基于污染损失率的连云港水环境污染功能价值损失研究

水体污染是当前环境污染一个重要方面,有效评价水污染的价值损失是水环境规划、制定水环境对策与政策的基础。文章基于污染损失率法估算连云港水环境的功能价值损失,得出1996—2000年连云港的水环境污染功能价值损失年均高达11.8亿元,占GDP的比重年均为4.55%。表明连云港水环境污染损失较大,其经济发展在一定程度上是以水环境污染为代价的;目前以GDP为主要衡量指标的国民经济核算体系可能过高地估计了连云港的经济增长水平。

The Role of Water in Manufacturing

Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation.     

On the existence of a regulated production function

This paper examines the generalization of the regulated production function. It characterizes the set of admissible regulatory constraints that are compatible with the existence of a regulated production function in a sufficiently weak framework to encompass the usual rate-of-return constraints à la Averch and Johnson and value constraints.     

The Impacts of Technology, Trade and Outsourcing on Employment and Labor Composition

Empirical studies of skill-biased technological change are typically based on a simple production or cost function framework and limited information on technology and labor composition. In contrast, we simultaneously assess the impacts of trade, technology, and outsourcing on shifts in labor demand using a dynamic cost function framework and comprehensive measures of workforce composition and investment in technology. Our findings indicate that technological change has had the largest impact on changes in labor composition. However, the indirect impact of trade on shifts in employment augments its direct impact because trade stimulates computerization, which further exacerbates skill-biased technological change.     

Unfolding intensity function of a Poisson process in models with approximately specified folding operator

Quasi-maximum likelihood histogram sieve estimators of the intensity function of an indirectly observed Poisson process are studied. The setup differs from the standard one in that the exact form of the folding operator may not be known. Instead, approximate knowledge on its discretized version is available. Conditions for strong L ²-consistency are given and admissible discretization rates are studied. In non-folding problems, the number of histogram bins may essentially increase at the usual maximal rate while folding reduces the allowed discretization rates. It is shown that, even in moderately ill-posed problems, the discretization effects may be critical for the strong L ²-convergence and that there is an essential need both for further regularization and for imposing stronger conditions on the estimated function. Not surprisingly, the most restrictive factor is the low approximation power of piecewise constant functions. A regularization method is proposed which suitably modifies the discrete approximation of the folding operator and ensures the strong consistency. Since no penalty term is being introduced, the EM algorithm can be used in its factorized, efficient form. Convergence rates are obtained in terms of the discrete problem. Received: July 1999     

Estimating X-Efficiency in Taiwanese Banking Using a Translog Shadow Profit Function

A multiproducttranslog normalized shadow profit function is used to examineX-efficiency and related issues with respect to Taiwan's bankingsector. The model developed here is theoretically more appropriatecompared to that proposed by Berger, Hancock, and Humphrey (1993);as the former is obtained within the framework of profit maximization.Parameter estimates from our parametric translog profit functionare shown to be robust against different model specifications.More than half of all potential profits are estimated to be lostdue to economic inefficiency. The relatively more important roleof technical inefficiency, compared with that of allocative inefficiency,implies that deficient output revenues outweigh excessive inputcosts. Translog evidence indicates that larger banks tend tobe more technically efficient than smaller ones. The data showstrong technical progress during the sample period, while themodel failing to include X-inefficiency yields no technical advance.     

基于金融功能范式的社会主义新农村金融体系建构研究

农村金融体系建构和改革是社会主义新农村建设的重要内容和重要保障。实践证明,以往以机构范式为指导的农村金融改革忽略了对农村金融体系功能的关注,往往是以牺牲效率或违背市场发展方向为代价的。与社会主义新农村建设相适应的农村金融体系建构和改革,以社会主义新农村的需求为依据,明确了农村金融体系的功能定位,并在此基础上确定了农村金融体系的机构构成和各自的职能分工,以期为我国深化农村金融改革提供新的思路和有效的路径。     

开放条件下中国货币与经济关联度变动原因实证研究

本文运用动态条件相关(DCC)方法估计中国各层次货币与实体经济的关联度。研究发现,1994年前,关联度始终在低位波动,之后大幅提高,总体呈上升趋势。通过在模型中引入金融深化度和经济开放度,本文从不同的侧面解释了货币与经济关联度变动的原因。虽然金融深化度和经济开放度对关联度的影响程度随货币层次的提高而增强,但作用方向却不完全相同;金融深化度越高,经济开放度越低,关联度越强,这表明金融深化理论与中国国情相适应。这对于改革开放具有较强的现实意义。政府通过优先发展金融,深化金融体制改革,能够提高货币对经济增长的效能,促进经济结构的转型和经济持续增长。
