跳出地产看地产——试论滨海新区房地产的宏观走势

滨海新区的开发开放正式纳入国家战略已有一年,在此前后,滨海新区的房地产开发热已持续近两年.静观这两年的事态变化,开发者已由最初的喧嚣、癫狂而趋于理性,置业者和投资者浮躁的功利心态也逐步冷却.显然,坊间追捧和媒体热炒的房地产开发"盛世"并未如期而至;一些先行者创造的个案营销神话,似乎也未再现,惟一的奇迹,就是滨海的房价一再拉高,已经与中心城区比肩.滨海新区的房地产到底出现了什么问题?原因何在?需要有一个客观的诊断和解答.     

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study, a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions. Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and urban thermal conditions.

制度变迁背景下的社区权力与秩序——基于广州市一个城中村的研究

渐进的市场化和突发的制度变迁导致了城中村的权力格局和社区秩序发生了种种变化,居委会—村公司构成的权力结构及其互动关系目前已经成为城中村特有的"双轨制"权力模式,本文以广州市J社区为例深入分析这种双轨制的内在机制,认为社区内存在两种基于资源依赖基础上的循环链,由此带来了社区秩序的双重规则。     

Bayesian t-tests for correlations and partial correlations

In this paper, we develop Bayes factor based testing procedures for the presence of a correlation or a partial correlation. The proposed Bayesian tests are obtained by restricting the class of the alternative hypotheses to maximize the probability of rejecting the null hypothesis when the Bayes factor is larger than a specified threshold. It turns out that they depend simply on the frequentist t-statistics with the associated critical values and can thus be easily calculated by using a spreadsheet in Excel and in fact by just adding one more step after one has performed the frequentist correlation tests. In addition, they are able to yield an identical decision with the frequentist paradigm, provided that the evidence threshold of the Bayesian tests is determined by the significance level of the frequentist paradigm. We illustrate the performance of the proposed procedures through simulated and real-data examples.

完善我国个人所得税制的思考

个人所得税是调节国家与个人利益分配关系的重要杠杆,随着我国经济的快速发展、居民收入水平的大幅提高,个人所得税将是一项最有前途、最有发展潜力的税种。但我国个人所得税政策不尽人意,执行起来既失公平,又欠效率。文章分析了我国个人所得税制存在的问题,提出了相应的对策。     

工伤保险赔偿责任研究 ——以劳务派遣用工为切入点

劳务派遣作为一种灵活的用工形式,受到我国各类用人单位的青睐和广泛运用。2013年《劳动合同法》修订弥补了我国劳务派遣制度上的不足,但由于起步时间较晚,加上制度的复杂性,存在工伤赔偿制度的责任划分不清晰、工伤保险待遇先行支付具体操作存在困难、异地劳务派遣工伤保险制度执行不明确等方面的问题。我国需要从确立《劳动合同法》中派遣单位与用工单位的具体责任分担制度、完善劳务派遣工伤待遇先行支付规定、明确异地保险制度相关规定等方面入手,进一步完善工伤保险制度在劳务派遣用工中的适用,有效保护被派遣劳动者的合法权益。     

工会推进产业工人队伍建设的探索研究

产业工人是工人阶级的主体,在国民经济发展建设中发挥支撑作用。工会作为代表广大工人阶级利益的群众组织,在推进产业工人队伍建设改革中肩负着不可推卸的责任和重担。在目前新形势和时代变革下,我国产业工人队伍建设的现状还不能很好地适应经济转型中出现的新情况和新问题。对工会推进产业工人队伍建设的情况进行研究,在借鉴制造业强国经验的基础上,从思想政治引领、搭建发展平台、打造能力提升工程、利用“互联网+”和完善保障体系五个方面进行探索建设,从而为工会组织持续打造高素质产业工人队伍工作提供政策借鉴。     

中国老年人储蓄对家庭消费的影响 ——基于CHARLS面板数据的分析

在我国快速老龄化和居民储蓄率居高不下的背景下,结合老年人储蓄偏好和消费特点,构建家庭消费计量分析模型,文章利用CHARLS2011、2013、2015年微观跟踪调查数据,采用工具变量—随机效应模型划分年龄层次和消费类别逐级估计,重点考察老年人储蓄对其家庭消费的影响。研究表明,老年人储蓄水平越高,对家庭消费的促进能力就越强;分城乡来看,农村老年人储蓄对家庭消费的贡献更大;按年龄组别来看,中、低龄老年人储蓄对家庭消费的影响显著,高龄老年人储蓄对家庭消费的影响不显著;按消费类别看,老年人储蓄偏重于家庭基本生活、教育文化、健康等刚性消费支出,城镇和农村老年人储蓄对不同消费类别影响的差异主要表现在日常支出、医疗保健和耐用消费品等方面。此外,研究还发现,老年人拥有房产对家庭消费具有非常明显的提振作用,家庭收入和老年人借贷对家庭消费的贡献显著。
