This study estimates and analyzes provincial productivity growth in China for the period 1979–2001. The Malmquist Index approach allows us to decompose productivity growth into two components, technological progress and efficiency change. Considerable productivity growth was found for most of the data period, but it was accomplished mainly through technological progress rather than efficiency improvement. Although China's capital stock has accumulated at record speed in recent years, our findings show that TFP growth slowed down significantly during 1995–2001. The study thus raises serious questions about whether China's recent growth pattern is consistent with its comparative advantages, and whether its reliance on capital accumulation can be sustained in the long run.  相似文献

This study applies a data envelopment analysis (DEA) approach to analyze total factor productivity, technology, and efficiency changes in Chinese agricultural production from 1984 to 1993. Twenty-nine provinces in China were classified into advanced-technology and low-technology categories. The Malmquist (1953) productivity measures were decomposed into two components: technical change index and efficiency change index. The results show that total factor productivity has risen in most provinces for both technology categories during the 1984–1993 period. Technical progress was mostly attributed to Chinese agricultural productivity growth after the rural economic reforms. The deterioration in technical efficiency in many provinces indicates China has great potential to increase productivity through improved technical efficiency. Enhancing rural education and research and development (R&D) in agriculture may also help farmers to improve technical efficiency and productivity in agricultural production.  相似文献

Abstract: The paper examines the economic performance of a large number of African countries using an international comparable data set and the latest technique for analysis. The paper focuses on growth in total factor productivity and its decomposition into technical change and efficiency change components. The analysis is undertaken using the data envelopment analysis (DEA). The present study uses data of 16 countries over the period 1970–2001. It was found that, globally, during that period, total factor productivity has experienced a positive evolution in sampled countries. This good performance of the agricultural sector was due to good progress in technical efficiency rather than technical progress. The region suffered a regression in productivity in the 1970s, and made some progress during the 1980s and 1990s. The study also highlights the fact that technical change has been the main constraint of achievement of high levels of total factor productivity during the reference period in sub‐Saharan Africa. Contrariwise, in Maghreb countries, technological change has been the main driving force of productivity growth. Finally, the results indicate that institutional factors as well as agro‐ecological factors are important determinants of agricultural productivity growth.  相似文献

During China's rural reforms, policies were frequently adjusted. Most policies favoured the continuation and deepening of reform; but some were contradictory or even led to regression in the reform process. How have the rural reforms affected China's agricultural production over the past three decades; and what lessons can be learned to aid the future course of reform? To answer these questions, this study estimates productivity change in China's agriculture and evaluates the effects of policy on agricultural output during the reform period. Aggregated provincial‐level data for the 1979–2008 period are used in a translog production frontier model to estimate indices of total factor productivity (TFP) change and its three components—technical change, technical efficiency change, and a scale effect—with a focus on explaining the variation in technical efficiency. The estimation results show that the impressive improvement of TFP change is dominated by the technical change component. However, technical efficiency change and scale effects have worked against the improvement in TFP change in most periods. To improve technical efficiency, social welfare policies designed to eliminate the rural–urban divide, and reform polices focusing on factor market reforms, such as reform of the household registration system (hukou) and reform of land rights, seem to hold some potential.  相似文献

基于中国29个省区市2014-2018年高技术产业的面板数据,首先采用超效率DEA模型对各省市生产效率进行测算,进而构建DEA-Malmquist模型对各省市综合生产率指数进行计算和分解.结果表明:中国高技术产业创新效率的总体水平较高,但是超过一半的省市区要素投入结构不合理,而且主要分布在中部和西部地区,创新效率存在较大的区域差异;中国高技术产业的全要素生产率指数平均值大于1,很多省份存在规模效率不高的问题,导致创新效率呈现N型的回调震动形态,技术进步和技术效率是全要素生产率提高的主要动力.因此,为了进一步提高我国高技术产业创新效率,需要注意保持高技术产业的技术水平和技术效率,尤其要注重高技术产业科技资源的优化配置,提升高技术产业创新资源的管理水平.  相似文献

One of the most undesirable output of China's rapid economic growth has been increasing carbon emissions. This study measures and analyzes the impact of carbon emissions on China's regional total factor productivity from 2000 to 2017. Using global Malmquist-Luenberger productivity indexes, we re-estimate the provincial total factor productivity taking carbon emission into account, comparing different assumptions of returns to scale and considering the rank reverse issue. The differences of technical progress and efficiency change across Chinese regional economies are also investigated and we found that the former was the primary contributor to improved Chinese provincial productivity performance. In addition, we analyze the influencing factors of productivity based on provincial panel data. Our results indicate that innovation capacity, energy and employment structure had significant impact on the provincial productivities while urbanization had a negative impact. A more sustainable development can be expected by expanding regional investment in R&D, adjusting and optimizing structures of regional industries and energies.  相似文献

This paper reviews the key theories relating to the role of education in economic development and social change and how education, as a critical component of total factor productivity, contributes to sustained economic growth. It examines how China "s education policy reflects the country's unique dual economy. Focusing on the post-reform period, the paper contends that while progress has been made, there are risks to China's future growth prospects from failing to reap the benefits of sound education policy. It argues that if the Chinese education system is to continue to be a driver of rather than a drain on economic growth, and if China is to successfully manage its transition towards more inclusive, sustainable and equitable growth, reforms will be needed to improve the quality of education at all levels and to create an environment in which China's extensive human capital is duly recognized and respected. Crucially, the education system should be transformed to ensure it promotes a comprehensive range of human capabilities, including those that go beyond the part humans play in augmenting production possibilities.  相似文献

Chinese and Indian aggregate productivity growth has been significantly different over the last 30 years. This paper studies the role of structural transformation in accounting for the aggregate productivity growth gap between two economies. We calibrate a neoclassical model of structural transformation for China and India. The model implies that higher productivity growth in China's manufacturing and agriculture accounts for most of the aggregate productivity growth gap between the two countries. According to the development strategy of China's government, China would start a new phase of structural transformation whereby employment is moving from manufacturing to services. Since the productivity growth gap in services is pretty small between China and India, if China wants to remain superior in relative productivity, it should improve the productivity growth rate of services. In contrast, the relative performance in India hinges on closing its productivity gap in agriculture and manufacturing relative to China.  相似文献

To decompose total factor productivity growth into technical progress, technical efficiency change, allocative efficiency change, and scale efficiency change, a stochastic frontier approach was applied to Malaysian manufacturing data covering the period 2000 to 2004. The results show that total factor productivity was driven mainly by technical progress but was hurt by deteriorating technical efficiency. Scale efficiency and allocative efficiency also exerted significant influences on total factor productivity. The skill and quality of workers were the most important determinants of technical efficiency, whereas foreign ownership, imports, and employee quality underpinned technical progress. The impact of firm size on scale economies differed across industries.  相似文献

为了分析电网行业的生产率受技术进步和技术效率的影响程度,使用基于DEA的Malmquist生产率指数方法,以9家省电力公司为样本,对电网企业的技术和生产效率的动态变动情况进行了研究。结果表明,2005-2010年间样本电网企业的全要素生产率年平均增长率为3.2%,技术进步的贡献大于技术效率的贡献。技术效率指数表现不优是由于多数样本企业的实际规模与最佳规模之间的偏差较大。因此为了提高我国电网企业生产率,关键是提升效率特别是规模效率。  相似文献

In the present study, we develop a stochastic frontier production model that allows for different groups of firms to have different patterns of technical efficiency over time. We apply our model to the Malaysian manufacturing sector to decompose total factor productivity growth into technical efficiency change and technical progress for different plant size groups (e.g. large and small) in seven industries during 2000–2004. Our empirical results indicate that technical efficiency has worsened across all industries and plant‐size groups. In contrast, we find evidence of substantial technical progress in all industries. In fact, technical progress has been larger than technical efficiency deterioration in most industries and plant‐size groups, leading to total factor productivity growth. Our analysis identifies the industries and plant‐size groups that lag the most in terms of productivity, and thus have the greatest scope for policies that facilitate productivity growth.  相似文献

This paper uses a varying coefficients frontier production function model to examine the sources of growth between 1987 and 1993 in four East Asian economies—Hong Kong, Singapore, Japan and South Korea. Using data for 20 manufacturing sectors at the three-digit SIC level, this study provides the first comprehensive examination of sources of growth that allows one to decompose total factor productivity growth, separating out technical efficiency changes (TECs) from technological progress (TP). We find that while there is ample evidence of the importance of increasing inputs in growth, and there is some support for technical efficiency change, or catching up to the frontier over this period, there is weak or even negative evidence for the role of technological progress, measured as a shift in the estimated production frontier.  相似文献

本文采用超越对数的随机前沿生产函数和1998-2009年的省际面板数据,测算了中国各地区装备制造业的全要素生产率(TFP)增长率,并从技术进步、技术效率变化、规模效率变化、配置效率变化四个方面对中国装备制造业全要素生产率变化的特点进行了分析。经验结果表明,样本期间内,全国以及东、中、西部地区装备制造业的TFP都有所增长,其增速皆呈现出先增后减再增的趋势;TFP增长对全国装备制造业产出增长的贡献率相对较低,仅为0.117。对TFP增长的分解发现,技术进步已成为中国装备制造业TFP增长的主要源泉,配置效率和规模效率恶化则严重阻碍了中国装备制造业TFP水平的提高。分地区来看,中部地区的TFP增长率最高,东部次之,西部最低,这主要是由于西部地区装备制造业要素配置效率的下降最为严重,东部地区规模效率的下降最为严重。  相似文献

在传统Solow增长核算框架基础上引入异质性劳动投入以及技能偏向性技术进步,从而将经济增长分解为固定资本投入增长、劳动投入增长、技能结构深化、技能偏向性技术进步、中性技术进步及效率改进等五种动能。研究发现:第一,中国经济增长主要由固定资本投入以及全要素生产率增长共同驱动,其中资本投入对经济增长年均贡献率为61.64%,全要素生产率增长的年均贡献率则为35.66%,中国区别于其他中低收入国家的发展奇迹背后正是较快的全要素生产率增长;第二,即使对于高收入国家而言,资本投入仍然是主要的经济增长动能;第三,技能结构深化以及技能偏向性技术进步是全要素生产率的主要来源,二者对中国经济增长的年均贡献率分别为32.04%和21.27%;第四,资源配置效率变化是引起全要素生产率波动的主要因素,资源配置效率下降是导致2008年后中国以及大部分高收入国家全要素生产率增速放缓的主要原因。  相似文献

We study the impact of a national energy efficiency program on total factor productivity (TFP) growth in firms in China's iron and steel industry. Using detailed firm-level survey data and multiple approaches to estimate program effects, we find participating firms experienced greater annualized TFP change. Our base specification estimates the program increased annual TFP growth by 3.1 percentage points, implying an annual private benefit of 148.7 million RMB/year per firm, with approximately equal contributions from technical change and scale efficiency change. Our results suggest that firms undervalued energy efficiency investments prior to the start of the program.  相似文献

This paper provides a comprehensive analysis of the productivity effects of antidumping (AD) measures on Chinese industries. Industry‐year panel data and generalized method of moments estimators are used in the empirical analysis. Productivity indicators are calculated using data envelope analysis. The empirical results show that China's industrial total factor productivity has improved under the pressure of AD measures taken by developed countries, and the mechanism inspires technological progress but hurts technological efficiency. Developing countries' AD measures have no significant productivity effects on China's targeted industries, except for slightly positive effects on technological efficiency. These results indicate that China should pay more attention to technological innovation and take different counter‐measures for different cases of AD measures.  相似文献

This paper studies the interaction between foreign trade and domestic demand and supply in China's economic transformation. It compares China's export dependency with other economies using input–output analysis. The paper also conducts econometric analysis of provincial level data to examine causality between the growth of foreign trade and components of domestic demand, and causality between the growth of foreign trade and total factor productivity. The main message is that China's export dependency is significantly lower than implied by the headline exports-to-GDP ratio. Moreover, the contribution of export to economic growth in China came mainly from its impact on total factor productivity growth from a supply perspective rather than its multiplier effect from a demand perspective. This relationship was found to be stronger in the more developed coastal areas than in the less developed inland areas.  相似文献
