Exploring subcultural differences in hofstede's value survey: The case of the Chinese

Hofstede's Value Survey Module (VSM) identifies fundamental differences in the way people in various countries perceive and interpret their worlds. After adjusting value scores on the basis of demographic features of samples in the present study, values between subcultural groupings in four Chinese-populated regions (Taiwan, Beijing, Hong Kong, and Wuhan) were compared, and strong subcultural differences revealed. A methodology is proposed to facilitate VSM comparisons using limited, secondary data sources. Propositions concerning subcultural differences are suggested on the basis of the findings.

Do farmers or governments make better land conservation choices? Evidence from China's Sloping Land Conversion Program

In developing countries with small holdings, targeting payments-for-environmental-services prices to site-specific environmental benefits becomes administratively impractical. Instead, governments fix price and either dictate parcel enrollment or let farmers decide, which might be expected to maximize environmental benefits and minimize opportunity costs, respectively. No paper has actually tested such hypotheses in a developing-country setting. This paper examines China's Sloping Land Conversion Program, with 32 million planting forests, using a unique dataset on 3397 parcels, including farmer-choice and government-choice parcels. Farmers consider similar criteria to local governments but weight land characteristics within the farm (not the landscape) and household characteristics.     

城市景观生态建设的研究

退社行为对合作社可持续发展的影响分析——来自渤海湾优势区211户退社果农的实证

基于目前合作社中存在的农户退社现象,本文利用211个有效样本实证分析了果农退社行为与果农合作社可持续发展的关系。研究发现:其一,从整体看,果农退社的四种方式均会对果农合作社可持续发展产生显著的负向影响,且负向影响程度由大到小依次为被迫退社、盲从退社、主动退社、隐形退社。其二,从细分维度看,一方面,主动退社、被迫退社和盲从退社会对合作社内部凝聚力、成员积极性产生负向影响,而隐形退社则对这二者无影响;另一方面,四种退社方式均会对合作社组织声誉、政府资源利用产生负向影响。其三,从发展水平看,果农退社方式对高水平果农合作社的可持续发展的负向影响程度相对轻微,且主动退社行为对高水平果农合作社的可持续发展具有显著的正向影响。其四,从比较分析看,果农退社方式对中、低发展水平合作社具有不同程度、不同方向的影响。本文研究结论对合作社管理者采取差异化措施防止退社现象蔓延、优化退社制度安排以及有效利用政府资源具有一定的启发。     

Persistence in Portuguese mutual fund performance

Recent evidence suggests that future performance is predictable from past performance, that is, funds with superior (inferior) performance in the past are likely to remain good (bad) performers in the future. This research addresses the persistence of mutual fund performance in a European regional market (the Portuguese equity fund market). Some of the problems in evaluating fund persistence are identified in the context of limited sample size and using the peer group median as a benchmark for contingency table analysis of performance persistence. The criteria for assessing performance persistence based on the contingency table methodology of repeated winners and losers are presented in terms of significance statistics, adjusted for small sample bias. The adjustments are accomplished through the Yates continuity correction and Fisher's exact p-value. The appropriateness of each criteria under different circumstances is also discussed. The analysis of the returns of all Portuguese domestic equity funds, since a representative number was established, shows some performance persistence (on a quarterly basis). The persistence, however, is reduced when the returns are controlled for the various dimensions of risk. Significant risk persistence has been documented. Furthermore, for more or less frequent intervals of measurement, the industry persistence is rejected, although individual funds exhibit superior/inferior performance.     

石油、石化企业综合利用煤、油、气资源途径初探

近年来我国原油进口数量急剧增加。石油安全问题引起广泛关注。而我国煤炭与天然气资源相对比较丰富。统筹规划并合理利用煤、油、气资源，通过煤化工、石油炼制、石油化工3个行业技术上的互相借鉴，资源上的互相替代，产业链的互相补充，尽量减少石油的消耗，以减轻对进口原油的依赖。     

中国资本账户开放程度的测算

对我国资本账户开放程度的准确判断是相关理论研究和决策分析的基本前提。从名义和实际两个方面对中国的资本账户开放程度进行测度的结果表明:(1)当前我国的名义资本管制处于中等水平,而实际资本账户的开放水平要远高于名义资本账户开放水平;(2)在存在较大套利空间的情况下,即便存在较为严格的资本管制,资本管制的有效性也很难长期维持;(3)虽然资本管制程度的加强很难对实际的套利资本流动加以控制,但在资本管制措施逐渐放松以后,却很容易导致实际资本流动性的急剧提高,这一点,造成了我国当前资本管制政策的"两难"选择。     

我国经济增长与大气污染物排放的关系——基于分省面板数据的经验研究

本文应用1998-2004年期间我国30个省(市、自治区)的面板数据,通过综合简化型模型,研究了3种大气污染物和经济增长之间的关系.实证研究发现在3种大气污染物与经济增长之间不存在倒U型环境库兹涅茨曲线.二氧化硫排放与经济增长之间呈倒N型曲线,与多数研究结果不相符;同时,第二产业比重、经济增长速度、单位GDP能耗和环境政策强度四个解释变量总体上对3个大气污染物的排放具有显著影响,并包含明确的政策含义.     

税收影响下的创业投资组合规模的决策模型研究

为分散投资风险,创业投资家通常为多个创业企业提供资金和管理支持,从而形成创业投资组合。限于精力,创业投资家必然面临着投资组合规模和管理支持二者间的平衡。税收政策影响着创业投资家对于创业企业权益份额的获取,因而影响着其对创业企业的管理支持力度,进而影响其投资组合规模。
