资本渐进开放下我国与国际利率的联动分析——基于中国和美国的比较

一般来说,利率在国家间的传导主要有两条渠道:国际贸易间的传导和资本自由流动下的利率平价机制。本文采取分阶段考察,通过建立计量经济学模型,利用单位根检验和协整分析加以验证,发现在资本项目部分开放后,中美利率开始具有联动效应,作用方式又具有自身的特点。目前资本项目开放度不够高是阻碍我国同世界利率联动的主要原因。     

基于DEA的绿色经济增长核算:以中国地区工业为例

本文构建基于DEA的绿色经济增长核算模型,将考虑非期望产出的劳动生产率变化分解为技术效率变化、技术进步和资本深化。中国地区工业的经验分析表明,与发展水平无关且省际差异大的技术无效率普遍存在;各省工业增长的首要源泉是资本深化,其次是技术进步主导的全要素生产率进步;各省工业劳动生产率增长差异主要源于资本深化差异,其次是技术效率变化差异主导的全要素生产率进步差异;如不考虑非期望产出,会低估资本深化对经济增长的贡献,高估技术进步的贡献,而技术效率变化的贡献可能被高估、低估或无影响。     

剥离环境因素的中国高技术产业创新效率综合测度研究

由于未剔除环境因素和随机误差的影响,运用传统数据包络分析（DEA）和随机前沿分析（SFA）对高技术产业创新效率进行研究,容易引起评价结果误差。采用二者相结合的三阶段DEA模型对高技术产业创新效率及其影响因素进行测度与分析,能够保证评价结果的有效性。研究结果显示：规模效率不足是限制我国高技术产业创新效率提升的关键因素;另外,市场开放度能够显著正向促进高技术产业创新效率提升,而政府资助、地区经济发展和地区竞争不利于创新效率提升。最后,对投入要素与技术效率进行聚类分析,将我国内地28个省市划分为4种创新类型,并〖JP〗提出提升高技术产业创新效率的政策建议。     

大学生创业能力结构的理论分析与实证检验

大学生创业能力研究对建设创业型经济、完善高校教育体系和促进人的全面自由发展具有重要意义。通过理论与文献梳理,结合个案访谈结果,将大学生创业能力划分为机会发掘能力、组织管理能力、战略决策能力、资源整合能力、创新创造能力和挫折承受能力6个维度。根据因子内涵定义和相关学者研究成果,设计了大学生创业能力测量量表,并对江苏省高校进行了实证数据采集,验证了大学生创业能力结构的信度和效度。

An assessment of organic apparel,environmental beliefs and consumer preferences via fashion innovativeness

The topic of organic apparel has been widely discussed among academics and practitioners in recent years. While numerous studies have been done on the topic, few studies to date have assessed the topic of fashion innovativeness and its influence on attitudes towards organic apparel. In addition, an evaluation of consumer preferences for organic apparel from a conjoint analysis perspective has not been implemented. Thus, the purpose of the present study was to identify which organic apparel attributes are most important to high fashion innovativeness and low fashion innovativeness groups. Furthermore, the variables of environmental beliefs and attitudes towards purchasing organic apparel were assessed. An online survey was developed to measure the variables, including a full profile discrete choice design used to measure attribute preferences for t‐shirts. The data were analyzed using a multinomial logit model and desirability indices. The results indicated that the low fashion innovativeness group preferred organic and eco‐friendly apparel more than the high fashion innovativeness group. In addition, when examining high fashion innovativeness and low fashion innovativeness groups overall, the preferred t‐shirt was Dri‐Fit, Cotton Jersey Knit, Made In America, Eco‐Friendly and $25.00. However, when examining high fashion innovativeness and low fashion innovativeness groups separately for the preferred t‐shirt, differences appeared in Sustainable. The results suggest that high fashion innovativeness and low fashion innovativeness groups may desire different organic apparel attributes when considering organic apparel.     

Low carbon transport strategy in Europe: A critical review

ABSTRACT

The purposes of this article are to depict ongoing trends regarding the transport system in Europe, to introduce readers to the challenges that Europe (and the rest of the world) will face in the future, to show which strategies Europe plans to deploy to mitigate the negative impacts the transport system imposes on the overall system, and finally to discuss the potential of these suggested strategies to contribute to the objectives of the European Union in the long run.     

Understanding Japanese tourists’ shopping preferences using the Decision Tree Analysis method

This study was designed to assess the factors affecting Japanese tourists’ shopping preference and intention to revisit Korea. The analytical method applied in this study was Decision Tree Analysis, which is under-utilized in tourism studies. A total of 300 questionnaires were collected on the basis of on-site survey method and used for data analysis. Among interesting findings, three groups including ‘respondents who were satisfied, accompanied, and spent US$50–300 on shopping’, ‘respondents who were satisfied, accompanied, and had a shopping expenditure of US$300–1000’ and ‘respondents who were satisfied, accompanied, and had a shopping expenditure of US$1000–5000,’ showed a high level of intention to return to Korea for the purpose of shopping. In addition, two groups ‘those who were interested in shopping in Korea, preferred a shopping mall as a shopping destination, and had an educational level of below high school’ and ‘those who were interested in shopping in Korea, preferred a shopping mall as a shopping destination, and had an educational level of a college graduate or above’ showed a higher level interest in merchandise than in shopping venue attractiveness.     

城镇居民教育收益率的地区差异及其解释

利用中国社会科学院经济研究所"中国城乡居民收入分配"课题组1995年和2002年的家庭抽样调查数据,本文使用分层线性模型重新估计了1995年、2002年我国居民的教育收益率,得到了不同于OLS估计的结果:(1)我国城镇居民教育收益率的地区差异很大,差异主要来源于省内各城市之间,来源于省间的差别并不显著;(2)计算了省内城市劳动力市场化程度对当地教育收益率的边际影响,发现劳动力市场的发育确实有利于提高教育收益率,而且劳动力市场化程度的差异在一定程度上为各地教育收益率的差异提供了解释。
