Determinants of Technical Efficiency in Chinese Banking: A Double Bootstrap Data Envelopment Analysis Approach

Abstract

The main objective of this study is to measure the technical efficiency level of the Chinese banking industry. It uses a double bootstrap data envelopment analysis approach to compute bias-corrected efficiency scores and investigate the determinants of bank efficiency in China between 2003 and 2010. We observe that Chinese commercial banks regardless of ownership have shown improved efficiency from 2003 to 2010. Our results show a significant difference in the performance between state-owned banks and joint-stock banks over the period analyzed. Moreover, the equity-to-asset ratio also significantly explains variations in inefficiency across Chinese commercial banks. Initial public offering is considered one of the effective ways to improve bank efficiency in China. Overall, the present study provides valuable empirical information that can be used to help guide deliberations regarding future reform policies.

粤港澳大湾区背景下江门物流产业效率及其提升策略研究

本文运用DEA效率测度模型,对江门市物流产业效率进行了测算,并与珠三角各城市进行了对比差异分析,结果显示:在2013-2018年期间,江门物流产业技术效率处于低水平稳定状态,技术效率平均值仅为0.53,在珠三角九市中排名第七位。纯技术效率下降是制约江门物流产业技术效率提升的主要因素,规模效率处于上升趋势,且每年规模效益处于递增状态。     

Firm Efficiency in a Transitional Economy: Evidence from Vietnam

The paper examines efficiency performance of the non-state small and medium manufacturing industries in a transitional and developing economy. Using firm level data in Vietnam from 1996 and 2001, cross-sectional models are estimated using the stochastic frontier method. The results show a considerable variation in efficiency levels among firms and that a greater use of family labor and a metropolitan location are associated with improvement in technical efficiency. The results indicate few benefits from direct government financial and non-financial assistance to businesses.     

电价交叉补贴阻碍绿色发展效率吗——来自中国工业的经验证据

文章以2007-2013年中国30个省、自治区和直辖市为样本,用NDDF-DEA方法评估了各地区工业绿色发展效率,运用CLAD估计方法实证分析了电价交叉补贴对工业绿色发展效率的作用机制。结果表明,从全国层面来看,电价交叉补贴通过要素投入和成本机制对中国工业绿色发展效率产生消极影响;从分地区层面来看,虽然电价交叉补贴对各地区工业绿色发展效率的影响途径一致体现于要素投入和成本机制,但其影响程度存在较大的空间差异,电价交叉补贴会显著阻碍东部地区工业绿色发展效率提高,而对中西部地区工业绿色发展效率没有显著消极影响,甚至有利于工业绿色发展效率提高。     

基于DEA模型的我国物流业效率评价研究

有效评价城市物流效率是科学配置和规划城市物流资源的基础。选取2004-2013年我国物流总产值作为研究样本,以等级公路里程、固定资产投资和物流从业人数作为输入指标,以货运量、货物周转量作为输出指标,构建我国物流业的效率评价模型,对综合技术效率、纯技术效率、规模效率三个方面进行综合评价。结果发现：近年来,公司的整体效率虽然有所提高,但仍然偏低,物流业的经营管理效率有待提高。最后给出相关的政策建议。     

A New Approach to Measuring a Multidimensional Productivity Index: An Application for 60 Selected Countries

This study aims to develop a productivity index which takes into account the multidimensional characteristics of productivities. Our multidimensional productivity index (MPI) not only measures individual productivities of economic resources but also evaluate productivity enhancing general capacities of economy. Individual productivity indices such as labor productivity are limited because they do not consider the factors, such as the globalization of economies and the market and institutional variables, that could have profound impacts on productivity. The multidimensional Productivity Index (MPI) is measured for 60 countries including 23 OECD countries and 10 Asian countries. Our methodology employs the concept of technical efficiency that allows us to measure the extent to which institutional and market factors contribute to the economic performance. Our findings indicate that standard productivity measures such as labor productivity may overestimate the overall productivity differences across the economies.

Technical Efficiency of Rice Farms in Different Agroclimatic Zones in the Philippines: An Application of a Stochastic Metafrontier Model*

Rice producers in the Philippines operate in spatially diverse physical environments that are largely beyond their control. We decompose total factor productivity into technical efficiencies and environment–technology gap ratios across four climatic zones for selected years from 1996/1997 to 2005/2006 using farm‐level panel data. Results show surprisingly little interzonal and intertemporal variation in productivity. It appears that Philippine rice producers have been able to adapt their crop management strategies sufficiently to suit their particular agroclimatic conditions. However, after an increase in the first 5 years of the study period, mean environment–metatechnology gap ratios stagnated in the second 5 years. The metafrontier does not appear to have substantially shifted outwards over the whole period, suggesting that rice producers achieved little technological progress and increased total factor productivity.

The health costs of the industrial leap forward in China: Evidence from the sulfur dioxide emissions of coal-fired power stations

In this study, we attempt to empirically test the effects of air pollution on public health in China. Using three-stage least squares (3SLS) to solve the potential endogeneity problem in sulfur dioxide (SO₂) emissions, we find that air pollution has significant negative effects on public health. Specifically, a 1% increase in SO₂ emissions is found to lead to 0.067 and 0.004 more deaths per 100,000 population due to respiratory diseases and lung cancer, respectively. In terms of absolute magnitude, every one million ton increase in SO₂ emissions results in 0.735 and 0.052 extra deaths due to respiratory diseases and lung cancer per 100,000 population, respectively. Moreover, SO₂ emissions result in 230,000 extra deaths every year and the related economic costs over the study period amount to RMB 8.179 billion.     

服务业全要素生产率测度及其省际差异

运用2005～2009年中国31省份服务业面板数据,采用非参数Malmquist指数方法,对中国服务业全要素生产率的变动原因、空间差异与变动趋势进行考察,并将全要素生产率进一步分解为技术效率和技术进步。研究结果表明,中国服务业整体仍表现为粗放型的增长方式,全要素生产率呈现负增长,但增长速度有所放缓;服务业发展水平的空间差异明显,东部地区服务业发展水平高于中西部地区,其中西部和东北地区服务业发展水平较落后,且技术进步和技术效率对中国及各区域服务业的全要素生产率在时间和空间上有不同的影响。     

The Efficiency of the Chinese Commodity Futures Markets： Development and Empirical Evidence

I. Introduction In the early 1980s China set about transforming its moribund economy by adopting, in stages, various elements of the market-based systems. Among the reforms were thederegulation of prices and the introduction of financial markets for assets. The first stock market was set up in Shanghai in 1991 and in the same year the first commodities market opened in Zhengzhou, Henan Province. Since then, both the stock market and the commodities futures markets have expanded substantiall…

The technological system of Chinese manufacturing industry: A sectorial approach

The purpose of this paper is to analyze the technological system of Chinese manufacturing. The input–output method and network analysis are applied to investigate the structure and performance at the system level and the role of each sector at the individual level in 1997 and 2002. Firstly, the R&D-flow matrices for per unit output are constructed to examine the technology intensity and constitution of each sector. And then they are combined with the economic size and R&D investment structure in order to have a more comprehensive understanding of the system at the gross level, and reveal the main technology diffusion providers, acquirers and techno-economic flows between sectors. Results of both years show that the R&D performance and technology providing for diffusion are more concentrated than technology acquiring, and this difference becomes even greater in 2002. There are fewer sectors which act as main technology diffusion sources while more sectors participate as acquirers of technology diffusion. The techno-economic flows have high dependence on a few traditional sectors and the contribution of high-tech sectors such as ICT is quite limited.
