清末“急务”与“本源”的失调——以鸦片禁政期间的财政窘况为背景

清末新政时期的编练新军和振兴实业分别被谕旨称为“急务”和“本源”,这是新政时期国家振兴的重要国策。两项国策的推行均需要有大量的财政投入。由于推行鸦片禁政,国产和进口鸦片税厘大幅度缩减,影响了中央和地方财政的拓展。在清廷的督催下,练兵新政不断得到强化,成为中央和地方财政支出的大项,这必然导致振兴实业因缺少足够的资金注入和宽松的税收环境而举步维艰。尤其是在制定国家预算的过程中,海陆军经费占据了国家财政预算相当高的比例,振兴实业这一国策在财政预算中并未明显地体现出来,形成了练兵“急务”突出,而实业“本源”却不断弱化的现实,两者在财政困绌条件下事实上处于“失衡”状态。朝野各方由此对军政失调、过分突出军备的倾向颇有微词,尤以各种报章的批评言论最为尖锐,国外人士对清廷推行新政中本末倒置现象的批评性观点也通过各种途径体现出来。清亡的原因也可借此得到一定的解释。     

间歇开放系统的可靠性分析与数值计算

研究了一种新型的可靠性系统，即间歇开放系统。在建立数学模型的基础上，我们详细分析了系统有关的可靠性问题，不仅获得时刻ｔ系统失效的概率和（０，ｔ］中系统失效的平均次数的瞬态解，而且也获得其平稳结果。最后用数值计算比较了间歇开放系统和经典系统的差别。     

Physician executives: where they are and what they do

As hospital operations become increasingly complex, so does the institution's management and organizational structure. Physician executives with titles of medical director, vice president for medical affairs, medical administrator, chief of staff, medical staff president, etc., are playing more important roles than ever before. This article will briefly review some recent literature describing physician executive profiles. The results from a survey of ten university teaching hospitals are also presented as supplementary information regarding current staffing models. Finally, several physician executive staffing-related issues will be discussed in light of the literature and the survey results.     

A survey of the family planning work done in Dongguan County

The total fertility rate of women of childbearing age of Dongguan County in China has been decreasing gradually from 5.9 during the period following the liberation in 1949 to 2.05 in 1982. In order to encourage young couples to implement the policy of family planning consciously, the people's government of Dongguan county decided in July 1980 that all cadres and employees in county towns who received 1-child certificates would be exempted from house rent of 45 square meters from the time they get their certificates and would be allocated a living space of a 2-children family until their children reached age 16. It also stipulated that every couple could enjoy 1 month's holiday every year for 3 years and during the holiday, their salary, bonus and rate of attendance would not be affected. Because women bear less children today, they are relieved from heavy household chores and become the main working force in collective production. As a result, the development of town-run enterprises was stimulated and the total industrial output value of these enterprises increased. The average monthly salary of each female worker is about 100 yuan. In 1984, the average income per capita of the country rose to 649.2 yuan. The implementation of family planning work has eased the tension in the education field. Previously, because of the large number of school-age children in rural areas, teachers had to teach 2 classes. In the past 4 years, great emphasis was laid on intellectual investment. During this period, 2351 schools were built and several fundraising projects were implemented. Since 1981, more than 200 new running water projects were built, and new public services have been developed, including old age homes.     

A case study of the labour market status of recent mainland Chinese immigrants,metropolitan Toronto

"This article focuses on an analysis of the labour market status of recent MCIs [mainland Chinese immigrants to Canada], taking into account such factors as gender, educational attainment, language proficiency and period of arrival (or length of residence in Canada), and uses Metropolitan Toronto as a case study. The effect of each factor on MCIs' labour market status will be analysed separately, followed by two logit models examining the simultaneous effects of the factors and their relative importance."

中国A、H股市场分割的根源分析

按照投资者的身份不同,中国的股票市场可分为A、B、H股三个市场,三个市场处于严重的分割状态,其最显著的表现就是A、B或A、H股双重上市公司股票的价差现象。本文拟以A、H双重上市股票为例,深入分析价差产生的原因,揭示中国股票市场分割产生的根源。     

市场定位战略的综合模型研究

本文构建了帮助企业界定有竞争力的定位战略的综合模型,即市场定位方法的钻石模型.本文认为,定位涉及三个关键任务:(1)准确识别目标顾客的需要并确定定位的外延或范围;(2)明确企业在定位主张中强调的顾客收益和价值;(3)制定相应的4P战略以支持定位主张.因此,市场定位需要沿着三个维度展开:(1)制定定位战略的程序;(2)在程序维度的每个具体步骤上需要完成的核心任务;(3)任务维度的每个具体举措所涉及的4P范畴.钻石模型就是整合了这三个维度的理论框架.本文对钻石模型的理论优势和对营销实务的指导作用进行了实证检验.
