城市商圈布局的三维动态模型构建与述评 总被引:3,自引:0,他引:3
商贸产业是维系一个城市经济运转的原动力之一,城市商圈是这个经济发展动力的重要载体.本文在吸收西方经典商圈理论模型的基础上,结合我国城市商圈发展现状,从外部环境、内部成长和时间三个维度分析其影响因素,构建了城市商圈布局的三维动态模型,以期对城市商圈布局和城市经营提供一定的现实参考价值. 相似文献

良好的信用有助于经济的可持续发展,而我国目前被企业信用问题困扰。建议在企业信用数据库的基础上,实现信用资源共享来构建企业信用约束机制,形成失信者"一处失信、处处被动"的失信联防机制,来约束企业的信用行为。 相似文献

中国区域市场化进程的新特点——基于市场化指数的聚类分析 总被引:6,自引:0,他引:6
此项研究以2003年市场化指数测算数据为基础进行聚类分析,将中国各省区市场化发展程度分为高、中、低三类。通过分析和比较得出:东部地区内部市场化发展呈现分化状态,市场化程度较之中、西部地区内部更为离散;市场化程度较高的一类地区与市场化程度较低的三类地区市场化差距呈现拉大趋势。在市场化发展过程中,一、三类地区之间的要素市场化程度、贸易自由度差距悬殊,差距拉大速度递增,而在政府行为规范化方面差距较小。进一步细化指标还发现:人才创新能力在一、三类地区存在很大差异,极大地影响了第三类地区市场化发展水平,需引起人们关注。 相似文献

In this paper we use a large dataset to explore whether the liberalization of trade in services is beneficial for the international trade in goods. We find empirical evidence supporting this notion. We investigate which types of trade in services are more important for the international trade in goods and find that trade in transportation and communication services generate the largest impacts on trade in goods. We also investigate which types of trade in goods are likely to benefit from the liberalization of trade in services and find that, under the 2‐digit ISTC classification, all the categories are likely to exhibit a positive impact. 相似文献

A new framework is presented for the study of the existence and uniqueness of solutions to the Koopmans’ equation in the unbounded
case, that is based on the contraction mapping approach. In the bounded below case with bounded consumption streams, uniqueness
of the solution in the whole class of weak-star continuous utility functions is obtained. When the aggregator is unbounded
below and/or consumption streams are unbounded, existence of a weak-star continuous solution is shown, and a simple criterium
to check the sufficient conditions for existence is provided.

This paper presents a model of the interactions between natural resources and physical capital in the evolution of a tourist destination. The projected trajectory of the number of tourists approaches the classical lifecycle pattern. The post-stagnation phase is analyzed within the model, obtaining different patterns which depend on the impacts of physical capital on both demand and environmental degradation. The magnitudes of these impacts are determined by the type of tourism. An empirical application to the case of the tourist industry in the Canary Islands (Spain) is presented, showing that the model can represent the general characteristics of the post-stagnation phase of a tourist destination. 相似文献

Learning by doing,spillovers and shakeouts 总被引:1,自引:0,他引:1
Jim?Y.?Jin Juan?Perote-Pe?a Michael?TroegeEmail author 《Journal of Evolutionary Economics》2004,14(1):85-98
This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification:

Reinforcing the Link Between Contributions and Pensions: The Effect of the Population Aging 总被引:1,自引:0,他引:1
In this paper, we analyze a majority voting process on the earnings-related part of pension benefits in a Social Security system with flexible retirement. We show that the aging of the population may make it easier to implement one of the proposed reforms to achieve a delay in the average retirement age of workers, to reinforce the link between contributions and pensions. 相似文献
