我国技术效率、技术进步与生产率区域差异的实证研究

本文用非参数Malmquist指数方法研究了我国全要素生产率的增长状况及其区域差异,并将其分解为技术进步和技术效率,同时采用增长回归法对我国地区之间TFP、技术效率、科技进步的差异进行了检验。研究表明:1994-2007年间我国全要素生产率年均增长率达到1%,主要得益于技术进步水平的提高,技术效率总体上呈现下滑趋势;我国各省市区的科技进步、技术效率、TFP变化呈现出较为明显的差异,其中TFP和科技进步变化差异最为明显,而技术效率变化差异不大。     

Parametric Decomposition of a Generalized Malmquist Productivity Index

This paper provides a parametric decomposition of a generalized Malmquist productivity index which takes into account scale economies. Unlike Balk (2001), the contribution of scale economies to productivity change is evaluated without recourse to scale efficiency measures, which are neither bounded for globally increasing, decreasing, or constant returns to scale technologies nor for ray-homogeneous technologies. An empirical application using panel data from Spanish savings banks is included. This application shows the advantages of the suggested method compared to Balk's approach. The results show an increase of total factor productivity which can be mainly attributed to technical progress and the positive effect of returns to scale.     

Some Remarks on Productivity and its Decompositions

This paper provides a brief history of the Malmquist productivity index and its decomposition. Theoretical and empirical issues related to the index are discussed along with directions for future research.     

Productivity and efficiency in the US: effects of business cycles and public capital

We add to the literature on the US productivity slowdown and effects of public capital on productivity by employing Malmquist productivity indexes to measure productivity. These indexes allow us to decompose productivity growth into efficiency change and technological innovation. We derive these components for each observation, which we exploit to explore factors which may lead to differences in productivity across regions, including business cycles, both own-state and cross-border public infrastructure investment, and relative sizes of the manufacturing, service and public sector. Our results suggest that the components of total factor productivity change lend important insights into the fairly complex effects of public capital on productivity growth.     

Productivity change in Brazilian water services: A benchmarking study of national and regional trends

Assessing the evolution of the performance of water supply and sanitation services is essential to monitor progress towards the universalization of water services, as specified by the Sustainable Development Goal 6 of Agenda 2030, adopted by United Nations member countries. Brazil, a developing country with a continental size and geographical diversity, will face significant challenges to achieve this goal. The main objective of this paper is to evaluate the evolution of productivity of water supply and sanitation services in Brazilian municipalities in the period 2012–2019. The analysis also explores whether water services’ performance is balanced across the country, with a specific analysis of performance at the macroregion level. From a methodological perspective, this research evaluates productivity change over time using a Malmquist Productivity Index estimated with a metafrontier, satisfying the circularity property. It also develops a pseudo Malmquist index that compares productivity levels across macro-regions. The results revealed a productivity loss of approximately 4% at the national level, with an unequal profile across the macro-regions. The Southeast municipalities stand out for exhibiting, on average, higher productivity levels than the South and Northeast municipalities.     

中国保险业全要素生产率增长分解与分析

研究1999年至2003年我国保险业全要素生产率增长趋势,并将其分解为前沿技术进步、纯技术效率的变化、规模效率的变化三大因素。研究发现,保险业的全要素增长率呈现逐年上升的趋势;前沿技术进步已成为我国保险业全要素生产率增长的最主要动力;保险公司相对前沿的技术效率差距拉大,已出现阻碍全要素生产率增长的趋势,但这种技术效率的差距不是因纯技术效率的差异影响而是受规模效率的影响。     

The Decomposition of Malmquist Productivity Indexes

Two different Malmquist productivity indexes have been proposed. One I call partially oriented because it is either output- or input-oriented, and the other is simultaneously output- and input-oriented. The partially oriented Malmquist index owes some of its popularity to the fact that it has been decomposed to isolate various sources of productivity change. Conversely, the simultaneously oriented Malmquist index has not achieved popularity in part because it has not been decomposed. In this paper I evaluate alternative decompositions of the partially oriented Malmquist index, and I obtain a new decomposition of the simultaneously oriented Malmquist index. This new decomposition leads me to conclude that the latter index is deserving of greater attention than it has received to date.     

生产性服务业生产率与经济增长关系分析

生产性服务业作为现代服务业的核心,集中体现了对经济的促进作用。生产性服务业通过提高经济增长效率、延展产业链和促进就业,推动了经济的增长,而经济的增长也为生产性服务业的发展提供了所需的基础设施和经济环境。     

Productivity Growth in the Western Hemisphere (1978–94): The Caribbean in Perspective

Productivity growth, technical efficiency change, and technological change were measured for a sample of 30 countries in the Western Hemisphere for the 1978–1994 period using the Malmquist index. The Caribbean compared unfavorably with North America and the Latin American regions. Evidence indicated some support for the convergence hypothesis. Regression analysis indicated that productivity growth in the Caribbean was positively associated with civil, economic, and political liberty.     

我国城市经济增长效率与城市化效率比较分析

利用数据包络分析的曼奎斯特指数方法测算了2000-2008年我国248个城市的经济增长效率和城市化效率,比较分析了不同区域、不同等级城市的效率表现。研究发现,我国城市经济增长效率持续提高,但城市化长期处于低效率状态,严重滞后于经济增长;地级市两种效率的初始领先地位已逐渐被直辖市所取代;东部地区城市的效率表现优于其他地区,但不同等级城市之间差异较大,城市化严重滞后和轻微滞后的城市数量都比较多。认为通过合理的空间规划和产业引导,提高城市化效率、促进城市化与国民经济增长协调发展,是下一阶段城市发展要解决的关键问题。     

中国文化上市企业全要素生产率研究

本文利用2008~2012年中国文化上市企业的相关财务指标数据,应用DEA-Malmquist指数方法对19家文化企业的全要素生产率(TFP)增长进行了测算和分解分析。研究结果为:首先从平均水平来看,TFP有着微弱的增长(0.7%),但主要是依靠规模扩张的粗放型方式来实现,而并非通过集约型的生产率提升来实现;其次部分企业的TFP呈现出明显的递减趋势,并且主要由技术进步的负增长贡献;最后,本文提出了相应的政策建议。

Measuring destocking performance of the Chinese real estate industry: A DEA-Malmquist approach

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.

Sequential Malmquist Indices of Productivity Growth: An Application to OECD Industrial Activities

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.
