将三阶段DEA与Malmquist指数相结合,利用2007—2010年中国31个省级区域的面板数据,对全国、各省级区域、三大地区旅游业的TFP及其分解指数进行了测算与分析。研究结果表明:在剔除了环境变量和随机误差的影响后,中国旅游业的TFP及其分解效率发生了明显变化;居民收入水平、交通便利程度、居民出游偏好和地理区位因素都对中国旅游业的发展效率产生显著影响;在剔除环境变量和随机误差的影响后,2007—2010年期间中国旅游业的TFP呈逐步提升趋势,技术进步是推动旅游业TFP增长的主要动力,技术效率则起抑制作用——这主要源于规模效率水平的下降。  相似文献

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one output – GDP per worker – and three inputs – human capital, public physical capital per worker and private physical capital per worker. We use a semi-parametric analysis, computing Malmquist productivity indexes, and we also resort to stochastic frontier analysis. Results show that private capital is important for growth, although public and human capital also contribute positively. A governance indicator, a nondiscretionary input, explains inefficiency. Better governance helps countries to achieve a better performance. Nonparametric and parametric results coincide rather closely on the movements of the countries vis-à-vis the possibility frontier and on their relative distances to the frontier.  相似文献

Research on tipping has been limited to restaurants, tourism and taxis. This study investigates the economic and demographic factors that influence whether a person tips and the amount tipped for a haircut in a beauty salon. Using a two-step model, it is found that both economic and demographic factors influence tipping behaviour. A person is more likely to tip if he/she has long hair, attends to grooming on a frequent basis, has a lower income, and is male. Price, gender, age, and the use of appointments are factors that influence the amount that one tips.  相似文献

Environmental and economic efficiency has being receiving growing attention among researchers. In general terms, this concept is related to the capability of the economic systems to employ natural resources efficiently, so as to increase economic and human wealth. This clearly implies that both the economic and ecological aspects of decisions ought to be considered. Bearing this in mind, this article considers economic and ecological performance together, by applying data envelopment analysis and the Malmquist productivity index to investigate the efficiency of the 20 Italian regions from 2004 to 2011. The results reveal that the northern regions have been more efficient than the southern ones, highlighting the strong geographical differences between the two. Furthermore, this article uses the grey system theory to forecast regional, economic and environmental efficiency. The results of the forecasting analysis show that the north–south duality remains strong and will possibly increase since the regions in the south get worse in term of environmental and economic efficiency.  相似文献

For some time, two major kinds of Total Factor Productivity (TFP) have existed independently of each other: the Solow residual and the Malmquist Productivity Index (MPI). The Solow residual was introduced in macro economic growth models, and the MPI has been used in micro economics and management studies. As both indices were developed independently, few studies utilize both together and compare the results. This paper uses the same data to compare the two productivity indices by setting to determine the economic implications of combining the two indices. We discovered that we could decompose TFP with each aspect of the Soiow residual and MPI. We could then interpret their relationship in the business cycle. Our results indicated that the frontier shift in MPI of Japanese firms often occurred when the Solow residual increased, meaning that improving oroductivitv with the Solow residual could be generated by a firm that could shift new production frontiers.  相似文献

In Poland, larger farms are often actively promoted over small farms. This policy is based on the perception that there are economies of scale that favor large farms; however, this is contrary to international evidence, which generally indicates that larger farms are less efficient and use less labor than smallscale family farms.

Using both total factor productivity measures and data envelopment analysis, empirical findings from Poland suggest that larger farms are no more efficient than smaller farms, and smaller farms are relatively more labor-intensive. These results have important policy implications for farm restructuring in Poland and other transition economies.  相似文献

中国钢铁行业全要素生产效率实证分析   总被引:2,自引:0,他引:2  
基于动态DEA的非参数Malmquist指数法,分析了1992~2007年中国28个省市钢铁行业全要素生产率以及七大经济区钢铁行业全要素生产率变动情况,并将全要素生产率的变动分解为技术进步、纯技术效率、规模效率三个指标,分析了这三个指标对中国钢铁行业全要素生产率的影响。结果显示,中国钢铁行业TFP的增长主要是由技术进步推动的,当技术进步促进TFP提升时,总会受到技术效率相对下降对TFP增长的抑制;七大经济区钢铁行业全要素生产率存在明显级差,低效经济区学习和追赶高效经济区的效应也应该发挥更大作用;钢铁产业各经济区产能应实现在高效率地区的相对集中,获取行业的规模经济;各经济区都应该注重钢铁行业管理水平的提高,突破钢铁行业能效提高的技术效率瓶颈。  相似文献

This study uses data envelopment analysis to examine the liquidity and sales efficiency of the Food and Beverage listed firms in Athens Exchange in the period 2006–2012. The liquidity efficiency of the firms is higher than the sales efficiency but the results indicate that there are not statistical significant differences in the rankings estimated by the two models in each period. The Malmquist Productivity Index reveals that over the period of the study, firms have experienced an annual average increase in productivity of 0.5% (a slight progress). On examining the components of this productivity change, it becomes evident that firms have experienced an annual average of 2% increase in technology combined with a decrease in technical efficiency of –1.5%. The results indicate that 52.4% of the firms experienced productivity gains in the examined period, and this was mainly the result of technological gain rather than efficiency improvement. More than 90% of the firms in the sample shift the efficiency frontier and only 33.3% of the firms are catching up, improving their productivity by reducing inefficiency. Moreover, the empirical study reveals that the overall technical inefficiencies of the firms are primarily caused by pure technical inefficiencies rather than scale inefficiencies.  相似文献

中国保险业全要素生产率研究   总被引:3,自引:0,他引:3  
基于非参数的Malmquist指数方法,本文对我国1999~2006年间保险业的全要素生产率变化状况进行了动态分析,针对众多的研究方法都存在决策单元规模报酬不变假定,以及决策单元向生产前沿面逼近路径只能选择径向,即仅考虑投入或产出变化情况的缺陷,本文提出修正的Malmquist指数模型.实证发现,中国保险业全要素生产率在1999~2006年问有所提高,其中"追赶效应"较为明显而"增长效应"还未完全显现,这说明保险机构更加注重提高自身技术效率水平而非创新能力提高生产的有效性,依然没有处理好效率进步与技术进步的关系,保险机构需要进一步提升技术创新的能力.  相似文献

The usual measure for the factor land is the total area. But total area is a flawed measure because land is of unequal quality. To account for land quality, we use an alternative measure called effective area. Effective area is based on spatial population distribution which captures both natural conditions and human activity. Theoretically, effective area explains economic growth better than total area that biases the measure of total factor productivity (TFP) growth. Empirically on the basis of 40 years of panel data for the United States, an increase of 10% in effective area is associated with an economic growth of 5%, and the omission of effective area undervalues the growth of TFP by 8.1%.  相似文献

Under situations of limited resources, soft powers such as technology development and innovation become critical capabilities for a nation’s continuous growth and sustainability. Therefore, we used analytical hierarchy process (AHP), data envelopment analysis (DEA), and Malmquist productivity index (MPI) to evaluate the performance of research projects in 6 main fields of study managed by the Ministry of Science and Technology (MOST) in Taiwan from 2002 to 2012. Among the 6 fields of study, Agriculture and Humanities were two research fields as efficiency; and the sequence of inefficiency 4 fields were sociology, medicine, science, and engineering. Although the field of sociology was inefficiency, it was the only field show continuous growth in result of MPI analysis. Taking the fields as a whole, the result of the analysis of total factor productivity showed recession. However, as seen from the growth in technical change and in scale efficiency change, the MOST was effective to a certain extent during the period. However, the recession in technical efficiency change showed that further improvement in the planning and distribution of manpower and funds is needed.  相似文献
