征收和出让土地中政府干预对土地配置效率影响的定量研究

研究目的:定量评价征收和出让土地中的政府干预对土地资源从农业用地转为城市建设用地的配置效率的影响。研究方法:建立包含征收、一级出让和二级转让的多市场均衡模型,并进行实证研究。研究结果:1999—2005年征收和出让土地中的政府干预造成江西省鹰潭市农地资源被城市建设用地过度占用达183.48 hm2,占总非农化面积的33.73%。研究结论:征收和出让土地中的政府干预造成农地过度非农化,致使农村和城市土地利用效率的降低。     

基于客户价值的营销资源分配和关系管理研究

以客户价值和客户关系阶段二项指标为客户营销资源分配基准,结合客户关系管理的三项主要任务：新客户获取、高价值客户保持和危险客户赢回,提出了“以客户为中心”的资源分配整体框架,以及基于客户关系管理三项主要任务的资源投入最优比例模型。根据对不同客户关系阶段特点的分析,应该采取发展阶段、成熟阶段和衰退阶段关系管理策略。

Gender, self-employment and microcredit programs An Indonesian case study

Credit is often the missing link for low-income families that try to make a living by operating small microenterprises. At the same time, the presumption that lending to the poor is very risky, the costs of operation are high, and the low repayment rates for such loans limit bankers’ willingness to extend credit to the poor. This article, however reports on the results of a microcredit program in Indonesia which suggests that when agencies, government and non-government, in a developing country make credit available to low income women, they can reduce the costs of delivery, greatly increase repayment rates, and substantially improve the well-being of poor families. Other studies also suggest that such credit tends to increase women’s participation in decision making, reduces fertility, substantially improves household nutrition and raises aspirations for children’s education. Our case study cofirms these results.

中国专利对经济增长方式影响的实证研究:1988～2008年

运用我国1988~2008年省级面板数据,以全要素生产率体现经济增长方式,考察不同类型专利对经济增长方式的影响,结果凸显以1997年为断点的阶段性差异。实证结果显示,发明专利在1997年前对全要素生产率没有显著影响,但在1998~2008年对全要素生产率的影响远大于实用新型和外观设计专利,论证了原创型创新对现阶段我国经济增长方式转变的重要性,这与现有研究的结论不同。     

TOTAL FACTOR PRODUCTIVITY ESTIMATION: A PRACTICAL REVIEW

Abstract This paper aims to provide empirical researchers with an overview of the methodological issues that arise when estimating total factor productivity at the establishment level, as well as of the existing (parametric and semi‐parametric) techniques designed to overcome them. Apart from the well‐known simultaneity and selection bias, attention is given to methodological issues that have emerged more recently and that are related to the use of deflated values of inputs and outputs (as opposed to quantities) in estimating productivity at the firm level, as well as to the endogeneity of product choice. In discussing the estimation procedures applied in the literature, attention is given to recent developments in the field. Using data on single‐product firms active in the Belgian food and beverages sector, the most commonly applied estimators are illustrated, allowing for comparison of the obtained productivity estimates by way of a simple evaluation exercise.
