江,浙两省三资企业综合效益分析与评价

本文的研究主要结合对江、浙两省173(江苏100家,浙江73家)家三资企业的调查情况,采用定性与定量相结合的方法,力求真实、准确地反映三资企业的综合效益。 综合效益分析与评价,就是在统计分析的基础上,对三资企业生产经营活动中的各种活动进行分析与评价,建立三资企业综合效益评价的指标体系。综合效益分析包括:(1)企业基本状况分析;(2)技术进步水平分析;(3)经济收益水平分析;(4)投资环境影响分析;(5)创汇节汇能力分析。     

水电站引水隧洞钢衬砌的压曲

采用数值模拟技术，对水电站引水隧洞的钢衬砌在外水压力作用下直到破坏的结构性能进行了研究。在数值模型中采用了真实条件来考虑逐渐的弹塑性压曲和与周围介质（混凝土和岩石）的接触条件的改变。研究了各种参数（如原始缺陷，加劲件类型和间距，钢材等级等等）的影响，同Jacobsen法作了详细比较，展示了该方法的有效性和限制。     

Empirical Analysis of Wealth Distribution Disparity of Chinese Residents and Its Changes

I. Introduction The widening wealth gap between the rich and the poor is currently becoming a focus of attention in China.

对挪威高压混凝土封堵体的评论

早在1987年至1991年挪威就对高压封堵体的设计，施工和运行进行了研究。搜集和分析了30多个承受静水压力水头1000m以下的封堵体的详细资料，认为混凝土结构长度应取静水压力的2%～5%，而钢衬长度只能取压力水头的0.4%。1980年以来，各种资料证明在降低封堵体的透水性方面取得了技术进步。     

Taxation Policies Adjust,Motor Vehicles Boost

In recent years,Chinese automotive industry,as one of the pillar industries has kept on rising.In 2006,Chinese auto production ranked the third in the world. The governmental authorities are also studying the corresponding taxations to boost the healthy development of Chinese automotive industry. Mr.Shi Yaobin,Chief-Director of Taxation Department, the Ministry of Finance of ER.C,gave a lecture on current taxation items in China's auto industry and released infor-     

The Economic Impact of AIDS Treatment: Labor Supply in Western Kenya

Using longitudinal survey data collected in collaboration with a treatment program, this paper estimates the economic impacts of antiretroviral treatment. The responses in two outcomes are studied: (1) labor supply of treated adult AIDS patients; and (2) labor supply of individuals in patients' households. Within six months after treatment initiation, there is a 20 percent increase in the likelihood of the patient participating in the labor force and a 35 percent increase in weekly hours worked. Young boys in treated patients' households work significantly less after treatment initiation, while girls and adult household members do not change their labor supply.
