不同技术密度部门工业智能化的就业效应——来自中国制造业的证据

本文通过引入智能化资本重构任务模型,刻画不同技术密度部门中工业智能化升级对就业人数变动的影响机理,利用省级面板数据检验智能化升级对高、低技术密度部门就业的净影响效应,同时结合企业面板数据验证了智能化就业效应的传导渠道.研究表明:在中国当前发展阶段的高、低技术密度部门工业智能化升级都能够显著促进就业增加,且高技术密度部门的就业增加效应要明显高于低技术密度部门;在低技术密度部门工业智能化升级能够激发其利用技术扩散,而在高技术密度部门则倾向于通过生产规模扩张渠道,促进部门内部不同规模的就业增加;智能化升级的正向就业效应在非国有控股企业和东部地区企业中最为突出.     

How to inhibit a partner's strong and weak forms of opportunism: Impacts of network embeddedness and bilateral TSIs

This study investigates the moderating effects of a firm's network embeddedness and a partner's transactional specific investments (TSIs) on relationships between the firm's TSIs and its partner's strong- and weak-form opportunism, and compares the efficiency among these moderator variables. The regression results suggest that (1) a firm's TSIs are positively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively low; but (2) a firm's TSIs are negatively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively high. Furthermore (3) network embeddedness is more effective in inhibiting partner's weak-form opportunism than in inhibiting strong-form opportunism resulting from the firm's TSIs. Finally (4) with regard to the relationship between TSIs and weak-form opportunism, the negative moderating effect of network embeddedness is greater than the negative moderating effect of partner's TSIs. This study explains reasons why conflicting views exist about the relationship between TSIs and partner's opportunism, reveals the differences in the moderating effects of network embeddedness and partner's TSIs, and makes new contributions to both transaction cost theory and embeddedness literature. It also provides, for firms involved in TSIs in a buyer–supplier relationship, insightful managerial suggestions about ways to reduce their partner's varying forms of opportunism.     

中国“一带一路”战略定位的三个问题

"一带一路"战略在大方向基本清晰的情况下,在战略定位上仍然存在着三个有待进一步厘清的问题,包括:"一带一路"是全球战略还是区域战略?"一带一路"应以多重双边伙伴关系为基础还是应以跨区域整合为基础?"一带一路"战略应以西北方向为优先还是应以东南方向为优先?对这三个问题的诠释对于"一带一路"战略的推进有着极为重要的意义。这一战略虽然表现出了一定的全球战略的特征,但在本质上还是区域性的;其的推进必须以多重双边伙伴关系为基础。就目前的具体政治形势与经济形势来看,"一带一路"战略开拓西北面临更大的不确定性。     

CEO Stock‐Based Incentive Compensation and Firm Performance: A Quantile Regression Approach

This study employs the quantile regression model to examine the non‐monotonic impact of CEO stock‐based compensation on firm performance, using the data for U.S. non‐financial firms from 1993 to 2005. The results indicate that while the impact of CEO stock‐based pay on firm performance is positive for firms in the higher earnings quantile levels, the impact is negative for firms in the lower levels. In addition, the “V‐shaped” relationship between CEO stock‐based pay and firm performance satisfactorily explains the longstanding disagreement among earlier studies with regard to whether CEO stock‐based pay can enhance firm performance. Furthermore, the quantile‐varying pattern of the impact of stock‐based compensation on firm performance is robust after controlling for the industrial and yearly effects. It is also robust to the use of the pay‐for‐performance sensitivity as an alternative explanatory variable or the market‐based measure of performance as the dependent variable, or the consideration of the suspected endogenous problem between firm performance and stock‐based compensation.     

城市群高质量发展的理论逻辑与路径选择

现代化后发赶超要求以城市群作为主体空间形态,实现效率增进、功能跃升、均衡发展和开放合作.城市群正日益成为托起中国现代化的巨擘,目前我国19个城市群之间规模结构差异较大,以东部城市群发展质量最高.城市群发展失衡的原因在于,城市群城镇体系不合理、公共服务一体化存在障碍、区域一体化发展体制机制有待健全、城际间综合交通网络体系亟待完善.适应现代化发展要求,我国需要在城市群加快推动形成快速便捷的综合交通体系与一体化发展体制机制,以都市圈为载体优化城市群空间格局与推动城市群协同发展,加快构建包容共享的公共服务体系,提升城市群的开放发展水平,引领中国现代化发展.     

新冠疫情全球蔓延对我国就业的影响及机制分析

新冠疫情全球蔓延对需求端与供给端都造成巨大的冲击,评估此次疫情对我国就业的影响及机制分析变得重要.基于统计比较和使用DID模型,我们研究表明:(1)新冠疫情爆发前,我国总体失业率基本稳定,地区间失业差异趋于缩小;2020年疫情爆发后,我国城镇调查失业率出现明显上升,但其影响在下半年趋于缓解.(2)新冠疫情全球蔓延对我国就业市场产生显著不利的冲击,但对我国31个大城市就业的不利冲击要相对小于总体城镇.新冠疫情导致我国城镇调查失业率总体上升0.31个百分点,导致全国31个大城市调查失业率总体上升0.218个百分点.新冠疫情爆发4个月后我国就业受到的不利影响开始减小.(3)新冠疫情对我国制造业和服务业的经济活动均造成不利冲击,进而对我国就业造成显著不利的影响,且对我国服务业经济活动产生的不利冲击更大.据此,需要严格防控国内疫情反弹,提升一流的营商环境,对受疫情不利影响的企业和劳动者提供优惠政策支持,出台人力资本政策支持建立国家高端人力资本储备池,拓展数字贸易、数字平台等就业创业.     

股指成份股调整与公司盈余管理——基于一项准自然实验的研究

文章以沪深300指数2007年6月至2018年6月23次调整的成份股和同期公布的备选股为研究样本,考察了成份股调整对公司盈余管理的影响.研究发现:(1)与备选股相比,成份股调整后公司的应计盈余管理没有受到显著影响,而真实盈余管理水平则显著下降;(2)区分真实盈余管理的不同类型,成份股调整主要通过异常现金流降低了真实盈余管理水平;(3)在持续时间方面,成份股调整对真实盈余管理的影响在调入指数三年之后依然存在;(4)成份股调整降低真实盈余管理的作用在独立董事比例低和非国有企业样本中更加显著.上述结果表明,成份股调整的"监督效应"降低了公司的真实盈余管理水平,且在其他监督渠道较弱的情况下更加显著.文章丰富了成份股调整经济后果和盈余管理影响因素的研究,并有助于监管者和投资者认识股票指数调整对公司行为和会计信息的现实影响,以监管和防范投资风险.
