed methodology can be extended by i) using flexible functional forms; ii) introducing various time- and region-varying input aggregators; and iii) defining more sophisticated weights for input aggregators.
