Analyzing air cargo flows of international routes: an empirical study of Taiwan Taoyuan International Airport

Air cargo demand is an important aspect of the operation and planning of private and public agencies responsible for airports. While most existing studies in this field include only geo-economic characteristics of airports and their hinterlands as explanatory variables, this study develops a gravity model of air cargo flows by trying to incorporate more factors that might influence international air cargo flows of an airport. The model is developed based on the panel data of air cargo services on scheduled routes at Taiwan Taoyuan International Airport during the years 2004-2007. The results indicate that population, air freight rate and three dummy variables, including the regional economic bloc of the “Chinese Circle”(an informal partnership between Hong Kong, Macao, Taiwan and mainland China), the Open Sky Agreements and long established colonial links, are key determinants of international air cargo flows from/to Taiwan. These results suggest a wider array of factors needs to be considered in policy.     

“十一五”期间全国地质资料管理与服务情况分析

通过对2006-2010年全国地质资料管理情况通报分析研究,“十一五”期间,全国各级国土资源管理部门和馆藏机构开展了大量工作,全面履行依法汇交和转送工作,地质资料汇交量和馆藏量持续增长,基础设施进一步改善,全国地质资料网络服务能力日趋增强,日常服务数量持续增加,抗旱救灾应急服务成效显著。     

What determines international tourist arrivals in India?

Using data for 18 major tourist originating countries to India from 2001 to 2015, this study examines the major determinants of international tourist arrivals in India. The results indicate that past experiences of the tourists, per capita income in the tourist originating country, relative costs of living between India and the country of origin, and the level of infrastructure development in India are key determinants of international tourist arrivals in India. Furthermore, both transportation and communication infrastructure are important in attracting tourists to India. In particular, evidence suggests that availability of road and air network and telephone connections has favourable impacts on international tourist arrivals in India. These results are robust to the inclusion of additional variables. These results have important policy implications.     

中国工业行业能源强度影响因素的实证分析

利用中国31个工业行业1998—2004年面板数据,采用分层聚类方法,按年平均能源强度将31个工业行业分为高能源强度行业和低能源强度行业,并对全工业行业、高能源强度行业和低能源强度行业能源强度的影响因素进行了实证分析。研究结果表明,能源价格上涨对提高工业行业的能源利用效率有显著的促进作用;FDI进入程度的增大提高了工业行业尤其是高能源强度行业的能源强度;进、出口商品结构变化对工业行业能源强度没有显著影响;工业内部的行业结构变化对全工业行业和低能源强度行业的能源强度有显著负的影响,对高能源强度行业没有显著影响;R&D投资强度的增加提高了工业行业特别是高能源强度行业的能源强度。     

长三角地区影响FDI流入因素的实证研究

本文以邓宁的区位优势理论为基础,选择劳动力工资水平、市场容量、基础设施、产业结构、制度变迁和进出口商品总值等关键变量,利用江苏省、上海市和浙江省的面板数据对这些变量与FDI的流入量之间的关系进行了实证分析,并简要推断了FDI的类型,得出了具有一定解释力的结论。     

Targeting Conservation Investments in Heterogeneous Landscapes: A Distance-Function Approach and Application to Watershed Management

To achieve an environmental objective at least cost, decision makers must integrate information about spatially variable biophysical and economic conditions. Although the biophysical attributes that contribute to an environmental outcome are often known, the way in which these attributes interact to produce the outcome is often unknown. We introduce a nonparametric conservation targeting approach that relies on distance functions to cost-efficiently allocate conservation funds. We apply the approach empirically to the case of conservation contracting for water-quality objectives. The contract portfolios derived from the application have many desirable properties, including intuitive appeal and robust performance across plausible parametric scoring measures.     

中国金融产业集聚与地区工业化——基于2002年—2010年省际面板数据的分析

金融产业集聚在地区工业化进程中发挥着非常重要的作用。通过区位商法的分析发现,我国东、中、西部地区金融产业的集聚程度有着较大差距,其中东部地区集聚度较高,而中西部地区则集聚度较低。面板数据的计量检验结果表明,金融产业空间集聚的差异对我国三大不同地区工业化产生了不同影响。总体而言,银行业集聚对工业化的影响作用最大,而证券和保险业集聚作用则较小,而对于不同地区、不同省份以及不同时期来说,这一作用也存在着差异。因此,可以通过调整金融业的空间集聚格局来促进工业化的发展。     

福建省高端装备制造业技术创新效率评价

将技术创新分为两个阶段——投入转化阶段和转化产出阶段,运用DEA两阶段法和DEAMalmquist指数法,对2008—2012年福建省高端装备制造业5个细分行业的两阶段技术创新效率进行了静态和动态评价。研究结果如下:在技术创新的第一阶段,福建省高端装备制造业的投入转化效率在很大程度上依赖于技术进步,但这种趋势在减弱;在技术创新的第二阶段,福建省高端装备制造业的转化产出效率呈下降趋势,且技术进步和技术效率对之共同发挥影响作用。     

宽松的环境政策能吸引更多的外商直接投资吗——基于中国工业省级面板数据的分析

利用我国1997~2009年的工业省级面板数据和动态面板GMM估计方法,考察了相对宽松的环境政策是否是吸引FDI的主要原因。研究发现,环境政策较宽松的地区能够吸引更多的外资流入,但这种影响并不大,所以,以降低环境标准、牺牲环境为代价来吸引FDI不是明智之举;与东、中部地区相比,西部在吸引FDI上处于明显劣势,这在一定程度上加剧了我国经济结构的失衡。     

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.
