“五水共治”的体制、机制、制度创新

"水危机"的本质是制度危机。针对"多龙治水"弊端要加强部门整合和统筹,针对"条块分割"弊端要加强"条"的功能和"块"的责任,针对"单打一"决策弊端要加强科学的综合决策,针对"运动员"与"裁判员"合一弊端要建立第三方检测体制。水资源配置和水环境保护往往面临政府失灵、市场失灵和社会失灵,因此,必须加强政府机制创新、市场机制创新和社会机制创新,同时加强三大机制的相互制衡机制的构建。"五水共治"需要制度体系的保障。制度体系包括管制性制度、经济性制度和社会性制度。不同制度之间可能存在替代性关系,也可能存在互补性关系。替代性制度要进行优化选择,互补性制度要进行组合强化。"五水共治"的制度创新不仅要加强制度体系的建设,而且要重视实施机制的建设。只有实施机制建设并落实到位,才能发挥制度绩效。因此,必须加强水污染举报机制、水环境监测机制、水生态评价机制、治水绩效考核机制、治水工作奖惩机制等实施机制的建设,并将这些机制逐一付诸实施。     

FDI对我国地区金融增长的非线性影响及其区域间差异

利用2001-2010年省级面板数据,分别考察外商直接投资对中国各区域金融增长的影响。研究结果发现：FDI对中国金融增长的影响是非线性的,且存在区域差异效应。根据中国区域经济和金融发展存在明显梯度差异的特性,提出了FDI对区域金融增长的倒“U”型假说。建议各地区根据本地区金融和经济发展程度差异的实际情况采取不同引资政策。     

中国养老保险制度对城镇居民消费的影响--基于OLG模型和2012年中国省际横截面数据的实证分析

通过建立世代交叠模型探讨我国现行基本养老保险制度对城镇居民消费的影响,指出在现行的现收现付制和完全基金制混合模式下,养老保险对居民消费的影响是有两种不同的效应：人口年龄结构的变化和资金成本的变化。尤其是人口老龄化会改变制度约束从而抑制消费。根据2012年中国省际横截面数据实证分析说明,城镇离退休人员养老金支出对城镇居民消费具有负面影响,说明人口老龄化可能已经开始削弱养老保险制度的社会保障功能。     

“企校所”模式继续教育质量评价研究

本文根据熵值法的客观性和模糊综合评价法的模糊性,在有不确定因素的情况下,提出了对"企校所"模式继续教育质量一种新的评价方法:熵值——模糊评价法。这种方法在一定程度上消除了模糊综合评判法中隶属度来源的主观性,使评价结果更符合客观实际。     

小城镇产业发展问题与对策探讨——以“中国山核桃第一镇”为例

推动小城镇发展与特色产业发展相结合是国家新型城镇化规划要求。特色产业助推小城镇发展已成共识,国内学者对此大有研究并取得相关成果。通过对"中国山核桃第一镇"产业发展的现状及存在问题分析,从山核桃产业链前中后端对山核桃产业存在的问题进行梳理,引鉴"公司+基地+农户"理念提出应对策略,促进小城镇健康发展。     

Real-World Economics Today:The New Complexity,Co-ordination and Policy

More realistic economics has to start out from the most basic socio-economic phenomena and processes, i.e. dilemma-prone interdependencies and strong uncertainty among agents that have become ubiquitous phenomena in the world today. In the reality of the “new” economy these are represented by functional and spatial fragmentation of value-added chains, global de-regulation and disembedding of the most powerful economic agents, on one hand, and increasing complexity and high integration of goods and services and net-based tele-IC-technologies on the other hand. All these rather new phenomena entail ubiquitous actual or potential co-ordination failure, either in the form of conventional “market failure”, with a complete mutual blockage of action, or of “wrong” co-ordination, or technological “lock-in”. Both forms are indicative of an insufficient capacity of the co-ordinated action required. In contrast, capability of sustainable innovative action in a broad sense requires new forms of co-ordination beyond “market” and “hierarchy”. Economics thus has to be defined more than ever as a science of effective co-ordination and the generation of innovative and sustainable collective action capacity. The global corporate economy has developed individualist arrangements to cope with that new co-ordination problem, such as local clusters and hub&spoke networks, which all have severe shortcomings. Against this background, the paper develops a setting with ubiquitous direct interdependencies, net-externalities, “strategic” strong uncertainty and ubiquitous (latent) social-dilemma problems. It discusses the possibility of an ideal decentralized and spontaneous co-ordination through emergent institutionalized collective action, specifically of “well-governed” network co-operation. In conclusion, it is argued that only a hybrid system of networks together with a new public policy role, supporting collective learning and emergent institutional co-ordination, i.e. an “interactive” and “institutional” policy approach, is capable of solving the co-ordination problems of the “new” economy.     

人民币国际化进程中的风险防范

随着跨境人民币交易范围和数量的迅速扩大,人民币国际化进程加快。境内人民币与境外人民币之间如何建立“防火墙”,防范围际投机资本的攻击,成为亟待解决的问题。境外人民币流出入通过设立“外汇人民币”账户可以与境内人民币分离,便利对境外人民币的统计监测,区分和掌握人民币基础货币在境内和境外的分布状况和变动情况,起到预警作用,也便于货币政策的稳健运行。与之配套的措施是建立健全境外人民币清算体系,将“外汇人民币”纳入国际收支统计分析及外债统计管理范畴。     

Developing Country Perspectives on Country-of-Origin Effects: The Case of the Proudly South African Campaign

ABSTRACT

Research on the effect of product country of origin (COO) also referred to as “made in campaigns” or “buy national campaigns” has attracted considerable attention from international marketing theorists for the past 40 years. This paper examines how the Proudly South African (PSA) initiative in the context of the global debate on the relevance of the concept of country of origin/buy national campaign/made in campaigns has been developed. Reference is made to other international campaigns such as Made in USA and Buy New Zealand and to the importance of the concept as a cue in the purchase decision-making process of consumers.
