我国特大城市交通战略的未来走向——京沪城市交通比较与启示

交通政策实践分析表明,京沪两市目前交通实践主要集中于交通供给政策,交通需求政策和空间政策实施力度不够,这与发达国家大城市交通实践形成鲜明对比,也导致了京沪城市交通效率低下.两市交通政策的最大差别在于对个体机动车辆的控制方面,上海通过私家车牌照拍卖,在一定程度上控制了小汽车的增长速度,而北京由于缺乏有效举措导致小汽车过快增长,这一政策差别是两市交通效率差异的主要原因.通过京沪交通比较研究,就我国特大城市交通战略的未来走向提出相应的政策建议,以期为城市交通发展决策提供参考依据.     

Retrospective questions: data quality,task difficulty,and the use of a checklist

Data from a national panel study with waves in 1987 and 1991 (N=1257), present evidence of the low accuracy of responses to retrospective questions, concerning both attitudes and behaviour. Applying a split ballot design, it is investigated whether using a checklist improves the response accuracy for a retrospective question about one single event: how respondents (N=363) did obtain the job they had four years ago. Furthermore interaction effects of ‘task difficulty’ are examined. The response accuracy indeed increases by using a checklist; however, this increase is not statistically significant. The expected increase of the checklist effect with higher ‘task difficulty’ appears for longer recall intervals, but not for more frequent changes of jobs. It turned out that for male respondents all the predicted effects are indeed clearly present. But for female respondents the checklist appeared to have no effect, irrespective of the task difficulty. A tentative explanation for this unexpected gender effect is suggested by pointing at indications that the male and female respondents differed in the way they obtained their job.     

建设项目选址的规划论证

区域重大建设项目选址涉及到区域社会、经济、环境等各个方面,其选址的合理与否关系到区域社会经济的持续、快速、健康发展.科学的分析论证可加强建设项目的可操作性,也可使其规划管理依据更加充分、决策更加科学合理.基于此认识,提出了建设项目选址符合城市规划论证的主要内容,并以330千伏西安西南郊变电站选址为例进行了详细的说明和论述.     

中国住宅投资引领经济增长吗?

本文运用1985—2009年中国各省、直辖市、自治区的数据,对住宅投资与经济增长之间的领先—滞后关系进行分析。结果表明,无论是1985—2009年全时段还是以1998年大规模房改为分界线的分时段,无论是全国各省市还是分区域的各省市面板数据,经济增长引领住宅投资的单向Granger因果关系是稳定的;不同于一些研究和政策措施所主张的住宅投资引领经济增长的观点,本文认为找不到证据来支持住宅投资带动经济增长的论点。由此可见,所谓"住宅引领增长假说"在我国并不成立,而我国自上世纪90年代中期以来一直大力促进住宅投资以带动经济增长、把住宅建设当作国民经济的新增长点和支柱产业的政策值得反思。     

中国资本外逃与外国直接投资关系的实证分析(1984-1999)

该文分别采用相关分析、因子分析和因果分析三种计量分析方法,分析了中国资本外逃与外国直接投资之间的关系.该文的研究表明,中国资本外逃与外国直接投资之间存在着显著性很强的正相关关系,并且因子分析与因果分析的结果也支持这一结论,说明驱动中国资本外逃的主要因素不是投资环境恶化,中国资本外逃在很大程度上是由于对内资和外资采取的差别政策待遇所引起的,并据此提出了相应的政策启示.     

Recovering Hicksian Consumer Surplus within a Collective Model: Hausman's Method for the Household

The purpose of this paper is to describe the implications of the collective model of household behavior for the methods used to estimate the economic value of non-marketed environmental resources. After demonstrating how the separability restrictions inherent in the collective model allow individual preference and household income allocation choices to be distinguished, the paper demonstrates how the framework can be used to recover Hicksian consumer surplus. An algebraic example is used to illustrate how the framework can be used in valuing environmental resources.     

从“其他绿地”到“区域绿地”： 城市非建设用地下的绿地规划转型 与优化

新版《城市绿地分类标准》(CJJ/T 85—2017)以“区域绿地”代替“其他绿地”，这为城市非建设用地下绿地的保护利用提出了新的要求和目标。解读新标准指导下城市非建设用地中的绿地建设发展要求并进行科学合理的规划，是响应当前城市绿色发展新形势和满足人民日益增长的美好生活新需求所面临的重要课题之一。聚焦从“其他绿地”到“区域绿地”的分类调整，分析新标准下区域绿地的内涵和特征。以河北省承德市为例，结合城乡发展需求，阐述区域绿地规划的核心转型思路。并从目标、内容、方法和评价等方面，论述区域绿地设定下城市非建设用地中绿地规划的具体内容和方向。最后从空间政策、发展引导、部门合作和大众参与等方面，提出了规划实施保障优化的策略。以“区域绿地”的解读为源，聚焦当前城市建设用地内外绿地规划建设割裂的现状问题，提出区域绿地规划的转型优化措施和实践经验，以期为新时代中国城市绿色空间的拓展与优化提供参考。     

Banks’ non-traditional activities under regulatory changes: impact on risk,performance and capital adequacy

Using the big six Canadian chartered banks quarterly financial statements and daily stock market data from 1982 to 2018, we examine the impact of non-interest income on Canadian banks’ risk, performance and capital under the different major regulatory changes made to the Bank Act of Canada. Our results show that Canadian banks’ expansion into non-traditional activities had slightly decreased their risks and significantly improved their performance benefitting from income diversification. Moreover, while adhering to capital adequacy regulation, reshuffling banks’ portfolio towards non-traditional activities did not reduce Canadian banks’ capital ratio. In spite of the re-regulation towards universal banking against ring-fencing, this feature buttresses the effectiveness of capital adequacy regulation in Canada in linking banks capital allocation with their risk taking.     

迁移理论的基础:“理解人口学”的分析框架

根据学者布如金所提出的人口理论研究新范式,在对其进行概括和拓展的基础上,提出了“理解人口学”的分析框架。同时综合部分迁移研究的成果,融合不同研究方法,从四个层次:迁移行为的概念假设、迁移行为的发端、迁移行为的外部环境和迁移行为的时间纬度,为人口迁移行为分析提供了-个跨学科的研究视野。
