Sequential Malmquist Indices of Productivity Growth: An Application to OECD Industrial Activities 总被引:2,自引:0,他引:2
The paper applies both the standard DEA methodology with contemporaneous frontiers and DEA with sequential frontiers to study changes in productivity and efficiency in manufacturing for a sample of eleven OECD countries over a twenty-year period. It uses a decomposition of the industrial Malmquist productivity indices to locate the sources of productivity growth: 'technical progress' and 'catching up.' The alternative indices are interrelated in a unifying framework that provides an interpretation to their difference. We argue that for manufacturing industries, in which technological regress is unlikely to occur, DEA with sequential frontiers provides a more adequate measure for the contribution of technical changes than standard DEA. 相似文献

人力资本与区域全要素生产率分析 总被引:81,自引:1,他引:81
本文采用Malmquist指数分析了我国30个省级行政区1996—2003年的全要素生产率(TFP)增长,并将其分解为技术进步指数和效率变化指数。为了减少计算偏差,我们在使用承认无效率项存在的生产前沿技术的同时,引入了人力资本要素。本文的分析结果表明我国的人力资本水平增长迅速,30个省区的经济增长效率差距逐年扩大。同时我们发现在引入人力资本要素后,1996—2003年区域全要素生产率的增长得益于技术进步;如果不考虑人力资本存量,则低估了同期的效率提高程度,而高估了期间的技术进步指数。 相似文献

中国城市经济增长的效率与差异 总被引:13,自引:0,他引:13
李培 《数量经济技术经济研究》2007,24(7):97-106
本文在利用Malmquist指数和一系列反映地区差异的统计指标对中国216个地级市1990~2004年经济增长的效率和差异进行描述的基础上,针对2000年以来中国城市经济表现出的新特点,采用因子分析和空间计量方法分析了影响中国城市经济增长的主要因素,结果表明216个地级市TFP整体呈现增长趋势,城市经济的地区差异明显且呈扩大趋势。2000年以来影响中国城市经济增长的因子强度依次为:地理位置、产业结构与市场化水平和要素投入等。 相似文献

This paper uses the Malmquist index to examine the sources of Total Factor Productivity (TFP) in Chinese agriculture. The
overall goal of this study is to create a framework for assessing the trend of China’s agricultural infrastructure and to
measure its impact on Total Factor Productivity. The main methodological contribution is to provide more contributive measure
of crop-specific technologies. Based on the province-level panel data set during 1988–2002, the primary finding is that infrastructure
has positively and statistically significant association with the estimated coefficient on Total Factor Productivity for rice,
wheat, maize, and bean.

This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.JEL classification: D24, G21This paper was written while Dogan was a member of Monash University Malaysia.

文章利用超效率DEA模型和Malmqulst指数模型分别测算了江苏13市2001-2012年旅游业发展的静态效率与动态效率。结果显示:江苏旅游业静态效率保持先降后升的态势,从2001年的0.848下降到2006年的0.611,后又上升到2012年的0.824,12年间效率均值为0.726。各市旅游业效率存在显著的地区差异,且呈现逐步扩大的趋势。江苏旅游业动态效率(TFP)年均变化值-0.6%,增长主要来源于技术进步而不是规模效率的作用。在以上研究的基础上,提出提升江苏旅游业效率的对策,为旅游业持续、高效、健康发展提供理论参考。 相似文献

This article analyzes the productivity growth of the Spanish dairy processing industry from 1996 till 2011, which concerns the period of increased EU regulation regarding food safety as well as economic crisis. Data envelopment analysis is used to compute the Malmquist index and its components. The results suggest that productivity on average declined during the period under investigation. The decomposition of the Malmquist index finds that technical regress contributed to productivity decline despite improvements in technical and scale efficiencies. Our results also suggest that food safety regulations did not have a negative impact on productivity growth. Technical change and scale efficiency change made significant negative contributions to productivity growth in the period under crisis, whereas firms significantly improved their technical efficiency in that period. 相似文献

Using data envelopment analysis and the Malmquist productivity index, this paper studies productivity efficiency of various airlines in China after the Chinese government deregulated the aviation industry in 2005. The results show that the productivity efficiency of non-state-owned airlines improves rapidly and eventually exceeds state-owned airlines after the deregulation policy. Among the state-owned airlines, the productivity of the local airlines and their technical changes are better than those of the central airlines. 相似文献

[目的]从静态分析和动态分析两个方面,阐释长江经济带农业绿色生产效率和农业绿色全要素生产率的时空分异特征以及生产率增长来源,以期为提高长江经济带农业绿色发展质量提供科学决策依据。[方法]文章基于资源环境约束的角度,利用MinDS模型和Global Malmquist Luenberger指数相结合的方法,测算长江经济带农业绿色生产效率和农业绿色全要素生产率,并将农业全要素生产率变化分解为纯技术效率变化(PEC)、纯技术变化(PTC)、规模效率变化(SEEC)和规模技术变化(SETC)4个部分。[结果](1)长江经济带农业绿色生产效率水平较高,且呈不断增长趋势,下游地区的农业绿色生产效率高于中、上游,且中、上游与下游地区的差距不断拉大; (2)长江经济带农业绿色全要素生产率增长较快,以3年为1个周期,呈现波动式上升趋势,其增长主要源于纯技术进步和规模技术提高; (3)长江经济带下游农业绿色全要素生产率增长率最高,上游次之,中游最低,其中,下游农业绿色全要素生产率增长主要源于纯技术进步,中游是纯技术效率改进、纯技术进步和规模技术提高共同作用的结果,上游则源于纯技术效率改进、纯技术进步和规模效率提高。[结论]长江经济带上、中、下游三大区域的农业绿色发展水平和发展能力存在较大差异,需制定差异化政策,以调整农业增长模式,促进农业转型升级,实现高质量发展。 相似文献

This paper aims to measure the evolution of destocking performance of the Chinese Real Estate Industry based on a DEA (Data Envelopment Analysis)-Malmquist approach, which is seldom used in this industry in existing literature. In 2016, the Chinese government introduced a unified national destocking policy to reduce real estate inventory to save the downturn in the real estate market, but the effect was less than expected and led to soaring house prices in first-tier cities. By analysing the destocking performance over the period from 2005 to 2015, we find the following: (1) It is impossible to use a unified policy to effectively address the national destocking issue because of the difference of DMUs' destocking efficiency, input redundancy and total factor productivity score changes. (2) With the current destocking performance and investment status, the government is still ignoring the existing commercial real estate problems. (3) The redundancy of firm assets and staff indicates that zombie firms may exist and risk future unemployment in the real estate industry. (4) Despite the recently repeated government interventions in this industry, destocking performance remains falling since 2008, and problems in other regions is more severe than in central cities. (5) The financial crisis triggered by the US subprime mortgage crisis has had a great impact on China's real estate industry. The destocking performance dropped sharply in 2008, forcing the Chinese government to introduce policies to stimulate the real estate market. Policy recommendations are also put forward based on the findings. 相似文献
