ANALYSIS OF A DYNAMIC RESIDENTIAL LOCATION CHOICE MODEL WITH TRANSACTION COSTS*

ABSTRACT. This paper incorporates transaction costs in a residential location choice model. An individual's choice is assumed to be an outcome of a two-stage process: a decision to change, or to undertake a transaction and, conditional on a change occurring, a choice of a new alternative. The dynamic choice model is aggregated to yield a Markovian model of residential location patterns. It is shown that recent contributions to dynamical urban modeling correspond to special cases of the deterministic version of this model. The Markovian model is used in a theoretical analysis of the influence of transaction costs on the properties of the stationary state. The effects of residential mobility rates and of interdependencies among individuals, caused by supply-side and density-related interactions, are also analyzed. It is shown how these dynamical factors modify the stationary state, thereby demonstrating the type of errors which may occur with static models that omit them.     

旅游产业部门结构合理性的SSM分析-以陕西省为例

为了寻求省域旅游产业发展的合理部门结构,利用偏离-份额分析法,以旅游统计年鉴提供的数据为基础,对陕西省旅游创汇部门的产业结构进行实证分析。研究表明陕西省各旅游创汇产业部门中,原有基础好,竞争力较强、具有部门优势的增长部门包括商品销售、邮电通讯和市政交通等部门;原有基础差但发展快,竞争力较好,具备一定部门优势的增长部门包括住宿、餐饮业等;基础较好,但竞争力较差的部门则包括长途交通运输业、观光游览、娱乐业等。论文针对各部门实际发展状况分别进行了分析,指出各自发展方向和策略。最后评价了偏离-份额分析法在旅游创汇部门产业结构分析中的应用效果,认为该方法具有较强的综合性和动态性,能够有效揭示旅游创汇各部门产业结构变化的原因和发展机制,是确定未来旅游业创汇部门发展主导方向的有效方法之一。     

LUTI模型原理、实现及应用综述

经济全球化背景下可持续发展已成为当今世界发展的主题。快速城镇化下的中国,城市空间的可持续性发展提上日程。为此,期待有力的、可操作的工具用于定量模拟城市空间演化过程、预测不同政策下城市空间的发展趋势,为城市化持续健康发展提供决策支持。本文分析了LUTI模型的基本原理、构建思路、实现框架和建立中国城市LUTI模型面临的问题,并回顾了国内外利用LUTI模型模拟城市空间演化过程,以辅助表明城市空间决策的研究现状,希望能为中国的城市空间可持续发展模拟分析研究提供参考。     

MUNICIPAL AMALGAMATION AND THE GROWTH OF THE LOCAL PUBLIC SECTOR IN SWEDEN*

ABSTRACT. The proposition that a decentralized structure of local governments can effectively constrain public sector growth is empirically investigated. Data on Swedish municipal sector size for the 1942–87 period are analyzed within the context of a median voter model. The results indicate that decentralization, measured by the number of units of local government serving a given population, constrains the influence of institutional factors (e.g., rent seeking, bureaucracy) on local budgets as long as these units exceed some minimal threshold size. The findings support the view that communities should be given the flexibility to determine their own ideal pattern of local governments.     

MOVING CENTRAL KNOWLEDGE TO A NORTHERN PERIPHERY: EXPLORING LOGICS OF PUBLIC SECTOR JOB RELOCATION IN SWEDEN

Through the means of Swedish relocation politics, the capital of Stockholm has been constructed as a governing centre with the ability of giving something to a periphery thought of as unable to survive on its own. The relationship between centre and periphery, furthermore, produces images of what kind of knowledge can be located to “central” or “peripheral” regions. In this article I research the move of a knowledge‐intense government agency from Stockholm to Östersund, a smaller inland town in the north. The data were collected through an ethnographic case study of a government agency. I adopt a discourse theoretical approach that provides a clear ontology of identity and processes of identification. This enables research on how ideological images of places create geographical identity positions. The aim of this article is to explore how groups of professionals at the government agency identified with geographical identities dependent on whether they were seen as experts or generalists. In conclusion, identity positions became important for how the relocation was organized. The establishment of the two identity positions functioned to stabilize the social environment during the move, a time when many things at work seemed to be in turmoil. At the same time the positions worked to exclude other ways of identifying with (work)place, and in this way sustained asymmetrical relations of domination and subordination between centre and periphery.     

公共交通可达性分析方法进展

公共交通可达性拥有空间属性、时间属性、社会属性和经济属性,它是一种衡量区位价值的综合性指标,不仅可以反映城市空间特征,同时对城市中生活的人的社会经济属性和生活习惯,具有一定的解释力。为了不断适应新形势下的交通发展要求,减少环境负担,早日实现低碳绿色发展,创新公交都市规划与分析方法迫在眉睫。本文对基于个人的、基于效用的、基于基础设施的和基于位置的可达性研究进行了回顾,并归纳了七种公共交通可达性的分析方法,分别为：基于缓冲区的公共交通站点可达性、基于供需模型的公共交通面状可达性、基于网络分析法的公共交通网络可达性、基于成本栅格法的公共交通可达性、基于成本栅格与网络分析的集成法的公共交通可达性、基于高性能图形数据库的公共交通高精度可达性、基于开放地图 API 的公共交通高精度可达性。 以期为我国未来公共交通可达性的分析方法提供指引和借鉴。     

LOCAL PUBLIC SERVICES COSTS AND THE GEOGRAPHY OF DEVELOPMENT: EVIDENCE FROM FLORIDA COUNTIES

Theory suggests that the spatial distribution of development within a local jurisdiction affects the costs of providing local public services. We use GINI coefficients to characterize these distributions at the county level and estimate the effects on real per capita expenditures from reductions in the spatial concentration of all buildings and nine alternative types of development. We also estimate the effect on expenditures from expansions in the developed area of a county. The results obtained from a panel of Florida counties confirm our theory and suggest that the geography of development within a county affects public services costs.
