我国水权交易制度变迁及交易市场中政府的角色定位

我国现行水资源使用制度的不完善致使水资源的利用矛盾重重,面临的是一种“内卷”问题,这要求我们探索建立一种新的水权制度。水权是用水主体依法取得的基于消费性用途的配水量权,针对该水权概念,水价只是水产品价格中的资源水价。水权制度本身的型构是一个缓慢地演进、发育和成型的过程,而并非只是一个国家简单设立、界定和实施的短期过程。所以,政府的行为须谨慎。

房地产企业盈利能力与土地储备战略的关系分析

土地储备战略是房地产企业经营战略的重要一环,不同的土地储备战略将直接影响房企未来的项目开发和当期的盈利能力.对于上市房企来说,合理的土地储备战略必须既满足项目开发需求又能维持一定的资金回笼速度.本文以万科、金地和保利三家房企为研究对象,以2002年至2011年作为研究期,结合房地产市场的运营情况,对三家房企的土地储备战略和盈利能力做出了横向和纵向对比分析后认为:房地产企业盈利状况和土地储备数量既有相互促进作用又有彼此制约的关系,不同产业周期下房企需根据情况调整土地储备战略而非一味争夺土地资源.     

基于角色视角的分享经济信任机制研究

基于信任理论,从不同角色视角探究各信任要素对分享经济行为意图的影响。通过构建分享经济信任机制概念模型以及实证检验发现：从需求方视角来看,对个体（供给方）3个维度（能力、正直和善意）的信任、对平台善意的信任以及对产品能力的信任对需求意图产生积极地影响。从供给方视角来看,对个体（需求方）能力的信任和对平台3个维度（能力、正直和善意）的信任对供给意图有正向的影响。需求方更关注人与人之间的信任,而供给方则更看重对平台的信任。通过进一步比较还发现,需求方对平台和个体（供给方）的信任聚焦于善意信任,但供给方则是侧重于对平台和个体（需求方）能力的信任。     

卡脖子技术协作攻关的政府择优支持制度研究

卡脖子技术是一种人有我无受制于人的共性技术,政府支持对其协作攻关必须以择优制度为保障.由于卡脖子技术是一种可对标的特殊共性技术,因而政府择优支持制度具备择优条件,可以有效防范支持制度的政府失灵.政府择优支持制度包含择优技术标准、信息共享、测试平台共享等制度,有利于形成科学技术路线、释放优秀方案潜力,从而降低协作成本、提升合作收益、激发创新投入、实现高效攻关.对科研机构和生产企业攻关协作的博弈模型论证了上述观点.     

Extending the link between entrepreneurial self-efficacy and intention: a moderated mediation model

This study extended the research on the relationship between entrepreneurial self-efficacy and intention by developing a moderated mediation model. This model posits that the link between entrepreneurial self-efficacy and intention is mediated by attitudes toward entrepreneurship and planned entrepreneurial control, and that these mediation processes are further moderated by subjective norms. Based on a sample of 308 valid responses, regression analysis yielded two noteworthy results. First, entrepreneurial self-efficacy positively affects intention through attitudes toward entrepreneurship and planned entrepreneurial control. Second, the direct effect of entrepreneurial self-efficacy on intention decreases as subjective norms increase. By contrast, the indirect intention effects of entrepreneurial self-efficacy through attitudes toward entrepreneurship and planned entrepreneurial control increase as subjective norms increase. In addition, the results indicated that subjective norms positively affect entrepreneurial intention. These findings indicated that the model advances the use of the theory of planned behavior and can be used to define a person as an entrepreneur.     

论公正及其与自由、平等的关系

尽管学术界对自由、平等和公正问题有许多研究和阐释,但较少将自由、平等与公正问题联系起来从总体上进行考察和研究,以致关于自由、平等和公正及其关系问题成了人们最说不清、道不明的问题。本文试图立足于当代人类社会现实及其走向,着重从与自由、平等相互关联的视角研究公正问题,力求纲要性地对公正及其与自由、平等之间的关系提供一些阐释和见解,最终论证这样一种基本观点:现代公正是一种综合性的价值要求,它要求社会自由和平等,也要求对自由和平等可能导致的社会问题给予适当解决。

Pre-positioning hurricane supplies in a commercial supply chain

Inventory control for retailers situated in the projected path of an observed hurricane or tropical storm can be challenging due to the inherent uncertainties associated with storm forecasts and demand requirements. In many cases, retailers react to pre- and post-storm demand surge by ordering emergency supplies from manufacturers posthumously. This wait-and-see approach often leads to stockout of the critical supplies and equipment used to support post-storm disaster relief operations, which compromises the performance of emergency response efforts and proliferates lost sales in the commercial supply chain. This paper proposes a proactive approach to managing disaster relief inventories from the perspective of a single manufacturing facility, where emergency supplies are pre-positioned throughout a network of geographically dispersed retailers in anticipation of an observed storm's landfall. Once the requirements of a specific disaster scenario are observed, supplies are then transshipped among retailers, with possible direct shipments from the manufacturer, to satisfy any unfulfilled demands. The manufacturer's pre-positioning problem is formulated as a two-stage stochastic programming model which is illustrated via a case study comprised of real-world hurricane scenarios. Our findings indicate that the expected performance of the proposed pre-positioning strategy over a variety of hurricane scenarios is more effective than the wait-and-see approach; currently used in practice.     

基于自适应控制的区域生态经济协调发展构想

借鉴自适应控制理论的基本思想,建立了包括区域生态经济系统、协调发展评价系统、决策机构及调节系统4大基本要素组成的区域生态经济协调发展总体框架,它具有反馈作用,能根据区域生态经济系统的实际情况自动调节和控制其协调状况,并就此提出了区域生态经济管理的新理念,最后给出相应的建议。
