新战略背景下城市经济发展状况测度研究——基于融合社会网络的实证分析

当前,我国经济已转向高质量发展新阶段,国家对此出台了包括高质量发展、城市群协同发展及健康中国等多项战略规划,为未来城市经济发展指明了新的发展方向。本文在分析这些战略对城市经济发展要求的基础上解读了城市经济发展新内涵,构建了涉及数量、质量和效率三个方面,包含创新发展、协调发展、绿色发展、开放发展、共享发展和城市群支撑作用等10个维度,共44个三级指标的城市经济发展状况测度指标体系,同时就城市群支撑作用方面指标给出了融合社会网络分析的指标定量测度方法。本文构建的指标体系可全面监测我国城市在经济新战略背景下的经济发展状况,所提出的指标测度方法可定量测度城市所属城市群对城市经济发展的贡献,为相关战略下城市测度体系的建设与完善提供一定参考。     

长株潭城市群社会保障体系建设：问题与对策

建设统一的社会保障体系应是长株潭城市群建设的重要内容.当前,长、株、潭三地在社会保障领域与建设两型社会,统筹长株潭城市群发展还有一定的距离,有很多问题亟待解决,如农村社保是整个社保领域中的薄弱环节、管理体制分散政出多门、社会保障体各部分问题众多等.因此,建设完善的长株潭城市群社会保障体系,首先要确立长株潭城市群社会保障体系发展的思路和原则;其次,需整合社保工作机构,提高社会保障管理服务水平;第三要贯彻统筹发展原则,构建完善的社会保障体系.     

长株潭“3＋5”城市群土地集约利用评价研究

在分析城市土地集约利用的概念与内涵的基础上,结合城市群实际情况,首先构建长株潭城市群土地集约利用指标体系,然后利用模糊数学方法构建城市土地集约利用评价模型,据此对长株潭3+5城市群土地集约利用水平进行定量测定。研究结果表明:除长沙市和岳阳市处于基本集约外,城市群其它各城市及城市群整体的土地集约利用水平较低;城市群土地集约利用水平在时间上呈现总体上升趋势;城市群土地集约利用水平的区域差异明显,并与区域经济的差异高度相关;影响土地集约利用水平的因素涉及人口、资源、环境、经济与社会等各个方面。     

Product Positioning and Pricing Under Production Cost Considerations*

A framework in a competitive environment is proposed that incorporates production cost and economies of scale in the problem of positioning a product for a market segment. The model facilitates the existence of a Nash equilibrium in prices and product positions. As such, firms can simultaneously choose prices and product positions for the segment. This result improves the traditional theory on equilibria points in prices and product positions where firms choose their product positions first and then set their prices. A sensitivity analysis demonstrates the effects of changes in the unit savings derived from economies of scale or the cost of furnishing a product with its attributes by one firm on the product positions, prices, and profits of all competing firms. More important, the paper examines the effect on prices and profits of competing firms when one of the firms repositions its product closer to the segment's ideal point. It is shown that under certain conditions, the profit of a firm may actually decrease as it redesigns its product closer to the segment's ideal point. These conditions assist management to identify the product design beyond which enhancements of the product would lead to lower profits because of increasing production costs. It is also shown that the price of this firm increases. Past research supports the idea that positioning a brand closer to the ideal point, given fixed product positions of competing firms, would lead to greater buyer preferences and eventually higher profits. The price and profits of the competing firm may increase or decrease. Conditions are derived under which a movement towards the segment's ideal point by one firm would lead to higher profits by the competing firm.

基于EG指数的中国旅游产业集聚研究

集聚状况是旅游产业发展的重要表征,对于制定旅游产业发展政策、促进旅游产业发展具有重要意义。本文采用EG指数法,从区域和部门两个层面分别对2000-2008年我国旅游产业集聚程度进行了定量分析,重点阐释了我国旅游产业集聚程度变化的趋势及原因。研究显示：集聚程度随旅游产业发展阶段不同发生变化;由于旅游产业的特殊性,不能将集聚程度的提升作为旅游产业发展的目标,应该处理好阶段性集聚和扩散的关系;区位条件和外部环境因素会影响会集聚程度变化趋势。     

Inflation targeting and its spillover effects on financial stability in emerging market economies

In this paper, we study whether adoption of inflation targeting monetary policy framework has spillover effects on financial stability in emerging market economies. Working with data for 64 emerging market economies, we develop financial stability and sector specific stability indices and identify the effect using dynamic panel data models in difference-in-difference framework. We find significant positive spillover effects of inflation targeting adoption on banking system resilience and external capital inflows arising from improved transparency and accountability of the central banks. Based on the results, the paper recommends to emerging market economies which are currently under inflation targeting lite regime, to adopt full-fledged inflation targeting monetary policy.

经济集聚机理的尺度分异整合及其应用价值研究

经济活动空间集聚是有尺度之分的。文章从企业—厂商、产业—行业和区域—地带三个尺度研究了经济活动空间集聚,认为在企业—厂商尺度上,空间集聚特点是企业增长和空间扩张,作用机理是内部规模经济和内部范围经济;在产业—行业尺度上,空间集聚特点是企业的空间邻近性,作用机理是外部规模经济和外部范围经济;在区域—地带尺度上,空间集聚特点是产业的区域复合,作用机理是区域外部规模经济。在此基础上,文章论述了经济活动空间集聚的不同尺度作用机理的内在统一性及其理论的实践价值。
