中国城市科技人才集聚促进了全要素生产率增长吗——来自285个地级市的经验研究

基于2005—2018年中国内地285个地级市数据，对城市科技人才集聚与全要素生产率（简称“TFP”）进行测度分析，实证考察科技人才集聚对TFP的影响。结果表明：①城市科技人才集聚与TFP空间分异特征显著，但二者具有较强的时空一致性，即科技人才集聚特征显著的城市，其TFP也相对稳定；②城市科技人才集聚对TFP的影响呈倒U型，但研究期内大多数城市仍处于集聚效应占主导阶段,科技人才集聚通过提升城市技术进步水平促进TFP增长，而科技人才集聚对技术效率的影响呈倒U型；③不同类型城市科技人才集聚对其TFP影响的异质性显著，且适宜集聚区间也存在差异。省会城市及一、二线城市等优势特征显著的城市所能承受的科技人才集聚规模上限更高，有利于通过释放集聚红利促进TFP增长，而非省会城市、三线及以下城市等则拐点值较低。     

Mitigating panic buying behavior in the epidemic: An evolutionary game perspective

The panic buying behavior under public health emergencies will lead to many adverse consequences, such as material waste, price fluctuation and uneven distribution of epidemic prevention materials, which will pose a threat to the social stability and economic development. In this paper, we construct a tripartite game model to explore the strategic choices of the public, merchants and the government in order to effectively respond to the panic buying behavior in the epidemic. The results demonstrate that: (1) Eight evolutionary stable strategies emerge in the panic buying events. The worst scenario can be improved by adjusting some relevant parameters. (2) The probability of the public choosing the strategy of “not involving in panic buying” depends on the potential benefits and losses of snapping up, rather than the extent of price rising. (3) The probability of merchants choosing the strategy of “not bid up price” depends on the intangible benefits. (4) The probability of the government choosing the strategy of “active supervision” depends on the supervision costs and government credibility, rather than the amount of fines. In addition, strategic suggestions to mitigate panic buying behavior are put forward from the perspective of each stakeholder.     

Does justice affect brand advocacy? Online brand advocacy behaviors as a response to hotel customers’ justice perceptions

This study focuses on customers' information-sharing behavior in the context of online brand advocacy behavior regarding hotel brands. We aim to explain hotel customers' online brand advocacy behavior through three-sided justice evaluations (i.e., justice for employees, justice for the self, and global belief in a just world), and their hotel satisfaction. Hypotheses are tested by using survey data acquired from 688 individuals on Amazon's Mechanical Turk (MTurk) through partial least squares structural equation modeling (PLS-SEM). The findings show that customers' perceptions of justice for the self positively affect their hotel satisfaction, perceptions of justice for employees and the global belief in a just world positively affect online brand advocacy behavior, and hotel satisfaction also positively affects online brand advocacy behavior. We expand current research efforts on online brand advocacy research and provide theoretical and managerial implications for the development of marketing and management research and practice.     

Future perspectives on the role of extended producer responsibility within a circular economy: A Delphi study using the case of the Netherlands

Extended producer responsibility (EPR) is a proposed policy approach to promoting the circular economy (CE) within the European Union. This research used a policy Delphi to explore perspectives on improving EPR policies to further contribute to the CE goals of the Netherlands. Both the potential improvement and critical reflections discussed by CE and EPR experts and practitioners from this study contribute to a more detailed understanding of the future governance of CE practices. We present various activities to improve EPR and insights from Delphi participants that emerged from the study. This paper shows that whilst actors agree, in essence, that there is a need for modifying EPR, what the specific changes to the form are and to whom the new responsibilities apply is contested.     

瞪羚企业认定是否提高了企业创新质量

瞪羚企业认定是我国创新驱动发展战略的重要措施，旨在培育高科技、高成长性企业，促进科技进步和经济高质量发展。为研究瞪羚企业认定能否切实提升企业创新质量，利用2005-2018年新三板企业数据和PSM-DID方法研究瞪羚企业认定对企业创新质量的影响及作用机制。结果发现：①瞪羚企业认定对企业创新质量有正向促进效应，且这种效应在地区和企业层面均存在异质性；②人力投入是瞪羚企业认定发挥作用的重要渠道；③制度因素对瞪羚企业认定影响的调节效应有限，意味着我国市场化改革和知识产权保护工作仍需进一步完善。最后，为政府有效开展瞪羚企业认定工作、促进企业提高创新质量提出政策建议。     

西北生态山岳旅游健康发展评估

生态山岳的旅游健康发展程度对山地旅游资源的可持续利用具有重要的影响。采用层次分析法和熵权法对2018年西北地区的华山、麦积山和天山天池的旅游生态健康进行了分析。结果表明:三大山岳景区旅游健康发展均处于健康状态;在资源健康方面,天山天池表现为非常健康,华山和麦积山处于健康等级;在环境健康方面,麦积山处于非常健康,华山和天山天池处于健康等级;在经济健康和旅游社会方面,三大景区均表现为健康。     

代际传承对家族企业创新投入的影响

基于社会情感财富理论，以2009-2015年394家中国A股上市家族企业为有效研究样本，就代际传承对家族企业创新投入的影响进行实证研究，考察组织环境特征变量--环境不确定性与家族企业治理主体个体特征变量--二代继承人受教育程度对该影响的调节作用。研究发现：①代际传承会降低家族企业创新投入水平；②环境不确定性会强化代际传承对家族企业创新投入的负向影响；③二代继承人受教育程度会减弱代际传承对家族企业创新投入的负向影响。由此提出，家族企业应将延伸型社会情感财富纳入战略决策考量，并切实加大创新投入，重视对二代继承人多维能力的考察与培养；政府应着力为家族企业代际传承与创新战略实施创造良好的金融、法制与经营等制度环境，提供智力资本与企业家网络平台等支持。     

产学研协同创新成本分摊机制研究

产学研协同创新是推动技术创新的一条重要路径，但创新成本分摊机制是影响产学研协同合作的一个重要问题。通过构建充分竞争市场下的多阶段博弈模型，从成本分摊机制角度探究了如何有效推进产学研协同创新。通过模型扩展与求解，获得成本分摊后的帕累托改善以及产学研协同创新的可行路径。结果表明：企业和学研方基于自身收益最大化而进行的成本分摊协商无法实现帕累托最优，而轮流出价博弈模型下的成本分摊形成机制能够有效改善各方收益，并使整体收益达到帕累托最优，因此是一条现实可行的帕累托改善路径，其中，各方获得的收益增量与耐心程度的对比有关。     

A comparative study of eight COVID-19 protective measures and their impact on Swiss tourists’ travel intentions

A comparative vignette-based experimental survey design incorporating various socio-psychological factors, linked to the Theory of Planned Behavior (TPB), the Health Belief Model (HBM) and the Domain-Specific Risk-Taking scale (DOSPERT) was carried out to test variations in eight travel-related COVID-19 protective measures on Swiss tourists’ travel intentions. Among the tested measures, vaccination passports, surgical masks and quarantining are those that stand out the most, with surgical masks having the greatest acceptance and willingness to adopt while traveling. Quarantining, on the other hand, appears to have a deterrent influence on travel intentions, and vaccination passports have the lowest perceived barriers during travel, but the highest perceived benefits in mitigating the spread of the infection. The discussion of individual differences has specific implications for tourism management against the background of our empirical findings.     

Internal conflict and Bank liquidity creation: Evidence from the belt and Road initiative

The Belt and Road Initiative is the most important international economic strategy in the 21st Century initiated by China. In this paper, we conduct the first international study on the effects of the host country’s internal conflict risk of the Belt and Road Initiative on bank liquidity creation, one of the key functions banks provide for the public. We find that the host country’s internal conflict risk negatively affects bank liquidity creation. The results are also economically significant and robust to subsample tests. It also indicates that Chinese firms that will conduct foreign investments in the countries of the Belt and Road Initiative should take the host country’s internal conflict risk into account.
