共享经济可持续性评价：社会感知与客观绩效     

董晓松  霍依凡  赵星 《科研管理》2023,44(1):79-88

共享经济行业可持续性评价的社会感知和客观绩效不一致将造成认知错位、投资误判和政策失效等结果。本文在线挖掘2017—2019年我国主要社交媒体上29 771条文本信息，并收集行业统计数据，综合测度共享经济行业的可持续性并比较其差异。研究发现：社会公众并不认为共享经济行业具有显著的总体可持续性，而且行业实际绩效展现的可持续性与社会大众认知截然不同。进一步发现：受限于主观认知能力，社会公众认为共享经济可持续性主要来自可观察到的行业外部经济和外部生态等维度，但客观绩效表明共享经济行业内部的经济和外部的技术优势才是其可持续性的重要支撑。此外，二者评价的差异在住宿与医疗等产能共享内部过程不易被大众观察的行业中最为突出。  相似文献   

Protective behavior in ride-sharing through the lens of protection motivation theory and usage situation theory     

《International Journal of Information Management》2021

The frequent occurrence of security incidents in ride-sharing is a challenge for the survival of IT-enabled ride-sharing platforms. Passengers’ protective behavior is an effective means to alleviate this issue, with benefits to both the passengers and the platforms. This study explores the mechanisms of passengers’ protective behavior in the ride-sharing context by combining protection motivation theory (PMT) and usage situation theory. We test our hypotheses using data (n = 346) collected from a field survey based on a real scenario. The findings reveal that PMT and usage situation theory work well to explain passengers’ protective behavior during ride-sharing. This study explains the motivation behind passengers’ protective behavior in the ride-sharing context, extends the contents of PMT by exploring its antecedents, and extends the contents of usage situation theory by introducing a new dimension. Our findings can help ride-sharing platforms take appropriate strategies to improve passengers’ protective behavior.  相似文献   

重大体育赛事对城市经济发展的影响--基于中国70个大中城市面板数据分析     

毛丰付  郑芳  朱书琦 《上海体育学院学报》2020,(5):24-36

重大体育赛事的举办在一定程度上能推动承办城市转型发展,但也可能对当地经济产生某种不良影响,这主要源于对重大体育赛事与城市经济发展的内在规律和作用机制认识不够清晰。以2000-2017年22项具有全国影响力的重大体育赛事为基础,利用中国70个大中城市面板数据,采用双重差分法,分析重大体育赛事对城市经济发展的影响。发现:全样本数据下重大体育赛事的举办会促进城市第一产业向第二、第三产业发展;对比国内和国际赛事,重大体育赛事对第三产业的促进作用均显著高于第二产业;以1 085家上市公司数据为样本,采用事件研究法进行分析,发现不同行业利用重大体育赛事的窗口期存在显著差异。  相似文献   

建设体育强国背景下体育经济重要地位及其发展策略     

高〓峰 《广州体育学院学报》2019,(2):13-16

加快体育强国建设已成为一项国策，研究如何提高和建设可持续发展性的体育产业经济以解决人民日益增长的美好体育生活需要和不平衡不充分的发展之间的矛盾对建设体育强国具有重要意义。采用哲学辩证理论分析体育产业经济对体育强国构建的重要性，统计分析目前我国体育产业经济发展现状及其与发达国家的差距，结合十九大新时代背景下给出未来体育产业经济发展策略以期寻求为构建体育强国给出一些指导意见。认为：体育经济是体育强国的重要基石；开展全民健身运动、优化体育产业结构、政府政策导向市场化、跨产业融合增加与其他产业的结合度对构建体育强国具有重要的意义。  相似文献   

战略性新兴产业与经济发展耦合协调发展研究——基于安徽省的实证研究     

谢国根 《科技管理研究》2018,(22)

基于系统耦合理论,对安徽省战略性新兴产业系统与区域经济系统的耦合协调发展状况进行测度和系统评价。结果显示,安徽省大多数地级市的战略性新兴产业与区域经济并未实现同步型发展,但两者发展的一致性程度在逐渐提升;就两者耦合协调度而言,总体偏低,大多数地级市仍处在中低度耦合阶段,但在时间序列上呈现逐渐提升的态势,总体状况趋于良性发展;在空间格局上,耦合协调度一定程度上呈现以合肥、芜湖为中心逐渐向外围扩散的趋势,但中心城市对周边地区耦合协调程度提升的辐射和带动作用还有待进一步加强。  相似文献   

When information wanted to be free: Discursive bifurcation of information and the origins of Web 2.0     

Eran Fisher 《The Information Society》2018,34(1):40-48

In the 1990s the aphorism “information wants to be free” reigned supreme, limiting our thinking in consequential ways. In actuality this aphorism was a fragment of a much more nuanced statement by Steward Brand, who also talked about “information wants to be expensive.” It seemed for quite a while that there was no resolution to the contradiction: information as both free and expensive. Eventually Web 2.0 resolved this contradiction by providing an architecture where information could be both free and expensive. Web 2.0 was not a product of technological advances: social media, wikis, big data platforms, and so forth. It was borne out of the understanding that free information on media platforms could yield profitable data on users. This article lays bare the discursive moves through which this understanding came about.  相似文献   

Mobile banking use: A comparative study with Brazilian and U.S. participants     

《International Journal of Information Management》2019

As we can see in recent studies on mobile banking, there is an increasing number of papers addressing this new technology. Mobile banking contributes to the quality of life of people living in both developed countries, and also in emerging economies. In this context, we develop this paper in order to compare the determinants of mobile banking use between respondents from two countries with different levels of development: Brazil and the United States. Our theoretical model includes six variables as determinant factors of mobile banking use. In order to analyze path coefficients and test the six hypotheses, we employed a structural equation model. We also employed a quantitative test (multi-group analysis) to analyze the difference of path coefficients between the models of the two countries. The main results indicate similarities among the perceptions of the respondents that participated in the survey, but differences in coefficient magnitude.  相似文献

韩国莹  李战江 《科技管理研究》2018,(13)

通过将绿色经济评价指标体系的五个不同方面作为约束条件引入模型,可客观、有效地得出影响各评价对象绿色经济发展状况的关键因子。主要做法:一是利用离差最大化优化模型对各评价指标赋权,保证所求权重的客观性与合理性。二是将5个不同层面分别作为制约条件引入评价模型得到模型最优解。三是分别对有、无制约条件下的各评价对象的排名波动情况进行分析比较,确定各盟市绿色经济的发展差异以及影响其发展优劣的关键要素。实证结果表明,环境保护的相关方面对各盟市绿色经济发展影响最大,资源承载力及人的全面发展方面次之。  相似文献   

CC-Qual: A holistic scale to assess customer perceptions of service quality of collaborative consumption services     

《International Journal of Information Management》2019

The paper defines and validates a scale—CC-Qual—to assess the quality of services provided through a Collaborative Consumption (CC) model.The authors have borrowed a set of items arranged in eight dimensions from the literature on CC. A panel of selected practitioners (seven CEOs of CC companies) assisted in the design of the questionnaire, which was launched in June 2018. A sample of 127 questionnaires was used for exploratory factor analysis. A second sample of 301 users was used for confirmatory analysis using EQS 6.4 software.A scale of 21 items gathered under five dimensions is proposed. Accordingly, the perceived quality in CC is composed of five dimensions: three of them related to the interaction with the platform (“site organization”, “platform responsiveness and agility” and “legal protection and trustworthiness”), another related to the perceived quality of the peer service supplier (“peer service provider”) and the last one to assess the encounters with other consumers and with the person who provides the service (“social interaction”).This study provides a useful measure for the assessment of the perceived quality of CC services, regardless of the activity sector. This instrument might assist managers for both assessing and benchmarking. The instrument also provides independent and reliable information for customers.  相似文献
