民营资本的进入对我国风电产业发展的影响——基于断点回归的分析

为克服单差法存在变量内生性,倍差法对于控制组的严格要求往往无法得到满足,故文中采用断点回归的分析方法,在无对照组的情形下,对我国风电产业2012~2015年的资产总计、主营业务收入以及发明专利数月度数据进行实证研究,探究民营资本的进入对我国风电产业的影响。实证结果表明,从短期看,民营资本的进入对我国风电产业规模与技术效率具有统计上的显著正面作用,具有一定的经济意义;另外,这一机制的推行对产业创新产生了显著的负面作用。     

碳信息披露与企业投资效率-基于 2011~2015 年 CDP 中国报告的实证研究

本文以 2011~2015 年参与国际 CDP 项目的中国公司为研究对象,从投资效率视角探析碳信息披露与企业投资效率之间的关系,并就产权性质、管理层权力对二者关系的影响进行检验。结果发现：在其他条件相同的情况下,碳信息披露能够显著提高企业投资效率;同时,相较于非国有企业,国有企业碳信息披露更能提高企业投资效率;管理层权力越大,越会削弱碳信息披露对投资效率的改善作用。进一步研究发现,碳信息披露通过缓解投资不足和抑制过度投资的共同作用来提高企业投资效率,且这种作用在国有企业及管理层权力较低的企业中更为显著。     

A fuzzy comprehensive evaluation algorithm for analyzing electronic word-of-mouth

This study evaluates tourism experiences shared through electronic word-of-mouth (eWOM) across four Chinese attractions. The objective is to develop a framework for evaluating eWOM by constructing an indicator system and implementing an analytic hierarchy process with the use of a fuzzy comprehensive evaluation algorithm. This framework is achieved by mapping more than 6000 websites related to Chinese tourism attractions and filtering over 200,000 useful reviews to measure service performance. Results indicate that ecological–biological attractions failed to make tourists feel “very satisfied” in various aspects, such as overall evaluation, infrastructure, traffic, natural environment, and social environment. Overall, the study contributes by presenting a framework that can be adopted by tourism researchers and industry practitioners to understand tourist preferences and evaluate service performance to improve service quality.     

Using a network data envelopment analysis model to assess the efficiency and effectiveness of cultural tourism promotion in Taiwan

The importance of tourism promotion has been discussed throughout past studies, and the consequences of ineffective promotion have also been investigated. While tourism promotion is a topic of interest to many researchers, performance measurement used to assess the effectiveness of tourism promotion is a topic seldom discussed. The purpose of this study is to develop an approach based on the data envelopment analysis (DEA) model to evaluate performance for tourism promotion. The main difference compared with previous DEA models is the evaluation of multiple efficiencies in a single DEA implementation, and the assessment of overall efficiency in a ratio index. In the assumption of variables, we use cultural tourism promotion as a foundation in formulating the empirical evaluation, and we test the proposed model by using data across 20 regions in Taiwan.     

A stochastic cost efficiency analysis of international tourist hotels in Taiwan

The one-stage stochastic frontier approach (SFA) is used in this study to simultaneously estimate cost efficiency scores and factors of cost inefficiency for 66 international tourist hotels in Taiwan during 1997–2006. An SFA model with three outputs and three inputs is defined. The three outputs are room revenue, food and beverage revenue, and other operation revenue while the three inputs are price of labor, price of other operation, and price of food and beverage. This model also takes into account five environmental variables, including dummy variable of the hotels located in non-metropolitan area, dummy variable of chain hotels, the number of tourist guides, the minimum distance from each hotel to Taoyuan international airport and the minimum distance from each hotel to Kaohsiung international airport. Empirical results show that international tourist hotels in Taiwan are on average operating at 91.15% cost efficiency. All nominal variables are transformed into real variables in 1997 prices by GDP deflators. Chain systems, tourist guides, and international transportation can significantly improve the cost efficiency of international tourist hotels in Taiwan.     

中国省域森林公园技术效率测算与分析

文章借助数据包络分析方法（DEA）,利用2003～2008年的数据,对我国森林公园发展的效率进行研究,为我国森林公园旅游资源的优化配置和运行效率的提高提供参考依据,并测算了31个省区的技术效率、纯技术效率和规模效率,比较了它们之间的差异。结果显示,从全国来看,森林公园的技术效率较高;从个体来看,不同省区森林公园的技术效率存在较大的差异,上海、浙江、广西、广东等省区的技术效率较高;宁夏、内蒙古、安徽等省区的技术效率较低。通过优化投入规模与结构、人员培训等措施能够在一定程度上提高我国森林公园整体的技术效率。     

基于员工维度的旅行社业绩评价体系研究

业绩评价是旅行社进行科学管理的重要手段。智力密集型、服务型和相关型的旅行社行业属性,使员工人力资本体现出能动性及与内外部高度合作协调性的特征,成为旅行社竞争能力的核心资本。缺乏员工维度的业绩评价就会在一定程度上导致员工流失率上升和行业中＂柠檬市场＂现象的出现。文章从旅行社业绩形成动因的逻辑分析入手,构建了以员工满意度和员工服务效率结果指标为核心的旅行社业绩评价体系,并以此为基础从成本指标、时间指标及质量指标等过程指标角度进行了具体细化衡量。

中国城市节能评价的实证研究

首先,在评析我国现行节能考评指标局限性的基础上,界定了城市节能评价范围。其次,研究建立了包括工业、建筑业、城市交通、生活消费四个领域、三个层次、27个指标的城市节能评价指标体系,并构建了评价模型。第三,按照一定标准将城市用能水平划分为四个等级,并通过计算工业耗能指数A1和建筑、交通、生活综合耗能指数B,构建了城市耗能级别的判定准则Z=f(A1,B)。最后,以某城市为例进行了实证研究。研究结果表明:该城市2005年实际能耗位于第Ⅲ级,属于先进用能型城市;其中工业节能效果较好,建筑、交通、生活等其他三个领域节能有待加强。基本反映了该城市的能耗实际情况。
