Do Credible Firms Perform Better in Emerging Markets? Evidence from China

Prior research suggests that corporate credibility is associated with firm financial performance in developed countries. This article examines whether corporate credibility is related to firm performance using Economic Observer’s rating of corporate credibility in China, the largest emerging market in the world. Based on a four-stage valuation model, we find that more reputable and credible firms outperform those with low ratings by almost 20% in 3-year stock returns and have better 3-year net profit margins, return on equity, and sales growth. This study is the first to directly examine the relationship between corporate credibility and firm performance in emerging markets such as China, and our results confirm that firms with high credibility exhibit better financial and market performance at least in the following 3 years.     

基于HFA3824用于DSSS的PN序列的研究

住房抵押贷款可以分为传统的“不脱离资产平衡表”型(on-balance-sheet)和新型的“脱离资产平衡表”型(off-balance-sheet)或称之为美国风格的住房抵押贷款两种类型.资产经营融资是住房抵押贷款市场的创新发展,目前已成为一个宽泛的概念,包括了一系列的金融技术. 一般认为是指个别的缺乏流动性的资产和现金流,经过重新安排,由第三者在资产现金流的基础上提供融资,用于描述一系列广泛的商业、管理、会计目标的融资结构.

GATT1994文化贸易产品待遇条款评析

GATT1994第4条是WTO规则体系中唯一一条直接涉及文化产品贸易待遇的条款,其对于文化产品特殊性的认定,国内配额措施背离于多边贸易规则之禁止数量限制原则并在特定条件下例外于WTO体制基石之国民待遇的允许,经历了长久的争论与谈判,体现了文化贸易在多边贸易体系中的独特地位。然而GATT1994第4条的内容却遇到了科学技术的巨大挑战,在文化多样性作为全球公认价值的今天,其适用范围的大小也成为文化价值诉求能否顺利实现过程中的重要问题。     

To reallocate or not: Reconsidering the dilemma in China's agricultural land tenure policy

In China, rural land is collectively owned at the village level. Village officials usually have the power to reallocate land property across families on an ongoing basis due to demographic changes in the village. Realizing that frequent land reallocation and abusive land requisition will undermine economic productivity as well as social stability, the “Rural Land Contract Law” passed in 2002 explicitly reads that farmland tenure security must be maintained for at least 30 years since the last nationwide reallocation in 1998. The frequency and magnitude of land reallocation in Chinese villages have decreased as a result. However, failure to allocate land to the newly increased population often induced conflicts among village members if the security of land tenure for 30 years was strictly implemented. Administrative land reallocations then still continued in some villages to accommodate demographic changes in these places. Based on an almost nationally representative rural dataset collected in 119 villages of 6 provinces across China in 2008, this paper lays out some stylized facts about the administrative land reallocation after 1998. By analyzing the opinions of over 2200 farmers on the central policy of maintaining farmland tenure security, we are able to rationalize why some farmers support the policy while others oppose it. This analysis helps us to better understand the dilemma between efficiency and equity embedded in the current agricultural land system in China. It is further shown that social conflicts among village members may easily arise either due to administrative land reallocation or due to lack of it. We argue that this dilemma cannot be resolved effectively without coordinated reforms in household registration system which can help hundreds of millions of Chinese rural migrant workers to permanently settle in cities and release their farmland to those who stay in the countryside.     

宁波市旅游产业发展与生态文明城市建设耦合协调关系测度

基于生态文明城市、旅游产业的内涵及其作用机理,构建宁波市旅游产业与生态文明城市系统的评价指标体系,借助均方差决策法和综合评价法测度其综合得分,并引入耦合协调度模型对其旅游产业发展与生态文明城市建设的协调关系进行定量分析。结果表明:(1)2006—2015年宁波市两子系统的综合发展水平整体呈上升趋势,耦合度C徘徊在0.415 5~0.5之间,一直处于拮抗阶段;(2)两系统的耦合协调度D从2006年的0.315 2上升到2015年的0.661 6,呈现出由轻度失调、濒临失调到勉强协调、初级协调不断优化的趋势;(3)旅游产业与生态文明城市建设的耦合协调发展表现为两阶段,即2006—2010年属旅游产业发展滞后型和2011—2015年属生态文明城市建设滞后型。据此建议构建绿色旅游产业体系,全面提高生态文明城市管理水平,建设美丽宁波,着力打造天蓝山青水美的旅游环境。     

新疆畜牧养殖经济效益与碳排放脱钩关系的实证研究

党的十八大提出"把推动发展的立足点转到提高质量和效益上来"。新疆作为我国五大牧区之一,研究畜牧养殖业发展质量效益,对第一产业的健康可持续发展有重要的现实意义。畜牧养殖经济效益与碳排放动态关系的研究作为检验畜牧养殖业发展质量效益的前提和重点。因此,笔者根据1997年以来新疆畜牧业增加值作为衡量经济效益指标,根据9类反刍动物肠道发酵和粪便排放所产生的温室气体作为衡量碳排放指标,并利用Tapio脱钩模型,探讨新疆畜牧养殖经济效益与碳排放的脱钩情况,并对其脱钩状态进行分析。结果表明:(1)新疆畜牧养殖碳排放量由1997年的649.71万t增加到2014年的747.33万t,增幅15.03%,年均增长0.83%,呈现"持续上升-快速下降-缓慢上升"3阶段特征。碳排放量和碳排放结构空间差异明显;(2)新疆畜牧养殖经济效益与碳排放呈现"弱脱钩平稳-扩张负脱钩与强负脱钩交替-强脱钩转型"的演进关系,以弱脱钩、强脱钩为主。据此,提出相应建议。
