基于朴素贝叶斯模型的电子证照用证智能推荐

数字政务是数字政府建设中的重要组成部分,研究电子证照智能服务有助于数字政务改革。结合朴素贝叶斯模型与某省政务数据构建用证预测模型,并对模型的有效性进行检验。结果表明：法人类型高频办件前10种组合占全部组合的49.46%,远高于个人类型政务服务事件;全省范围内个人用证、法人用证推荐准确率分别可达到53.22%、68.51%,按地市构建模型能够有效提升准确率,部分区域准确率最高可达96.24%;缩小判定政务服务事件先后关系时间窗口,推荐准确率明显降低。研究结果表明了研究方法的有效性,有关方法和结论对提升政府效能具有支撑参考作用。     

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.     

Overcoming the barriers to successful implementation of information technology in the U.K. hotel industry

This article examines the organisational barriers to successful implementation of information technology in the hotel industry. These are barriers of will, ability, and finance which block the routes to integration of internal systems.     

Empirical study on Chinese tourists’ perceived trust and intention to use biometric technology

This paper presents a theoretical model based on the Technology Acceptance Model combined with a perceived trust model. SPSS 23 and Amos 22 were used to analyze Chinese tourists’ responses regarding use of biometric technology in hotels and to assess whether their perception of trust – measured through five potential factors – affected their intention to use it. Chinese tourists traveling in Macau were recruited, and three types of biological identification technology were discussed. A total of 600 questionnaires were sent out, and 583 effective questionnaires were recovered. The results that in addition to perceived ease of use, other factors affected visitors’ perceptions of trust. The degrees of effectiveness, however, differed between the three biological identification technologies. Fingerprint technology was revealed to be the most trusted and accepted biometric technology.     

Online Customer Experience and Its Relationship to Repurchase Intention: An Empirical Case of Online Travel Agencies in China

The study reported here examines the relationship between flow experience and repurchase intention by focusing on the joint mediating effects of loyalty. Data were taken from a survey of shopping experiences, at online travel websites, of 325 customers in China. The results show that flow experience has a significant effect on repurchase attention. Moreover, interactive speed, skill, challenge, perceived control, telepresence, perceived usefulness, and perceived ease of use are positively related to flow experience. Lastly, the findings show that loyalty, to some extent, acts as a mediator between flow experience and repurchase attention.     

德国CO2捕获和封存技术发展展望

减低温室气体排放,防止气候变化已是全球共同面临的巨大挑战和急迫解决的问题。世界上有约40％的CO2排放源于燃烧化石燃料的发电厂。目前,全球公认的降低CO2排放最有效的方法之一是碳捕获和封存技术（CCS）。CCS是指CO2从工业或相关能源的排放源分离出来,输送到一个封存地点,并且长期与大气隔绝的一个过程。CCS是稳定大气温室气体浓度的减缓行动中的一种选择方案,具有减少整体减缓成本以及增加实现温室气体减排灵活性的潜力,是有效大量去除CO2排放的关键技术。本文介绍了CO2捕获封存技术的基本情况和德国对CCS技术开发和应用制定的相关资助计划、发展规划和实施项目,并对我国CCS技术的发展提出建议。     

食品安全监管长效机制建构研究

近年来食品安全问题时有发生,食品安全已经成为关系国计民生的一个极为突出的社会问题。因此,加强食品安全监管的研究,建立和完善我国食品安全监督管理体系,实施有效的食品安全应对措施,具有极其重要的意义。本文分析了我国食品安全监管存在的问题,并在借鉴国际经验的基础上,提出几点政策建议：健全食品安全检验检测体系;加强食品安全教育体系建设;充分发挥消费者组织、行业协会的监督作用等。

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。     

FDI技术溢出对我国创新能力影响的分析

随着经济全球化的发展,国家间的经济竞争日益激烈,自主创新能力越来越被认定为一国竞争力的主要标志。文章利用1991-2012年中国技术创新方面的数据,建立计量模型,研究了FDI对我国创新能力的影响。结果表明,我国自主RD投入是提高创新能力的最重要因素,而外商直接投资在整体上对我国研发和创新能力无非常明显的溢出效应。我国必须努力促进FDI的技术溢出效应,同时注重培育内资企业的自主创新能力。
