产权制度与按要素贡献分配原则

社会财富分配原则的确定是由这个社会的财产产权性质和结构状况决定的。它不仅决定了收入分配的尺度,也影响了收入分配的方式和收入差异的大小。我国正在实施的按要素分配原则是与我国社会主义市场经济条件下不断变革的产权制度相适应的,但是,要有效地贯彻这种收入分配原则,还需要进一步加强产权制度立法与产权保护。     

村庄公共权力:村治研究的切入视角及其解说模式

村治研究的重心从民主问题转向治理问题引发了学术界的激烈争论,研究村庄公共权力则是搭建学术对话平台、消解学术分歧的重要突破口。以村庄公共权力为村治研究的切入视角,不仅有着特定的村治研究意义,而且具有明显的现实价值取向。国家与社会关系框架作为村庄公共权力研究的传统解说模式,因其解释空间的有限,难以将村治研究继续推向深入。借鉴并运用治理理论解说模式,是深化村庄公共权力研究的理想选择。     

京津冀区域近十年来人口分布格局研究—基于空间数据探索性分析方法

应用探索性空间数据分析方法对京津冀2000年到2010年人口空间格局进行研究,结论表明十年间人口聚集性在增加,主要原因是北京对人口吸纳的极化效应在增强,天津极化效应还没有表现出来。京津冀地区内部必须缩小发展差距,否则人口聚集的极化效应将更加突出,最终影响京津冀区域发展的可持续性。     

改革开放后我国经济增长与发展理论的演进轨迹

1978年以来,伴随着经济体制的转变和经济市场化的深入,我国的经济增长与发展理论自身也有了重要的发展。一方面我国学者在一定程度上历史地实现了理论研究范式的转换;另一方面初步形成了关于经济增长与发展理论的相对独特的研究内容与风格。这一理论的发展脉络可以简要概括为:速度理论→优先增长理论→增长方式理论→周期与波动理论,它说明我国经济发展理论逐渐由零散向系统化发展、由浅层次向深层次发展、由本土化向国际规范化发展的演变趋势。     

On the sample characterization criterion for normal distributions

Conventionally, it was shown that the underlying distribution is normal if and only if the sample mean and sample variance from a random sample are independent. This paper focusses on the normal population characterization theorem by showing that, if the joint distribution of a skew normal sample follows certain multivariate skew normal distribution, the sample mean and sample variance are still independent.     

关于农村信用社模式改革的思考

农村信用社经过多年的改革许多省份都选择了省联社的模式，在这种模式下的农村信用社有许多缺点。为了避免这些缺点，许多人建议将农村信用社改组为农村商业银行。但如果再建立省级农村商业银行容易使农村地区更难得到贷款的支持，所以建议在农村信用社下一步的改革中设立两级的农村商业银行。     

An EOQ inventory model for items with Weibull distribution deterioration,ramp type demand rate and partial backlogging

In this paper, an EOQ inventory model is presented depleted not only by demand but also by Weibull distribution deterioration, in which the demand rate is assumed that with a ramp type function of time. In the model, shortages are allowed partial backlogging and the backlogging rate is variable and is dependent on waiting time for the next replenishment. The method is illustrated by three numerical examples, and sensitivity analysis of the optimal solution with respect to parameters of the system is carried out.     

Estimation of the means of the bivariate normal using moving extreme ranked set sampling with concomitant variable

The estimation of the means of the bivariate normal distribution, based on a sample obtained using a modification of the moving extreme ranked set sampling technique (MERSS) is considered. The modification involves using a concomitant random variable. Nonparametric-type methods as well as the maximum likelihood estimation are considered. The estimators obtained are compared to their counterparts based on simple random sampling (SRS). It appears that the suggested estimators are more efficient. Also, MERSS with concomitant variable is easier to use in practice than the usual ranked set sampling (RSS) with concomitant variable. The issue of robustness of the procedure is addressed. Real trees data set is used for illustration.     

The Impact of Product Returns and Retailer's Service Investment on Manufacturer's Channel Strategies*

We study the distribution channel decision of a manufacturer who considers whether to add an online channel (direct channel) to its brick‐and‐mortar retailer (indirect channel). The retailer faces the opportunity to invest in store assistance to help consumers choose products and thus reduce product returns. Special attention is given to the impact of product returns and retailer's store assistance investment on manufacturer's dual channel decision. We examine conditions under which the manufacturer uses dual channels and how various relevant factors affect its channel decision under two settings, depending on whether the retailer has its own online store or not. When the retailer does not have its online store, we find that (i) the addition of the direct channel raises the wholesale price; (ii) the direct channel addition hurts the retailer if the nonreplacement rate is low; (iii) the manufacturer has a lower incentive to add the direct channel when the retailer's service cost is lower or its returns reduction rate from service investment is higher; and (iv) the manufacturer should treat its own returns handling cost as a key factor in its channel structure decision. In addition, when the retailer operates an online store, we find that the manufacturer may have an incentive to add a direct channel such that both firms own direct channels.     

收入分配、技术进步与经济的持续增长——来自中国的经验

支撑中国经济近30年高增长的主要是要素投入而非技术进步,这种粗放型的增长方式以及这种方式下的经济增长都是不可持续的。中国经济发展正在进入"刘易斯转折区间",这可能为经济增长方式转变为主要依靠技术进步提供条件,也可能使经济进入均衡陷阱。技术进步本身有着内在的逻辑,它源于分工,而分工又具有自发演进的正反馈机制。建设"创新型国家"(或者说大范围的技术进步)难以依靠由政府动员全社会力量集中攻关的"举国体制"来实现,分工的深化才是技术进步,进而是经济持续增长的决定性因素。
