是土地供应量与房地产税赋提高了房价吗

自分税制实施后,“土地财政”成为我国地方政府获取收入以支撑财政支出的主要选择,而与此同时房价也在不断上涨。中央政府从民生角度要求地方政府对房价实施调控,地方政府则主要通过调整土地供给量和房地产税税赋来施加影响。土地供应量和税赋会影响供需双方从而影响房价,反过来房价又会影响税收收入及开发商对土地的需求,进而影响社会民生。本文对我国东、中、西部地区住房价格和土地供给量、房地产税税赋之间的关系进行分析,探讨各地区的住房价格上涨原因。通过构建住房价格和土地供给量、房地产税税赋之间的PVAR模型,利用格兰杰因果检验、脉冲分析和方差分解方法来透视地方政府行为对住房价格的影响。分析结果显示,地方政府行为和房价之间存在着联动关系,但在推动住房价格上涨的原因上存在着区域差异：在东部地区,土地供应量影响房价;中部地区,二者联合推动了房价上涨。而在西部地区,房地产税税赋对房价的影响明显。在政策建议上,对地价推动房价的地区要从丰富住房来源和数量入手,而税赋影响房价的地区则要完善相关税制改革。     

Taming Airbnb: Toward guiding principles for local regulation of urban vacation rentals based on empirical results from five US cities

Urban vacation rentals, a phenomenon that has grown explosively very recently, bring benefits to cities but also impose quality of life and housing market impacts on neighborhoods. As a consequence, cities are beginning to grapple with creating regulatory regimes for managing this new land use and its encroachments on residential areas. This article uses webscraped data from Airbnb, the industry leader, to analyze the geographical patterns and concentrations of these impacts in five US cities: Austin, Boston, Chicago, San Francisco, and Washington, DC. It uses the findings to put forth four general principles for cities seeking to manage impacts imposed by Airbnb and its competitors. These are that webscraping is an imperfect but relatively cheap and effective means of gathering locally specific data; that “spiky” usage patterns dictate a microgeographic approach to regulation; that meaningful regulation necessitates dedicated enforcement, likely paid for with permit fees; and that it is desirable to distinguish between “mom-and-pop” hosts and those operating at a commercial scale.     

Social housing in France: A permanent and multifaceted challenge for public policies

This paper examines the dynamics of the overwhelmingly generous social housing in France that covers a wide spectrum of recipients. Being influenced by electoral power of rotating ruling parties and social ideals, policy formulations are often reflected by idealistic politics which tends to over-stretch the nation’s budget and restrict its scope in reaching its target groups. From the 1990s, fund availability has been further hit by economic globalization causing falling business profitability and high unemployment rates affecting notably ethnic minorities. Upcoming social crisis has been met with public response via a series of technical-led remedial acts to promote social integration in housing and by identifying social ills and polarization in sensitive and problematic urban quarters. New technical and financial measures in coping with the complexity and magnitude of social housing are expected to remain highly challenging in the French parliamentary politics.     

地方政府公共投资与区域经济增长的差异性分析

文章采用全国31个省、自治区和直辖市1995~2008年的面板数据,构建动态面板数据模型,考察了地方政府公共投资对区域经济增长的影响。研究表明,1995年以来我国地方政府公共投资总体上推动了区域经济增长,但不同公共投资项目的拉动效应在区域间存在着较大差异。     

论分权背景下的中国垂直管理体制——概况、评价及其完善建议

垂直管理是我国上下级管理体制中的一个重要现象。作为中央对地方、上级对下级进行调控的重要手段,这个现象在中国有不断被强化的趋势。文章认为,为规范垂直管理工作,一要合理划分上下级权限,调动两个积极性。二要设置合理的垂直管理体系,加强对垂直部门的管理。三要转变政府职能,实施科学的干部考评体系。四要推行扁平化治理,扩大下级、基层政府的自主权。     

以应对金融危机的视角看我国城市化进程中地方财政困境的化解

全球性金融危机使我国经济遭到严重打击,也给我国带来了巨大的就业压力。笔者以为,当前形势下扩大就业的根本出路在于加快我国的城市化进程,而这一目标的实现又离不开地方财政的支持,然而94分税制后我国地方财政困境已是不争的事实,当前的经济形势又进一步加剧了地方财政的危机,因此,研究如何化解地方财政困境问题已成当务之急。     

Stability and determinacy conditions for mixed-type functional differential equations

This paper analyzes the solution of linear mixed-type functional differential equations with either predetermined or non-predetermined variables. Conditions characterizing the existence and uniqueness of a solution are given and related to the local stability and determinacy properties of the steady state. In particular, it is shown that the relationship between the uniqueness of the solution and the stability of the steady-state is more subtle than the one that holds for ordinary differential equations, and gives rise to new dynamic configurations.     

Efficient local IV estimation of an empirical auction model

In this paper we examine semiparametric efficiency bounds and efficient estimators for the case of a linear local instrument variable (LIV) model under the assumptions studied in Abadie et al. (2002). We apply the semiparametrically efficient estimation method to analyze the relation between bid dispersion and early bidding in an online auction dataset, which is collected from a natural experiment conducted in Nekipelov (2007). The results confirm the theoretical findings developed in Nekipelov (2007). The semiparametric efficient estimation procedure substantially improves the statistical significance of the effect of jump bidding on bid dispersion.     

Integrating expected coverage and local reliability for emergency medical services location problems

Daskin's MEXCLP model [Daskin M. A maximum expected covering location model: formulation, properties, and heuristic solution. Transportation Science 1983;17:48-70] was one of the first efforts to capture the stochastic nature of emergency medical services (EMS) location problems within a mixed-integer formulation. With their subsequent introduction of MALP, ReVelle and Hogan [The maximum availability location problem. Transportation Science 1989;23:192-200] offered two key advances, local vehicle busyness estimates and the α-reliability objective. While these constructs have influenced many subsequent EMS location models, they have been subjected to relatively little empirical analysis. To address this, we introduce the LR-MEXCLP, a hybrid model combining the local busyness estimates of MALP with the maximum coverage objective of MEXCLP. We then solve a series of problems with all three models and employ simulation to estimate aggregate service levels. We find that LR-MEXCLP leads to modest but consistent service gains over both MALP and MEXCLP. These results support the merits of local busyness estimates, but they also suggest that the α-reliability objective may be inappropriate when seeking to maximize aggregate system response capabilities. More generally, our research underscores the utility of (a) linking modeling assumptions and goals with real-world application contexts, and (b) employing simulation or other techniques to validate theoretical results.     

Local cuisines and destination marketing: cases of three cities in Shandong,China

This study analyzes how the three cities of Jinan, Qingdao, and Qufu in Shandong Province of China use their cuisines in promoting their destinations. Based on a critical review of previous studies, a conceptual framework was developed, which included five closely related areas: foods, beverages, dining, farming, and food festivals. All related texts, images, videos, brochures, booklets, and websites designed to market these three cities were content-analyzed. The study findings suggest that all the three cities have not yet fully utilized their cuisines in their destination marketing efforts. Although some of their culinary resources appear in their marketing materials, the local cuisines of these three cities are not yet skillfully integrated into their marketing efforts. The present study offers specific theoretical and practical implications on marketing the culinary resources of destinations that are in the early stages of their development.
