我国中小企业融资约束、代理成本与生产效率关系研究——基于我国180家上市公司的统计数据

中小企业是我国国民经济发展的重要组成部分,对于我国国民经济持续稳定的发展有着重要的促进作用。但是我国中小企业由于存在规模都比较小、体制不完善等问题,因此在融资时有许多困难;并且现代企业制度所有权和经营权分离,又会出现代理成本问题;同时目前国内生产资料价格普遍上升,就如何提高生产效率降低生产成本成为这些中小企业共同面临的问题。文章就上述中小企业问题进行实证研究,检验了融资约束、代理成本与生产效率之间存在的关系。     

儒家始祖形象的三种形态及其意义

传统儒家从未停止对事物根源与本质的探索。所谓物有本末,事有终始,始之字义常常兼具逻辑上的原初性与价值上的根本性。始祖作为生民存续之始和人道的开端,其形象隐含着重要的理论意义,更关联着儒家思想与制度的核心。本文分别从感生之祖、始封之祖、生民之祖三种形态出发,追溯始祖形象的特点,并试图通过这一讨论来理解儒家家国建构的不同模式及其基础。     

Railway development from the Japanese occupation period to the present – using Kaohsiung city as an example​​​​​​​​

This study intended to discuss the interactive influence of the emergence, transformation and decline of the railway in Kaohsiung Port on urban development, the population, the activities and the economy in the region during the period of 1895–2010, from the perspectives of urban planning, railway development, population and industry. This study used the crossover analysis method, and used the factors of railway development and urban planning, within a fixed time period, to explore the chain dependence relationship among the industry, the population, the regional economy and the railway stations in Kaohsiung city. This study found that urban planning, economic development, railway development and industry have an interactive influence on the overall urban development. Urban planning promotes the rapid growth of the population, and economic development propels the growth and shaping of the regional economy, thus increasing employment opportunities. In addition, the railway development process moves forward with urban development.     

Technology elasticity and potential on energy saving and emission reduction: evidence from China

This article investigates the elasticity of different technology choices to energy efficiency and chemical oxygen demand/ammonia nitrogen emission reducing efficiency among 38 industries in China from 2008 to 2011. With data envelopment analysis, total-factor productivity growth, the common measure of technical progress, is divided into different parts: technical efficiency relative to the frontier, technology change and scale efficiency, which are regarded as three different choices of technological progress. For various industries, technology elasticity is quite different and the importance of different technical choices is diverse in the improvement of efficiency on energy saving and emission reduction. Policymakers could focus on the elasticity of different technical progress choices in various industries to improve energy and emission reduction efficiency.     

The relationship between population growth and standard-of-living growth over 1870–2013: evidence from a bootstrapped panel Granger causality test

This paper examines the linkages between population growth and standard-of-living growth in 21 countries over the period of 1870–2013. We apply the bootstrap panel causality test proposed by Kónya (Econ Model 23:978–992, 2006), which accounts for both dependency and heterogeneity across countries. We find one-way Granger causality running from population growth to standard-of-living growth for Finland, France, Portugal, and Sweden, one-way Granger causality running from standard-of-living growth to population growth for Canada, Germany, Japan, Norway and Switzerland, two-way causality for Austria and Italy, and no causal relationship for Belgium, Brazil, Denmark, Netherlands, New Zealand, Spain, Sri Lanka, the UK, the USA, and Uruguay. Dividing the sample into two subsamples due to a structural break yields different results over the two periods of 1871–1951 and 1952–2013. Our empirical results suggest important policy implications for these 21 countries as the directions of causality differ across countries and time period.     

On Minimally-supported <Emphasis Type="Italic">D</Emphasis>-optimal Designs for Polynomial Regression with Log-concave Weight Function

This paper studies minimally-supported D-optimal designs for polynomial regression model with logarithmically concave (log-concave) weight functions. Many commonly used weight functions in the design literature are log-concave. For example, and exp(−x ²) in Theorem 2.3.2 of Fedorov (Theory of optimal experiments, 1972) are all log-concave. We show that the determinant of information matrix of minimally-supported design is a log-concave function of ordered support points and the D-optimal design is unique. Therefore, the numerically D-optimal designs can be constructed efficiently by cyclic exchange algorithm.     

Worker Productivity, Working Time Reduction, And The Short–Run And Long–Run Employment Effects

This paper illustrates a shirking–type efficiency wage model to explain why shorter working hours cause an ambiguous effect on employment as the empirical result. We find that shorter working hours have an uncertain impact on the work effort, and the relationship between work effort and shorter working time is a decisive factor in the employment effect of working time reduction. Moreover, it is also found that, given the zero profit constraint, the long–run employment effect of reducing working hours will intensify the short–run employment effect.     

Assessing market power in the U.S. commercial banking industry under deregulation

This study attempts to investigate market power in the U.S. commercial banking industry since the U.S. government began to deregulate the banking sector in the early 1990s using the static Bresnahan–Lau model (SBLM) and dynamic Bresnahan–Lau model with error corrections (DBLEC). In particular, panel unit root and panel cointegration techniques are utilized to examine the dynamic model. The empirical results of the SBLM show that the banking industry is highly competitive. The empirical results of DBLEC also suggest that the commercial banking industry is close to being perfectly competitive in the short run. By contrast, the adjustment speeds of the supply and demand sides towards the long-run equilibrium are quite slow in that market, which implies that the U.S. commercial banks enjoy a certain degree of long-run market power.     

Using a balanced scorecard to improve the performance of an emergency department

The performance of the emergency department significantly improved after implementing the balanced scorecard including hours of continuing education attended by the staff, staff job satisfaction, the rate of incomplete laboratory tests within 30 minutes, the average monthly inappropriate return rate, and hospital profit. The results can assist administrators plan for the future. Although this was a pilot program for implementing a balanced scorecard in an emergency department, the indicators used in this study may also be reasonable for a hospital that has limited resources.
