关于规模经济的实证分析--以我国汽车工业为例

汽车工业不仅是产业关联度高、资金和技术密集度高的现代产业部门，而且也是规模效益明显的现代产业部门。它作为影响力大、带动力强的产业，对中国经济正产生着越来越大的影响。本文以经济学的规模经济概念为基础，运用有关规模经济的理论和观点，以我国汽车工业为典型，从四个方面对汽车工业规模经济问题进行了分析，并对实现规模经济性的方法和途径进行论述。     

Performance Measurement in Government Service Provision: The Case of Police Services in New South Wales

The NSW Government is implementing a financial framework which is designed to encourage government service providers to become more efficient and effective. NSW Treasury is using Data Envelopment Analysis (DEA) to measure the efficiency of major government service providers, such as police, courts and hospitals. This paper outlines the progress in implementing the new financial framework and illustrates the way NSW Treasury will use DEA to help improve the efficiency of government service providers by describing an analysis of the NSW Police Service. The results suggest that NSW police patrols (local police districts) could, on average, reduce input usage by 13.5 percent through better management, and by 6 percent if the patrols could be restructured to achieve the optimal scale. Results also indicate that differences in operating environments, such as location and socioeconomic factors, do not have a significant influence upon the efficiency of police patrols.     

DEA evaluations of long- and short-run efficiencies of digital vs. physical product “dot com” companies

This paper applies Data Envelopment Analysis to determine relative efficiencies between internet dot com companies that produce only physical products and those that produce only digital products. To allow for the fact that the latter are relatively inexperienced, a distinction is made between long- and short-run efficiencies and inefficiencies, with a finding of no statistically significant difference in the short run but digital product companies are significantly more efficient in the long run. A new way of distinguishing between long- and short-run performances is utilized that avoids the need for identifying the time periods associated with long-run vs. short-run efficiencies and inefficiencies. In place of “time,” this paper utilizes differences in the “properties” that economic theory associates with long- and short-run performances.     

The risk-return trade-off in human capital investment

In this paper, we analyze investments in human capital in a way which is standard for financial assets, but not (yet) for human capital assets. We study mean-variance plots of human capital assets. We compare the properties of human capital returns using a performance measure and by using tests for mean-variance spanning. Fields differ strongly not only in common rates of return, but also in return per unit of risk. We identify a range of educations that are efficient in terms of investment goods, and a range of educations that may be chosen for consumption purposes.

绍兴、吴江农村城市化的情况调研

通过对江苏吴江市和浙江绍兴县两地部分建制镇和部分原农村居民点的实地调研 ,作者认为 ,目前两地农村工业化、城市化处于发展的上升期 :中心镇经济和城市化发展相当快 ;中心镇以下的部分行政村异地或就地实现城市化。在城市化进程中 ,以下问题有待探讨解决 :迁村并点、撤乡并镇的速度与规模 ;城镇建设用地指标及相关政策 ;社区建设改造过程中 ,农民征地拆迁补偿标准和社会保障等。     

旅游项目风险因素分析的生态系统观点

旅游业是一个关联度大、相关带动性强的经济性产业,因此其风险因素众多.从创新生态系统视角-对旅游项目的风险因素进行分析,可以将这些风险因素分为三类,项目自身风险、项目依赖风险和资源整合风险.

基于能值分析的中国矿产资源可持续发展体系研究

可持续发展理论的研究,多是以环保为基础,促进经济增长的发展模式,是一种静态的发展理论.通过动态可持续发展的观点的提出,认为可持续发展包括生态资源环境发展、经济发展和社会发展3个组成部分,应把经济发展和社会发展建立在生态发展、资源发展和环境发展的基础上,把"重视环境保护"的静态发展观转变到"重视发展、环境保护为基础、发展是主题"的动态可持续发展观.并借助于能值分析理论,尝试探讨中国矿产资源的动态可持续发展的定量研究体系,为我国矿产资源的可持续发展提供政策建议.
