政府投资工程总承包项目设计优化认定与收益归属研究

工程总承包模式以设计与施工的高度融合,日益在建筑业受到青睐。但由于政府投资项目中存在有关结余资金上缴国库等规定,容易导致政府投资工程总承包项目下设计优化产生的成果是进行分成或作为结余资金上缴界定不清。鉴于此,本文通过政策文件,并结合政府投资项目特点,分析政府投资工程总承包项目设计优化的情形认定以及在不同结算依据和合同计价方式下设计优化收益归属的界定,为有效激励总承包单位积极进行设计优化奠定基础。     

Extending variety seeking to multi-sided platforms: Impact of new retailer listing

This study uses theories of variety seeking to examine how a new retailer listing on a multi-sided platform (MSP) affects consumer buying behavior. Using a unique dataset from an online MSP, we evaluate changes in purchase frequency with individual retailers after a new one is listed. Contrary to expectations, the results indicate that consumers increase their purchase frequency at existing retailers. Moreover, compared to consistency seekers, variety-seeking consumers show a higher positive effect as they buy even more. This result is observed for retailers in both competing and non-competing product categories. Finally, we discuss the theoretical contributions and implications for MSPs and retailers.

The new wave of AI-powered luxury brands online shopping experience: The role of digital multisensory cues and customers’ engagement

Academic literature retains a dearth of empirical evidence of the cutting-edge aspect of artificial intelligence (AI)-powered digital assistance and digital multisensory cues, despite the prospect of these factors on real-life customers' luxury brand online shopping experience. Thus, the aim of this study is to examine the significant pathway and effects of AI-powered digital assistance toward customers’ luxury brand online shopping experience. Drawing on S–O-R (Stimulus, organism, and response) and TRAM (Technology Readiness and Acceptance Model) paradigm, a multi-method research design was deployed to investigate constructs. Firstly, semi-structured interviews were utilized to explore customers' online behavior under the luxury brands and information technology aspect. Secondly, survey data were collected and analyzed by using partial least squares structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA). The PLS-based analysis of quantitative data confirmed the exploratory insights of qualitative findings, establishing the connections of AI-powered digital assistance, customer engagement, and customers' luxury brand online shopping experience. Research findings also suggest that customer engagement plays a mediation role in the relationship between AI-powered digital assistance and customers' luxury brand online shopping experience. Besides, digital multisensory cues moderate the relationship between AI-powered digital assistance and customer engagement. Further, fsQCA complements the findings of PLS-SEM that reveal the significant combination of factors that lead to the perceptions of customers' luxury brand online shopping experience.

我国民营企业转型升级的政府作用研究——基于政府行为视角的实证分析

将政府行为细化为政府效能、监管质量、法律规则和腐败控制四个变量,并对民营企业转型升级的相关指标进行量化处理,建立了衡量我国民营企业转型升级的综合指标,对政府行为对民营企业转型升级的影响进行了量化分析,得出以下结论：政府效能、监管质量和法律规则是影响民营企业转型升级的重要影响因素;政府效能与民营企业转型升级呈现正相关关系,政府效能越高,越有利于民营企业转型升级;监管质量对民营企业转型升级的影响较为显著,监管质量越高,越有助于民营企业转型升级;法律法规对于民营企业转型升级具有重要的影响作用,法律法规的执行力度越大,越有利于民营企业的转型升级;腐败控制与民营企业转型升级尽管也呈现一定的正相关关系,但并不很显著,这表明腐败控制的效果并没有直接反映为促进民营企业转型升级的重要因素.     

The Political Economy of Fiscal Supervision and Budget Deficits: Evidence from Germany

In many federal countries, local governments run large deficits, even when fiscal supervision by state authorities is tight. I investigate the extent to which party alignment of governments and fiscal supervisors influences budget deficits. The data set includes 427 German local governments for the period 2000–2004. I exploit a period after a far‐reaching institutional reform that entirely re‐distributed political powers on both the government level and the fiscal supervisor level. The results do not show that party alignments of governments and supervisors (co‐partisanship) drive short‐term deficits. Instead, I find that the ideology of partisan governments and supervisors matters: left‐wing local governments run higher deficits than their right‐wing counterparts; left‐wing supervisors tolerate higher deficits than right‐wing supervisors. These findings imply that political independence for fiscal supervisors is recommended.     

创新创业平台知识产权服务模式研究

2015年12月,国务院发布了《关于新形势下加快知识产权强国建设的若干意见》,正式提出“知识产权强国”战略。在 “大众创业,万众创新”大背景下,国家知识产权局等印发《关于进一步加强知识产权运用和保护助力创新创业的意见》。创新创业平台作为创新创业最重要载体,其知识产权服务尤为重要。借鉴亨利·埃茨科威滋的国家创新体系三螺旋模型[1],构建平台—入驻企业—知识产权服务机构的知识产权服务模式三螺旋结构。在问卷调查和实地调研等实证基础上,总结了3种创新创业平台的知识产权服务模式,即平台自行服务模式、外部服务模式、组合服务模式,并对模式进行了比较。同时,发现模式存在以下问题：政策重视程度不高、政策介入程度不够、前期评估工作不严谨、投资风险不共担、服务链条各环节分离等,并提出相关对策建议。     

Local Government Debt,Factor Misallocation and Regional Economic Performance in China

This paper examines total factor efficiency and productivity performance by taking into account local government debt (LGD) in 31 Chinese provincial regions for the period 2000–2013. The results show that neglecting LGD may overstate economic performance in Chinese provinces. The eastern region shows better performance in single factor efficiency and total factor efficiency than the non‐eastern regions. The western region shows the worst total factor performance. The north‐eastern region is the only region that has experienced a decline in total factor performance. The state‐dominated, investment‐driven development model may help technological progress across Chinese regions but could lead to significant factor misallocation. We argue that biases towards more state‐dominated investment and land supply in less productive western, central and north‐eastern regions, at the expense of investment and land supply in more productive eastern regions, have contributed to the recent slowdown in economic growth in China. Therefore, further market‐oriented reforms in factor markets should be considered in the future.     

科技云影响下的科技服务平台运行模式研究

科技云是改变科技服务平台多头分散管理、重复建设、相互交叉、效率不高问题的重要手段,也是科技服务平台信息化发展的重要趋势。由于科技云滞后于科技服务平台,数据资源集成与资源共享都相比离散平台更为复杂,基于科技云理清科技服务平台数据资源、服务功能、用户对象以及运行模式,成为建设科技云的前提。在剖析科技中介模式、众包模式、众创模式不同形式科技服务平台运行模式的基础上,以科技云集成思路为导向,剖析科技云平台数据资源、服务功能、用户对象,刻画政府主导模式下的科技云运行模式和企业主导模式下的科技云运行模式。研究指出科技云模式下,科技服务平台数据资源将以资源池形式集中呈现,科技服务将体现“一站式”服务特征,政府主导下的科技云运行模式与企业主导下的科技云运行模式将存在差异。
