宅基地流转不宜受限制

农村集体土地作为市场经济的重要生产要素,由于受现行法律制度的约束,尚没有完全发挥出应有的作用,尤其是农村宅基地转让还“犹抱琵琶半遮面”,不能登上市场交易的“大雅之堂”,从一定程度上制约了农村经济的发展。目前,《物权法(草案)》经全国人大常委会公布征求意见。按三审稿规定:“宅基地使用权人经本集体同意,可以将建造的住房转让本集体内符合宅基地使用权分配条件的农户;住房转让时,宅基地使用权一并转让。禁止城镇居民在农村购买宅基地。”笔者认为,物权立法不宜再对宅基地流转进行限制。限制宅基地流转的利弊为什么限制宅基地转让?…

城乡分割与我国农村养老保障建设的困境

改革开放以来,我国进入社会转型加速时期,在农村,传统的家庭保障与土地保障已不适合农村经济社会的发展的需要.因而建立农村养老保障制度刻不容缓.但是整体而言我国农村经济社会条件相对落后,当前建立现代意义的农村社会养老保障制度不够现实.造成此困境的主要原因是长期的城乡分割政策,而要走出此困境,必须创造城乡整合的社会经济条件,以促进农村传统养老保障模式向现代社会养老保障模式转型.     

U.S. House Prices over the Last 30 Years: Bubbles,Regime Shifts and Market (In)Efficiency

This paper studies U.S. house prices across 45 metropolitan areas from 1980 to 2012. It applies a version of the Gordon dividend discount model for long‐run “fundamentals” and uses Mean Group and Pooled Mean Group estimation to estimate long‐run and short‐run determinants of house prices. We find great similarity across cities in that the long‐run house prices are largely explained by the same fundamentals; the long‐run rent to price ratio is approximately 5% plus 0.75 times the real interest rate (which is on the order of 2%). However, adjustments to deviations from the fundamentals are slow, in the long‐run, closing the gap at a rate of around 10% per year. We find sharp differences in short‐run adjustments (momentum) away from the fundamentals across cities, and the differences are correlated with local supply elasticities (more momentum with lower elasticity). Analysis of residuals suggests strong cyclical deviations, which are mean‐reverting.     

Short Sales and Price Discovery in the Hong Kong Real Estate Market

Indirect real estate (IRE) returns are often shown to lead direct real estate (DRE) returns. Apart from differences in liquidity, transaction costs, and management skills, the DRE market is also less complete than the IRE market—when negative shocks arrive, one can only short IRE (e.g., real estate stocks or REITs), but not DRE. This study investigates if short sales in the IRE market convey any information to the DRE market. Based on high‐frequency (weekly) property price data in Hong Kong from 2000 to 2012, we find that short sales in the IRE market led DRE returns, even after controlling for the lagged IRE returns in a VAR model. This supports an information spillover mechanism in which the DRE market learns private information that is not reflected in IRE returns. The spillover effect, however, weakened after the recent global financial crisis because the increased uncertainty over the credibility of individual firms made short sales more reflective of firm‐specific information than real estate market fundamentals.     

广东生猪生产坝状与发展对策研究

广东是全国最大的猪肉消费大省,也是生猪生产大省。广东生猪生产的规模化程度和生产效率都发展迅速,但也存在在生猪数量安全、猪肉质量安全和环境压力等问题。本文通过对广东生猪生产现状、所存在的问题的分析,针对性地给出了发展广东生猪产业的相关建议。     

口服液中粗多糖提取方法的改进

为了考察改进苯酚-硫酸法测定保健品口服液中粗多糖提取方法的可行性,以某保健品口服液为样品,对采用苯酚-硫酸法测定粗多糖含量时的多糖的不同提取条件与测定进行一个较为详细、系统的研究。结果表明:样品经改进提取条件后测定,试验结果表明有良好的线性关系,精密度RSD值为0.69%,稳定性良好,平均加标回收率为101.0%。该方法改进后提高了该实验的精密度和准确度,重现性高,并使结果更加可靠和稳定。     

城乡一体化进程中乡村土地利用效益评价

文章在实地(河北省邢台市)调研基础上,通过文献分析与成本分析相结合的方法对城乡一体化进程当中乡村土地利用效益进行系统的评价,并在此基础上揭示出目前我国在城乡一体化进程当中乡村土地利用过程当中存在的问题,并给予相应的建议。研究结果表明:我国城乡一体化进程当中,对我国乡村土地利用效益影响较大的主要因素有政府政策不合理、对于土地利用效益缺乏足够认识,这些原因直接导致在城乡一体化进程当中乡村土地耕地边际化现象严重、城市建设用地规模过大、土地生态效益低下及乡村土地配置不合理等现象的出现。基于对土地效益评价与我国目前乡村土地利用状况的深入分析,该文认为应从土地的经济效益、社会效益及生态效益对于目前城乡一体化进程当中存在的土地利用效益偏低的现象进行整改,例如提高土地的集约度,实行大规模的机械化生产进而提高土地的经济效益;通过合理规划商业用地、居民住房用地及农业用地的比例提高土地的社会效益;发展多种形式的生态养殖与特色旅游业促进土地生态效益的提高。     

略论二元经济的实质与转化——基于信息和知识视角

二元经济是发展中国家在发展过程中最基本的经济特征.从信息和知识的角度看,任何经济系统、组织、个人都是信息和知识生产、收集、传递及利用的装置,二元经济形成的关键在于不同区域在信息和知识的生产、收集、传递及利用能力及效率上的差异.因此,二元经济如何发展和转换完全取决于该区域内与信息和知识利用相关能力的形成和发展.     

Environmental Governance of Enterprises and their Economic Upshot through Corporate Reputation and Customer Satisfaction

Drawing on resource‐advantage and signalling theories, we investigate two mechanisms, namely corporate reputation and customer satisfaction, by which the environmental governance of enterprises can benefit their economic performance. Based on secondary data from the 500 largest US enterprises compiled from multiple sources, our findings contribute to the literature by establishing the link between corporate reputation and green reputation. We also establish the economic performance paths of environmental governance via corporate reputation and customer satisfaction. This study expounds on why ‘green’ matters and identifies the performance roles of two corporate strategic resources extractable from the environmental governance of enterprises.
