Twenty years of Hong Kong and Macao under Chinese rule: being absorbed under ‘one country,two systems’

This paper examines the implementation of ‘one country, two systems’ (1C2S) in the two former Western colonies, Hong Kong and Macao, as a policy innovation in managing inter-governmental relations of a large, diverse country like China. 1C2S embodies internal tensions because the Hong Kong and Chinese governments have multiple and often incompatible goals. After 20 years, these two special administrative regions (SARs) of China are gradually being absorbed.     

Inequality and entrepreneurial thresholds

We explore the relationship between inequality and entrepreneurial activity. Drawing on cross-sectional data from a largescale survey of the economic conditions of individuals across India, we develop a number of dimensions of inequality to explore empirically how inequality interacts with entrepreneurship, operationalized as self-employment or as employing other people. We find compelling evidence that there are thresholds to becoming self-employed, and even more so to assembling the combinations of resources and personal attributes required to become an employer. Greater inequality leaves more people unable to make the transition to self-employment, leaving casual laboring as the occupation of necessity. At the same time, inequality increases the number of employers in a society, by concentrating resources - particularly land and finance - enough for significant numbers of people to be able to cross this higher threshold. Lastly, greater differentiation into social or religious groups curtails the ability to cross either entrepreneurial threshold, presumably by limiting the extent and benefits of social networks of value for entrepreneurship.     

Concentration behavior of the penalized least squares estimator

Consider the standard nonparametric regression model and take as estimator the penalized least squares function. In this article, we study the trade‐off between closeness to the true function and complexity penalization of the estimator, where complexity is described by a seminorm on a class of functions. First, we present an exponential concentration inequality revealing the concentration behavior of the trade‐off of the penalized least squares estimator around a nonrandom quantity, where such quantity depends on the problem under consideration. Then, under some conditions and for the proper choice of the tuning parameter, we obtain bounds for this nonrandom quantity. We illustrate our results with some examples that include the smoothing splines estimator.     

Bridging the research-practice divide: Harnessing expertise collaboration in making a wider set of contributions

Understanding how we develop research contributions which go beyond conversations in the academic field is an enduring challenge. While much has been written on the importance of academic-practitioner relationships in the research process more is needed on conceptualizing how we develop a wider set of contributions. In this paper, we call for researchers to be reflective as to how different forms of expertise can be drawn on during collaborative relationships to bridge the research – practice divide. We develop a framework which combines different levels of expertise with varying forms of academic-practitioner collaboration to widen the impact of our research. Four strategies are proposed by which academics may leverage their expertise in collaborative relationships with practitioners to develop Research Impact and Contributions To Knowledge (RICK). These include: maintaining critical distance, promoting deeper engagement, developing prescience, and achieving hybrid practices. We discuss implementation approaches for each of these RICK strategies and suggest writing genres to help increase engagement by practitioners in research contributions.     

Valuing Initial Public Offerings Using Article 11 Pro Forma Financial Information in the Prospectus*

We investigate whether Article 11 pro forma financial information assists investors in valuing IPOs. While the SEC expects it to be helpful in assisting investment decisions, Article 11 pro forma financial information is based on registrants' understanding and assumptions, and registrants can exercise their own judgment when preparing pro forma financial statements. It is therefore an empirical question whether the information contained in pro forma financial statements is useful to investors. We examine the association between pro forma adjustments of earnings and book value of equity and the IPO offer value and find asymmetric results. While positive pro forma adjustments of earnings and book value of equity are positively associated with the IPO offer value, negative pro forma adjustments of earnings and book value of equity are negatively associated with the IPO offer value, suggesting that negative pro forma adjustments are priced as growth opportunities. Additional analyses reveal that the association between pro forma adjustments of book value of equity and the IPO offer value varies across different time periods and industries and that pro forma adjustments of book value of equity are initially mispriced by investors. In contrast, we do not find similar results for pro forma adjustments of earnings. Further empirical tests show that the asymmetric results of mispricing of pro forma adjustments of earnings and book value of equity may be explained by the requirements of Article 11 of Regulation S‐X for pro forma adjustments dictating that adjustments to earnings reflect only recurring items while adjustments to book value reflect both recurring and nonrecurring items.     

粤港澳大湾区制造业集聚与区域创新

以2009—2020年粤港澳大湾区11个城市为研究对象，探讨制造业集聚与区域创新的关系。研究发现，制造业集聚显著提高区域创新水平，可通过提高企业竞争这一路径实现。进一步分析发现，金融业集聚对区域创新发展具有显著的正向关系，金融产业和制造业产融协同集聚显著提高区域创新水平。研究结果表明，制造业集聚加剧产业内部企业创新竞争，带动区域创新发展，且金融业在创新中起到积极的推动作用。指出应鼓励区域企业创新竞争，优化营商环境，为产业融合发展提供保障。     

主办券商声誉机制对新三板挂牌企业会计信息质量影响的实证研究

新三板作为完善我国多层次资本市场的重要举措,在扩宽企业融资渠道、促进实体经济 发展等方面发挥着重要作用,然而信息披露质量不完善仍是制约新三板挂牌企业发展的重要因素。 基于企业会计信息质量视角,文章以 2006-2015 年新三板挂牌企业为研究样本,探讨主办券商声 誉机制是否能够发挥相应的治理作用。研究发现:高声誉主办券商促进了新三板挂牌企业信息披 露质量的提高,而且主要体现在市场化水平较高的省份;进一步研究表明主办券商声誉对信息质 量的治理作用在协议转让与创新层企业中更为明显。研究表明主办券商声誉能够对新三板挂牌企 业发挥相应的持续督导作用,对于如何提升新三板挂牌企业信息披露质量具有一定的借鉴意义。     

产业协同集聚影响全要素能源效率的“U”型关系再检验——基于集聚质量和深度的双重视角

利用2003—2019年省际面板数据,从集聚质量和深度的视角探究了产业协同集聚对地区全要素能源效率的影响,研究发现:产业协同集聚与地区全要素能源效率呈显著的"U"型关系;但相对于集聚深度而言,集聚质量的提高能够显著推动全要素能源效率较早越过拐点从而进入上升阶段。机制检验表明,当集聚质量和集聚深度均较低时,产业集聚会通过规模效应显著抑制全要素能源效率提升;而当集聚质量和深度均较高时,产业集聚则通过技术效应显著促进全要素能源效率提升。此外,对于不同地区而言,东部地区全要素能源效率能够率先摆脱产业协同集聚的抑制作用而进入上升阶段,中西部地区则需要在更高的集聚水平上实现全要素能源效率的攀升。     

混合所有制改革能有效化解国有企业产能过剩吗*

在深化国有企业混合所有制改革的政策背景下,相比于采用正向逻辑来研究国有企业与其他所有制企业产能过剩的成因与化解机制异同,本文通过逆向逻辑构造反事实因果推断,即国有企业经过混合所有制改革身份属性发生变更后产能过剩能否得到化解,来探究国有企业产能过剩的制度性成因。在实证分析中,本文通过PSM—多期DID方法识别了国有企业混合所有制改革对于其产能利用率的政策影响,分析了不同市场结构下国有企业规模对产能利用率影响的非线性关系,明晰了国有企业混合所有制改革化解产能过剩的作用途径,探究了产能过剩的制度性根源与衍生因素之间的传递效应。     

美国涉华诉讼对科技交流政策的影响和展望

美国司法部的“中国行动计划”实施三年以来,给中美两国正常的科技合作和学术交流带来了严重的影响和打击。近期美国一系列涉华诉讼引发了各界讨论,迫切敦促美国政府机构在保护知识安全的同时必须兼顾学术开放。美国最高科技政策决策机构决意出台实施指南,解决科技学术界的紧迫关切。中美两国领导人的线上会晤也就全球关切的议题进行交流合作,释放了积极信号,我国亦应鼓励科研人员继续进行跨国界的科学探索,努力促成和恢复中美在科技、人文等领域的正常交流合作。
