第三方支付对商业银行盈利水平影响的实证分析——基于系统GMM模型

基于2012~2017年41家商业银行相关数据构建动态面板系统GMM模型,从实证角度分析第三方支付对商业银行盈利水平的影响。结果表明:总体而言,第三方支付降低了商业银行盈利能力;分类来看,第三方支付对全国性商业银行有积极影响,但对地方性商业银行有较大的负面影响。     

企业数字化转型对商业模式创新的影响

基于组织变革理论与知识基础观,引入知识管理与企业家导向变量,探讨企业数字化转型对商业模式创新的影响机制与情境效应。结果表明：①数字化转型对商业模式创新存在显著正向影响;②知识管理在数字化转型对商业模式创新的影响过程中发挥中介作用;③相比于低水平企业家导向,高水平企业家导向会强化数字化转型与知识管理的关系,弱化知识管理与商业模式创新的关系。     

技术多元化、发明者网络嵌入与军民融合企业技术创新效率

采用随机前沿模型对2015—2020年中国内地107家军民融合企业技术创新效率进行测算,并基于军民融合企业专利数据构建技术多元化、发明者网络嵌入（结构洞和网络密度）等指标。运用社会网络分析与多元线性回归方法,实证分析技术多元化、发明者网络嵌入及两者交互作用、结构洞与网络密度的互补关系/平衡关系对军民融合企业技术创新效率的影响。结果发现：技术多元化、结构洞及两者交互作用对军民融合企业技术创新效率具有正向影响;网络密度及其与技术多元化的交互作用对军民融合企业技术创新效率具有负向影响;网络密度和结构洞的互补关系会抑制军民融合企业技术创新效率提升,但两者在军民融合企业内部的平衡关系能够促进军民融合企业技术创新效率提升。     

城市品牌与流动人口就业选址决策

城市品牌作为保持和增强城市竞争力,加强地区间战略关联和聚集高端生产要素的重要管理工具,已经成为各地城市建设的重点方向。文章以“全国文明城市”的评比作为准自然实验,利用2013-2017年全国流动人口动态监测调查数据,探讨了城市品牌对流动人口就业选址决策的影响机理。研究结果显示,当城市获得“全国文明城市”称号后,流动人口到该城市就业的概率显著提高1.13%。进一步的机制检验结果显示,入选“全国文明城市”后,该城市公共品供给增加,环境质量提高和就业机会增多,同时短期内流动人口对文明城市的关注度显著提高,两者共同促使流动人口向文明城市集聚。而“全国文明城市”品牌的正向影响主要集中在互联网基础较好的户籍省份、年轻人群体或育有子女的群体之中。流动人口来到获得“全国文明城市”称号的地区工作之后,他们的公共医疗保险本地参保概率与子女本地入学概率均显著提高,对城市的满意度与融入当地的意愿也显著提升。文章的研究结论对地方政府出台相关人才集聚政策具有一定的启示意义。     

基于SEM模型的制造业供应链稳定发展影响因素研究

中国制造业体量虽大,但产业供应链自主可控性和安全性尚未达到我国制造强国的发展要求。本文以制造业供应链为对象,通过系统地界定影响制造业供应链稳定发展的因素,并基于问卷调查法采集的样本数据,运用结构方程模型和AMOS软件,构建数字化转型程度、信息共享程度、供应链韧性程度和外部环境因素四大潜变量及其观测变量的指标假设模型,研究制造业供应链稳定发展的影响因素。研究发现,四大影响因素对制造业供应链稳定发展均有着正向的影响,而且根据路径的总影响效应可区分其影响力的大小。本文为制造业供应链稳定发展提供了微观证据,并期望为制造业供应链上各节点企业的发展提供一定启示。     

Riskiness of Real Estate Development: A Perspective from Urban Economics and Option Value Theory

In this article, we define a new construct for urban economic and investment analysis, which revisits the conventional wisdom that investment in real estate development is riskier than investment in stabilized property assets. This new construct, referred as a “development asset value index” (DAVI), is a value index for newly developed properties (only) in a given geographical property market. It tracks longitudinal changes in the highest and best use (HBU) value of locations, and it reveals developer and landowner behavior taking advantage of the optionality inherent in land ownership. In particular, the DAVI reflects developers' use of flexibility in the exercise of the call option to (re)develop the property to any legal use and density. We empirically estimate a DAVI for commercial property (i.e., central locations) and compare it with a corresponding traditional transaction‐price‐based property asset price index (PAPI) corrected for depreciation. We believe that the difference primarily reflects the realized value of flexibility in land development. We find that the DAVIs display greater value growth and are smoother over time and less cyclical than their corresponding PAPIs for the same locations. This suggests that developers successfully use flexibility, and that development may be riskier than stabilized property investment due primarily only to leverage effects (construction costs). Practical implications are also discussed.     

The online laboratory: conducting experiments in a real labor market

Online labor markets have great potential as platforms for conducting experiments. They provide immediate access to a large and diverse subject pool, and allow researchers to control the experimental context. Online experiments, we show, can be just as valid—both internally and externally—as laboratory and field experiments, while often requiring far less money and time to design and conduct. To demonstrate their value, we use an online labor market to replicate three classic experiments. The first finds quantitative agreement between levels of cooperation in a prisoner’s dilemma played online and in the physical laboratory. The second shows—consistent with behavior in the traditional laboratory—that online subjects respond to priming by altering their choices. The third demonstrates that when an identical decision is framed differently, individuals reverse their choice, thus replicating a famed Tversky-Kahneman result. Then we conduct a field experiment showing that workers have upward-sloping labor supply curves. Finally, we analyze the challenges to online experiments, proposing methods to cope with the unique threats to validity in an online setting, and examining the conceptual issues surrounding the external validity of online results. We conclude by presenting our views on the potential role that online experiments can play within the social sciences, and then recommend software development priorities and best practices.     

CLASSIFICATION PROBLEMS AND THE DIVIDING LINE BETWEEN GOVERNMENT AND THE MARKET: AN EXAMINATION OF NHS FOUNDATION TRUST CLASSIFICATION IN THE UK

ABSTRACT: In this paper we argue that national accounting categories provide an inadequate basis for evaluating differences between public and private sector services. This is because accounting categories rely on economic concepts such as market price but do not take account of substantive public policy goals such as universality. The argument has important consequences for the structures and systems of delivery especially where nonprofit providers and social enterprise models are substituted for public bodies formerly integrated into the government's delivery system. Using an example taken from the UK's National Health Service, we show that the mechanisms for ensuring universality through redistribution are not sufficiently taken into account for classification purposes.
