Online product ratings offer consumers information about products. In this dissertation, I explore how the design of the rating system impacts consumers’ sharing behavior and how different players are affected by rating mechanisms. The first two chapters investigate how consumers choose to share their experiences of different attributes, how their preferences are reflected in numerical ratings and textual reviews, whether and how multi-dimensional rating systems affect consumer satisfaction through product ratings, and whether and how multi-dimensional rating systems affect the interplay between numerical ratings and textual reviews. The identification strategy of the observational study hinges on a natural experiment on TripAdvisor when the website reengineered its rating system from single-dimensional to multi-dimensional in January 2009. Rating data on the same set of restaurants from Yelp, were used to identify the causal effect using a difference-in-difference approach. Text mining skills were deployed to identify potential topics from textual reviews when consumers didn’t provide dimensional ratings in both SD and MD systems. Results show that ratings in a single-dimensional rating system have a downward trend and a higher dispersion, whereas ratings in a multi-dimensional rating system are significantly higher and convergent. Textual reviews in MDR are in greater width and depth than textual reviews in SDR. The third chapter tries to uncover how the introduction of monetary incentives would influence different players in the online e-commerce market in the short term and in the long run. These three studies together contribute to the understanding of rating system/mechanism designs and different players in the online market.

Description理性决策理论基于“完全理性”假定,追求帕累托最优即个体的利益最大化。但是实际决策过程中,人的行为具备“有意识的理性,但这种理性又是有限的”,投资者也是并不是完全理性、同质的。海外投资也是如此,其背景特征诸如地域、性格、年龄、财富等特征都会对海外投资决策产生重大的影响,其程度大小势必也会因投资者背景特征的差异有所不同。考虑到投资者风险偏好与海外投资活动的关系鲜有文献涉及,笔者愿意做“第一个吃螃蟹的人”,选取该视角展开论述。

本文首先对前人的研究进行总结,概述了风险偏好的理论和偏好水平的度量办法,并总结了风险偏好对海外投资影响的理论基础,即决策理论和有限理性与行为经济学理论,为本文的研究奠定了坚实的理论基础。

其次,开展了问卷调查,对小城市城镇人群、二三线大城市人群、一线大城市人群、海外华人群体等不同地域的25-60岁之间的人群作为调查对象,回收了有效问卷3748份,并就问卷结果进行了描述性分析。发现跨地域人群有着不同的投资需求,小城市城镇人群整体来说对于海外投资需求较低;二三线大城市人群对海外投资不抗拒且具备一定研究和分析能力;一线大城市人群26%已考虑移民或大量海外投资,对海外投资产品有很强的分析能力;海外华人群体38%已考虑移民或大量海外投资,对于各类海外投资产品的接触机会很多。

再次,本文对风险偏好水平进行综合评价和度量。在此基础上,设定了研究变量和研究模型,采用回归分析的方法,对跨地域人群风险偏好、跨地域人群风险偏好对海外投资影响两块进行了实证分析,并验证了相关假设。本文认为,跨地域人群具有较为明显的风险偏好,其中一线城市人群风险偏好最高,高于海外华人群体,高于二三线大城市人群和小城市城镇人群。基于教育水平、财富程度和信息获取的风险偏好对海外投资影响的实证分析结果显示,风险偏好越高的区域,海外投资总额越多。充分验证了跨地域人群不同的风险偏好,以及风险偏好对海外投资的显著正向影响关系。最后,本文针对实证结果提出了相应的对策建议。

Description近些年来,我国城市化进程不断加快,到2020年我国常住人口城镇化率将达到60%左右,户籍人口城镇化率将会达到45%左右。伴随着我国城市化进程的高速推进以及经济水平的不断提高,公共物品及服务的需求程度加大,政府单独出资建设公共项目会导致资金不足、经营管理效率低下等问题。与此同时,我国当前不同层级地方政府的政府性债务都达到了一个非常高的水平,截至2017年末,中国地方政府债务16.47万亿元,债务率(债务余额/综合财力)为76.5%,其中地方负有偿还责任的债务约12.9万亿,地方政府性债务的控制和转化成为经济新常态下重要特征之一。在地方债务压力较大的情况下,PPP将替代土地财政和地方政府融资,为我国新型城镇化建设提供可持续的资金支持,PPP模式成为当前城市建设领域融资的重要选项。

据此,本文基于实证研究方法探讨在债务约束的背景下,在地方政府债务约束下,PPP模式的引入,对城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量的影响;与此同时,考虑到地方政府的政策很大程度上受到是由地方官员,特别是受到作为地方政府党政“一把手”的市委书记和市长的晋升压力和激励的影响,讨论市委书记/市长的晋升压力和激励对PPP模式引入效果的影响。研究发现,在地方政府债务约束下,PPP模式的引入,显著增加城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量;同时,地方政府官员存在利用PPP放大城市建设和规划规模的行为,反映了PPP项目在引入和使用的过程中很大程度上受政府官员的激励的影响。

Description近年来,越来越多的工作团队将功能性领导角色分配给那些具有必要才能的成员。认识到这一趋势,领导学领域的学者开始将他们的关注重点从自上而下的垂直影响过程转移到团队成员之间的水平和共享的领导过程。共享领导,被定义为一种团队现象,即领导的角色和影响力在团队成员中分配,已经在一系列学术领域中得到了相当大的关注,包括工业和组织心理学、组织行为学、战略管理、和创业管理等。与其他领导理论关注正式任命的领导者的领导作用不同,共享领导强调团队成员在团队领导过程中的代理作用。特别是,越来越多的证据表明,共享领导在提高团队效率方面发挥着积极的作用。因此,共享领导力是一个有趣的新领域,它丰富了我们对领导力的理解,并将领导力范式从将领导力视为个人的属性转变为将领导力视为集体的属性。本文以AR公司的技术或研发团队为例,对其共享型领导的典型特征、表现形式以及对员工个体创造力和离职意向的影响机制进行了分析。第一,理清了技术型团队共享型领导的特征与表现形式。技术团队共享型领导主要实现了领导力与影响力在团队成员内部之间的共享和横向分担,且领导与下属之间的角色界限也变得模糊。同时,技术团队共享型领导表现在开放性的领导风格、团队内部的知识分享与共同学习以及领导角色定期轮换与交流等。第二,探讨技术型团队共享型领导对个体创造力与离职意向的影响机制。本文采用定量实证研究方法,按照量表开发、数据采集、数据分析等程序,检验共享型领导对个体创造力与离职意向的影响机制,研究发现:共享型领导能够正向影响员工的团队认同;员工的团队认同能够负向影响其离职意向;员工团队认同在共享型领导与员工离职意向之间具有中介作用;共享型领导与心理授权正相关;心理授权与个体创造力正相关;员工的心理授权在共享型领导与员工创造力之间有显著的中介作用;支持性人力资源实践在在共 享型领导与员工心理授权之间起到调节作用;支持性人力资源实践在在共享型领导与员工团队认同之间起到调节作用。

The advancement of information and communication technology (ICT) has significantly transformed how people communicate and obtain information in both their personal and professional lives. In the realm of digitally-facilitated social interaction, this dissertation calls for attention to the importance of information technology artifacts (IT artifacts) on social welfare by showcasing that the careful design and usage of IT artifacts have the potential to enhance the effectiveness, efficiency, and fairness of social interactions. The first study centers around addressing the cold-start issue that often arises when new products are introduced. Specifically, I investigate how machine-generated content can enhance the equity of new products. Analyzing data from Kaggle.com, my research demonstrates that the use of machine-generated content is effective in tackling the cold-start problem by increasing the adoption of the product in the initial phase. Additionally, my findings reveal that machine-generated content can also reduce information asymmetry for users regarding the datasets or associated providers. As a result, these outcomes provide strong evidence supporting the use of machine-generated content to enhance equity in online communities. The second research investigates the impact of a platform’s decision to impose application fees on enhancing the quality of matching results in an online labor market. Based on data obtained from Freelancer.com, my analysis demonstrates that the implementation of application costs serves as a motivator for workers to submit fewer but more selective bids. This, in turn, increases the likelihood of employers offering contracts, as workers are less likely to apply casually or without much thought. Overall, these results indicate that application costs can enhance the efficiency of the matching process. In the third study, I examine whether gender differences exist in telework adjustment as a response to disasters and to what extent such adjustments can help reduce gender inequality, using the COVID-19 pandemic as an example. The study's findings reveal the following: 1) Female workers exhibit a higher rate of telework adjustment than their male counterparts by 7% after accounting for differences in job sorting, and female workers are more responsive to external constraints. 2) Telework adjustment can help mitigate gender inequality in the labor market.

In recent years, the decentralized exchange (DEX) has shown an explosive growth trend in recent years. Uniswap, as one of the largest decentralized exchanges, invented Uniswap, a decentralized financial protocol of the same name based on exchanging cryptocurrencies. Automated transactions between cryptocurrency tokens on the Ethereum blockchain. Currency trading participants create a liquidity pool based on this agreement, and this paper mainly studies the factors that affect the liquidity of currency trading.Specifically, this paper explores the factors that affect monetary liquidity through three hypotheses. The first is the impact of rates on liquidity, exploring the differences in liquidity under various rates. Then, the impact of differences in Uniswap protocol versions on liquidity was studied. Compared with the V2 version, the Uniswap V3 version added centralized liquidity,which changed the unpaid loss. . This feature makes Uniswap V3 the most flexible and efficient protocol. Finally, the influence of different active users on liquidity is compared, and the change trend of liquidity under different numbers of users is explored. Based on the above three assumptions, this paper adopts GARCH and OLS regression analysis to explore and analyze the collected currency transaction data, and draws the following conclusions for the three assumptions: (1) Researcher may conclude that rates are correlated with trading volume, and volume growth impacts liquidity capacity and increases rates. Therefore, the fee rate has a significant impact on liquidity. (2) Compared with V2, V3, quantitative analysis was carried out using unpaid loss. It was found that impermanent loss has a more significant impact on the liquidity of the V3 version but has little correlation with the V2 version. (3) According to the analysis and comparison of the model, there is no obvious ARCH phenomenon among active users, so it is believed that there is no significant correlation between the two. (4) Combining conclusions 1 and 3, researcher further analyzed the impact of several independent variables on liquidity and found that the fee rate has a more significant influence than active users

Description2016年12月26日中国全面实施 “两票制”政策,“两票制”与“多票制”的不同就是药品销售发票的开具次数不同,“两票制”只能开两次发票,就是药品生产企业销售药品给医药流通企业可以开一次发票,医药流通企业销售药品给公立医疗机构可以再开一次发票,总共只能开两次发票。研究发现“两票制”对医药行业在股市层面和企业基本面层面的影响出现了背离现象;同时发现“两票制”对于上游企业的毛利率和销管费用率有正向影响,对于高市值企业的毛利率和二级行业集中度有正向影响,对国有控股企业的行业集中度有正向影响;对于总资产规模较小的企业的影响要大于规模较大企业;降低了患者的药费负担。 本文所研究的“发票”是指在中国境内购销商品,提供或者接受服务以及从事其他经营活动中,所开具和收取的收付款凭证。纳税人从事正常的生产经营活动,一方面要向收款方收取发票,同时也要向付款方开具发票。全国统一发票监制章的式样和发票版面印刷的要求,由国家税务总局规定,禁止私印、伪造、变造发票。
