我国省际边界区域的研究进展及展望

省际边界区域既是省级经济政策的交汇区,又是区域摩擦的集中地,空间协调难度较大,统筹发展难点较多,是和谐社会建设所面临的重大问题之一。我国省际边界区域研究内容主要包括边界区域的理论内涵、影响因素、产业发展、空间组织结构模型、空间管治以及发展战略和对策等。这些研究多以现状的描述为主,并没有形成完整的理论体系。在全球化、网络化和信息化以及科学发展观的背景下,省际边界区域已成为我国区域统筹发展的重点,在今后的研究中要重视探讨以“边界效应”理论为基础的边界区域经济学,深入分析省际边界区域的产业分工与合作,深化研究省际边界区域空间结构演化及优化路径,加快构建省际边界区域协调发展的定量系统模型,科学完善省际边界区域协调发展理论体系。     

Embodied and Disembodied Technical Change in Fisheries: An Analysis of the Sète Trawl Fishery, 1985–1999

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year.     

旅游资源价值评估问题探析

旅游资源价值评估是目前旅游资源学、资源经济学和环境经济学等学科研究的热点和难点。本文在介绍旅游资源价值评估的理论基础上,回顾了旅游资源价值评估的国内外研究进展,详细介绍了TCM和CVM两种经典评估模型,并在此基础上提出了目前旅游资源价值评估存在的三大问题：第一,旅游资源价值构成体系尚未形成统一的认识,本文在参考已有的价值分类系统基础上,提出了旅游资源价值构成体系；第二,现有价值评估方法有待深入研究,本文指出了旅行费用法(TCM)和条件价值法(CVM)两种经典评估模型的不足；第三,旅游资源价值动态变化的影响因子体系尚未明确。     

Coping with Technological Change: The Role of Ability in Making Inequality so Persistent

This study provides an explanation to the evolution of wage inequality over the last 30 years and supports this explanation with evidence. A faster rate of technological progress introduces new unknown elements at the workplace. The need to cope with the unknown accentuates the role of ability and thus increases wage inequality within and between education groups. Inasmuch as education is an irreversible investment project the rise in within group inequality BOOSTS UP the rise of between group inequality. Guided by this theory we turn to the PSID for evidence. Using parents' education to approximate child's ability we show the following set of results: (a) Controlling for education of the child, parents' education contributed much more in the 1980s to his wage growth than in the 1970s. (b) The correlation between the parents' and the child's education increases from the 1970s to the 1980s. (c) The return to college education for an individual with no ability rents did not change—it remains steady at the 23 percent. (d) Facts (a)–(c) CANNOT be attributed to the impact of parent's income. It is parents' education and not parents' income that is more relevant for son's economic outcomes in the 1980s.     

2002～2005年间我国不同地区高校科技创新效率比较研究

利用SPSS13.0对2002～2005年间我国各省、市、自治区高校科技创新活动进行了聚类分析,并采用DEA的CCR模型对这4年中我国各省、市、自治区高校科技创新过程中经费支出,以及人员投入的效率问题进行了比较研究,结果发现有24个地区DEA有效,6个地区非DEA有效。最后给出了非DEA有效地区的改进方向。

A Stochastic Frontier Production Function with Flexible Risk Properties

This paper considers a stochastic frontier production function which has additive, heteroscedastic error structure. The model allows for negative or positive marginal production risks of inputs, as originally proposed by Just and Pope (1978). The technical efficiencies of individual firms in the sample are a function of the levels of the input variables in the stochastic frontier, in addition to the technical inefficiency effects. These are two features of the model which are not exhibited by the commonly used stochastic frontiers with multiplicative error structures.An empirical application is presented using cross-sectional data on Ethiopian peasant farmers. The null hypothesis of no technical inefficiencies of production among these farmers is accepted. Further, the flexible risk models do not fit the data on peasant farmers as well as the traditional stochastic frontier model with multiplicative error structure.     

Productivity Growth, Efficiency and Outsourcing in Manufacturing and Service Industries

This paper is a survey of recent contributions to, and developments of, the relationship between outsourcing, efficiency and productivity growth in manufacturing and services. The objective is to provide a thorough and up–to–date survey that provides a significant discussion on data, as well as on the core methods of measuring efficiency and productivity. First, the readers are introduced to the measurement of partial and total factor productivity growth. Different parametric and non–parametric approaches to the productivity measurement in the context of static, dynamic and firm–specific modelling are discussed. Second, we survey the econometric approach to efficiency analysis. The issues of modelling, distributional assumptions and estimation methods are discussed assuming that cross–sectional or panel data are available. Third, the relationship between outsourcing and productivity growth in manufacturing and services is discussed. The correspondence between a number of hypotheses and empirical findings are examined. Examples of varieties of relevant empirical applications, their findings and implications are presented. Fourth, measurement of inputs and outputs in manufacturing and services are discussed. Finally, to promote useful research, a number of factors important to the analysis of outsourcing, efficiency and productivity growth in the service sector are summarised.
