Institutional design and the closure of public facilities in transition economies

As part of the reforms of their systems for financing and delivering health care, many transition economies, particularly in central and eastern Europe, have adopted national insurance funds that are institutionally separate from ministries of health. Most of these countries have also grappled with the problem of restructuring the delivery system, especially the need to reduce hospital capacity. Although improving the performance of medical care providers through a shift from passive budgeting to explicitly incentive mechanisms is important, why this change in financial relations between the government and providers could not be implemented simply by reforming the role of health ministries is not obvious. This paper presents an explicit rationale for the separation of powers between the regulator (the ministry of health) and the financing body (the insurance fund), based on the inability of a single agency to commit to closing hospitals.

It of fers more incentives than other oil-producing countries in the following four aspects: (1) Income tax has a "wide tax base and low tax rate"; (2) VAT levies a low tax rate on ma-     

绿色中药产业初见成效 发展任重道远——对汉中市部分中药产业重点发展县的调查

近年来,汉中市实施＂发展绿色产业,建设绿色汉中＂的战略,中药产业逐渐成为汉中经济发展新的增长极。为了解汉中中药产业的发展情况以及银行业机构金融服务支持情况,笔者先后深入勉县、留坝、佛坪等中药材生产形成一定规模的县域,采取与当地政府部门、银行业机构座谈,深入农户中药材种植基地和实地察看加工企业等方式进行了专题调研,分析了其中问题并提出相关建议。     

Optimising a Probabilistic Model of the Development of Play in Soccer

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social, 16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations. However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed. This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained a probabilistic model of the development of play in soccer is proposed.     

产业链概念及其形成动力因素浅析

近年来,有关产业链研究显著升温,但学术界对产业链定义及形成动因还没有形成一致认识。文章从企业追求自身长远利益最大化的角度给出产业链定义,然后分别从内因和外因分析产业链形成的动力因素。其中,内部动力因素包括“降低交易费用”、“风险规避”和“创造和利用社会资本”;外部动力因素包括“区位优势”、“技术进步”以及“政府产业政策”。

物流产业集群共生发展影响因素实证研究

文章根据物流产业集群发展的实际,以共生理论为基础,从资源集聚、分工合作、资源共享三个维度构建物流产业集群共生发展影响因素结构方程模型,进而对影响物流产业集群共生发展的关键因素以及这些因素之间的关系和强度进行实证检验。研究结果表明,物流产业集群的资源集聚能力、分工合作水平、资源共享能力对物流产业集群共生发展具有正向影响,它们对物流产业集群共生发展的影响和作用由大到小依次为:资源共享能力、分工合作水平、资源集聚能力。在物流产业集群演化发展的过程中,提高物流产业集群共生体的资源集聚程度,提高集群共生单元间的分工合作水平,增强集群共生体的资源共享能力,都将促进物流产业集群的共生发展。
