Psychological Oil Price Barrier and Firm Returns

In this paper, we investigate the psychological barrier effect induced by the oil price on firm returns when the oil price reaches US$100 or more per barrel. We find evidence of the negative effect of the US$100 oil price barrier for: (a) the entire sample of 1559 firms listed on the American stock exchanges; (b) both foreign and domestic firms, with domestic firms significantly more affected; (c) the 10 different sizes of firms, with the smaller firms less affected compared to the larger firms; and (d) 17 sectors of firms, with firms in the utilities, mining, and administration sectors being the least affected.     

中国创意产品及创意相关产品的国际竞争力研究——基于RCA指数和TC指数的实证分析

根据联合国贸易和发展会议创意经济数据库2002-2010年的数据,分析了我国创意产品及创意相关产品的进出口额、国际市场份额及主要贸易伙伴,并对我国创意产品及创意相关产品的RCA指数和TC指数进行定量研究,发现我国创意产品及创意相关产品的国际贸易竞争力总体较强,但存在着出口市场过于集中、贸易结构较为单一和文化科技含量低、核心竞争力不足的缺陷,认为通过解放思想、创造宽容的文化氛围和创意环境,充分利用和开发我国丰富的历史文化资源、积极开展对外文化交流和不断开拓新的国际市场将有助于提高我国创意产业的发展以及创意产品和创意相关产品的国际竞争力.     

我国现行粮食价格政策面临的问题与对策研究

我国现行粮食价格政策面临许多问题,应借鉴主要发达国家与地区对粮食价格干预政策的经验,完善粮食最低收购价格与种粮直接补贴政策,增加种粮农民收入,推进粮食产区新农村建设。     

Determinants of residential water demand in Germany

We econometrically analyze the impact of several economic, environmental and social determinants for the per capita demand for water in about 600 water supply areas in Germany. Besides prices, income and household size, we consider the effects of population age, the share of wells, housing patterns, precipitation and temperature. We also explore why current per capita residential water consumption in the new federal states is about 30% lower than in the old federal states. Since average cost pricing may cause an endogeneity problem, we apply instrumental-variable procedures in addition to single equation ordinary least squares, but find no evidence that prices are endogenous. Our estimation results suggest that the price elasticity of water demand in Germany is around − 0.24. The income elasticity is positive, decreases with higher income levels and is at least three times higher in the new federal states than in the old federal states. Current differences in prices and income levels explain about one third of the gap in residential water use between the two regions. Household size and the share of wells have a negative impact on per capita water demand, and water use increases with age. Finally, the findings provide some evidence that rainfall patterns rather than total rainfall affect water consumption, while temperature appears to have no impact at all. All outcomes are robust to a log-log and two types of semi-log specifications for the water demand function.     

城投债对地区产能过剩的影响：促进还是抑制*

在构建城投债影响产能过剩的理论基础上,以我国2004-2016年地级市面板数据为样本,本文检验了城投债影响产能过剩的具体效应和相关机制。研究发现：城投债与地区产能过剩之间呈现U型关系;其中城投债对产能过剩的影响在中西部地区、南方地区、大城市和金融危机爆发后更为显著;机制检验表明,地方政府借助城投债压低工业用地价格和投资交通基础设施会加剧产能过剩,且压低工业用地价格带来的效应更为严重。因此,本文从适度控制债务规模、改善体制激励措施和完善要素定价机制等方面提出相应建议。     

城市地价空间自相关分析——以宿州市为例

运用全局和局域自相关统计量及地统计学半变异函数分析方法,对宿州市商业和住宅地价的全局自相关、各项异性及局域自相关特征进行了全面分析.结果表明:在2 800m范围内,宿州市商业和住宅地价均存在较强的正自相关性且趋于高值集聚,随着相关距离的增大,地价半方差按球状模型曲线增长,自相关性逐渐减弱;在不同方向上,地价的空间自相关特征不尽相同,南北方向上的空间自相关范围要大于东西方向,但随机性较强,自相关程度较东西方向弱;在全局呈显著自相关的情形下局域地价也主要呈空间集聚格局,但部分地区表现出异质性.     

上海外高桥保税区发展水平的集成综合评价研究

本文首先建立了上海外高桥保税区发展水平综合评价指标体系,然后针对不同综合评价方法得出的评价结果可能存在差异的现象,结合模糊综合评价和因子分析的特点,提出了一种把模糊综合评价和因子分析相结合的集成综合评价方法,并对上海外高桥保税区发展水平进行了横向和纵向集成综合评价。应用表明,该集成综合评价方法比单一方法更加全面和有效。     

Impact Fees and Real Estate Prices: Evidence from 35 Chinese Cities

Local governments often charge developers impact fees to finance local public goods. This has been practiced in Chinese cities for more than two decades; however, no empirical studies have tested the effect of impact fees on real estate prices. Using a panel data set for 35 large- and medium-sized cities from 1998 to 2008, we find that impact fees lead to a significant increase in real estate prices. For a given city, an increase in impact fees by one yuan leads to an increase of about 5 yuan in the price of newly-built housing; a 1% increase in impact fees leads to an increase of 5 percentage points in the housing price index and 7 percentage points in the land price index.     

货币政策为何及如何关注食品价格

食品价格是通货膨胀压力的灵敏反映指标,且由于食品部门供应价格弹性、存货缓冲能力、需求价格弹性和生产效率相对较低,产品同质化程度相对较高,食品价格的弹性明显高于非食品价格,加之在通货膨胀和经济周期过程中,食品部门具有需求顺周期和供给逆周期的特征,食品价格波动幅度往往远高于非食品价格,存在一定程度的超调。因此,文章建议货币政策应充分关注食品价格,同时适当提高对食品价格波幅的容忍程度。     

美国城市公园评价体系的内容、应用 及启示——以ParkScore指数为例

中国快速城镇化的过程伴随着各类城市绿地公园的 规划建设。对城市公园系统综合质量的科学评价关系着城市开 放空间品质的提升、居民生活质量的提高和公共服务设施规划 水平的进步。以ParkScore指数为例,对美国城市公园综合 评价系统的建设过程、评价标准和指标体系进行系统介绍和特 征评述,总结分析其在城市规划实践和研究中的应用,提出我 国应完善城市空间数据库建设、引入以人为本的评价指标和加 强指标体系建立过程的有效性等建议措施,旨在为我国城市公 园综合评价系统建设提供借鉴。
