变集体所有为公共所有的新型土地生产关系创制

创制一种新型土地生产关系的目的是为了超越责任制的局限，建立产权和经营权之间的有效连结机制，从而为城乡统筹意义上的共同富裕提供相应的经济基础。这种创制的基本途径是革新土地的集体所有制，并以由此而得到的产权落实为新型合作经济提供必要的资格保证。本文认为，创制新型土地生产关系包括设置土地委员会、实行产权的物权化，以及建立新型合作经济等方面的内容。     

扩内需 抗风险 保增长 促转型

2008年,美国次贷危机愈演愈烈,不仅仅美国国内经济下滑,而且导致主要发达经济体纷纷走向衰退,形成世界经济增长率大幅下降的态势。江苏经济继续高速增长,但世界经济下行压力不断加大,全年高开低走,并且面临继续回落的严峻挑战。总的对策思路,应是扩内需、抗风险、保增长、促转型,采取多种有效措施,防止经济大起大落,保持经济持续平稳快速增长,加快转变经济发展方式,提高经济运行的质量与效益,坚持科学发展,切实改善民生。

目的研究柴胡加龙骨牡蛎汤对艾滋病并发抑郁症免疫功能和生活质量的影响。方法采用汉密尔顿抑郁量表(HRSD17)筛查艾滋病抑郁症患者,柴胡加龙骨牡蛎汤干预治疗,用ELISA方法测量白细胞介素-2水平。用HIV/AIDS患者生活质量量表(MOS-HIV)评价生活质量。结果治疗组治疗前后IL-2和生活质量积分有统计学差异(P<0.05)。结论柴胡加龙骨牡蛎汤能改善艾滋病并发抑郁症患者免疫功能、提高生存质量,并且具有一定的抗抑郁作用。     

基于GIS的工商管理信息系统的设计与实现

由于我国的工商管理涉及的地域较为广泛,而且业务流程极其复杂繁琐,尤其是基层工商管理部门,面对的营业户口不仅数量巨大,而且区域也十分广泛。所以,这就对我国的工商管理信息系统提出了较高的要求,需要为工商管理部门提供完善而科学的管理。因此,可以通过GIS来进行电子信息管理。文中就如何设计出基于GIS的工商管理信息系统进行了讨论。

Water as an investment: liquid yet illiquid!

The water industry is in great need of further large investments to address existing severe water shortages worldwide which requires the participation of private sector investors. This industry is heavily infrastructure based and is therefore saddled with fixed assets-in-place or illiquid assets. This exposes the industry to what is termed as ‘illiquidity risk’, and hence, investors in this industry should be compensated for bearing this risk with an appropriate return premium (i.e. extra return). In this study, we provide evidence as to whether illiquidity risk indeed significantly affects returns in this industry. We examine the case of all 76 firms that compose the five major global water indices. After controlling for other factors that impact on returns, our results suggest that asset illiquidity is positively associated with stock returns. Specifically, water firms with a larger proportion of illiquid assets-in-place are observed to have greater stock returns than those with a smaller proportion of illiquid assets. Our results have important implications for the financing of water-related projects particularly those which involve the participation of investors from the private sector.     

农村集体建设用地流转地权的激励模式

农村集体建设用地流转中存在严重的资金时差悖论,导致难以利用集体土地本身进行融资,土地整理融资难反过来又成为阻碍集体建设用地流转的瓶颈性因素。现有流转模式难以协调各种利益,不能对流转各方产生足够激励,变相征地的方式削弱了农民的土地持续收益能力,未能真正实现城乡建设用地"同质、同价、同权"。因此,应根据利益协调的原则创新制度设计,以地权激励引导社会资源投入,促进集体建设用地顺畅流转。     

Learning by doing,spillovers and shakeouts

This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification: L11, L13, O31Correspondence to: Michael TroegeWe would like to thank Hans Mewis, Christophe Moussu and an anonymous referee for valuable comments and suggestions.
