This paper measures the urban shape of Chinese prefecture-level cities and examines the impacts of its fragmentation on local innovation activity. Using a harmonized satellite nightlight dataset from 1999 to 2021, we delineate urban areas as polygons formed by adjacent bright grids at night. We decompose changes in a city's urban shape into two components: the dispersion of individual polygons, and the fragmentation characterized by the growing spatial separation between these polygons. Our empirical analysis reveals that deteriorating urban shape, which typically results in longer commutes for individuals to meet, is associated with fewer local patent grants, with urban fragmentation being the primary driver. Mechanism analysis reveals that intensified urban fragmentation disproportionately impedes collaborative innovation, primarily by elevating communication costs within inventor teams. These findings highlight the pivotal role of optimized urban spatial structures in fostering face-to-face interactions and knowledge spillovers essential for innovation ecosystems.
本文对中国地级市的城市形态进行了测度,并考察了城市碎片化对地方创新活动的影响。利用1999年至2021年的统一卫星夜间灯光数据集,我们将城市区域划分为夜间相邻明亮网格形成的多边形。我们将城市形态的变化分解为两个组成部分:单个多边形的分散,以及这些多边形之间日益增长的空间分离所带来的碎片化。我们的实证分析表明,城市形态的恶化通常会导致个人通勤时间的延长,这与地方专利授权的减少有关,而城市碎片化是主要驱动因素。机制分析表明,城市碎片化加剧不成比例地阻碍了协同创新,主要是通过提高发明人团队内部的沟通成本。这些发现强调了优化的城市空间结构在促进面对面互动和知识溢出方面的关键作用,这对创新生态系统至关重要。

The accelerating global adoption of intelligent automation (IA) technologies is fundamentally transforming economic structures and reshaping individual lifestyles. Despite intense debate regarding the societal impacts of IA, including both beneficial and adverse effects, empirical evidence on its net influence on multidimensional well-being outcomes remains scarce. Drawing on a nationally representative dataset from China (2018–2020), we employed multilevel probit models with instrumental variables to investigate how IA influences subjective well-being (SWB) and job satisfaction (JS), differentiating between standard and nonstandard employment contexts. Our findings revealed distinct nonlinear relationships: an inverted U-shaped pattern between IA and SWB, versus a U-shaped relationship between IA and JS, with turning points above the 35th and 80th percentiles of IA intensity distribution, respectively. These contrasting trajectories suggest that IA’s impacts vary considerably between consumption utility and production utility domains. The results demonstrate significant heterogeneity in the well-being effects of IA across different forms of employment. Specifically, within standard employment arrangements, IA exerts strong marginal diminishing effects on JS, though with an earlier turning point as IA intensity increases. Moreover, our counterfactual decomposition analysis verifies that IA contributes to narrowing the overall SWB and JS gaps between standard and nonstandard forms of employment by approximately 13% and 19%, respectively. Our mediation analysis identified three distinct transmission mechanisms — psychological factors, social interactions, and structural inequality — through which IA influences well-being, with mental exhaustion and actual inequality accounting for 38% and 30% of the total negative effect of IA on JS, respectively. These findings suggest that policy interventions would ensure balanced technological integration to maximize technology’s welfare benefits while mitigating its polarizing tendencies. This study provides important implications for understanding how technological transformation shapes human well-being across increasingly segmented global labor markets.
智能自动化(IA)技术的全球加速采用正在从根本上改变经济结构和重塑个人生活方式。尽管关于内部投资的社会影响(包括有益和不利影响)存在激烈争论,但关于其对多维福祉结果的净影响的经验证据仍然很少。利用中国(2018-2020)具有全国代表性的数据集,我们采用带有工具变量的多层次probit模型来研究IA如何影响主观幸福感(SWB)和工作满意度(JS),并区分标准和非标准就业环境。我们的研究结果揭示了明显的非线性关系:IA和SWB之间呈倒u型关系,而IA和JS之间呈u型关系,拐点分别高于IA强度分布的第35和第80百分位。这些对比轨迹表明,内部投资的影响在消费效用和生产效用领域之间差异很大。研究结果表明,在不同形式的就业中,内部投资对幸福感的影响存在显著的异质性。具体来说,在标准的就业安排中,IA对JS有很强的边际递减效应,尽管随着IA强度的增加,转折点会提前。此外,我们的反事实分解分析证实,IA有助于将标准和非标准就业形式之间的整体SWB和JS差距分别缩小约13%和19%。我们的中介分析确定了三种不同的传递机制——心理因素、社会互动和结构性不平等——IA通过这些机制影响幸福感,其中精神耗竭和实际不平等分别占IA对JS的总负面影响的38%和30%。这些研究结果表明,政策干预可以确保平衡的技术整合,以最大限度地提高技术的福利效益,同时减轻技术的两极分化趋势。这项研究为理解技术转型如何在日益分化的全球劳动力市场中塑造人类福祉提供了重要启示。

Robots and cost of equity: Evidence from China 机器人和公平成本:来自中国的证据

There are two competing perspectives regarding the nexus between robotics adoption and the cost of equity. One view posits that robotics adoption allows firms to cut more jobs when necessary, leading to decreases in the cost of equity, thanks to technological advances and improved efficiency. Another view, however, postulates that robotics adoption may disrupt workforce morale, prompting shareholders to demand higher returns to offset perceived operational risks, thereby increasing the cost of equity. To empirically examine these conflicting effects, this study analyzes data from Chinese publicly traded firms spanning 2006 to 2019. Leveraging industry-level metrics on robotics adoption from the International Federation of Robotics and a panel of Chinese listed firms, this study identifies a robust negative association between robotics adoption and the cost of equity. Mechanism analysis reveals that robotics impacts firms' cost of equity via two opposing channels: operating leverage and employee satisfaction, with the former dominating the latter. This research enriches a growing body of literature on automation technologies by offering solid evidence from Chinese firms and sheds light on how robotics adoption influences firms' cost of equity.
关于采用机器人技术与公平成本之间的关系,有两种相互竞争的观点。一种观点认为,由于技术的进步和效率的提高,采用机器人技术可以让企业在必要时裁减更多的工作岗位,从而降低股权成本。然而,另一种观点认为,采用机器人技术可能会破坏员工士气,促使股东要求更高的回报来抵消感知到的运营风险,从而增加股权成本。为了实证检验这些相互冲突的影响,本研究分析了2006年至2019年中国上市公司的数据。利用国际机器人联合会(International Federation of robotics)和一组中国上市公司关于机器人采用的行业指标,本研究发现机器人采用与股权成本之间存在强烈的负相关关系。机制分析表明,机器人技术通过经营杠杆和员工满意度两个相反的渠道影响企业股权成本,前者主导后者。本研究通过提供来自中国企业的确凿证据,丰富了越来越多关于自动化技术的文献,并揭示了机器人的采用如何影响企业的股权成本。

Though the goal-setting theory has attracted much attention, current research neglects how the principal-agent structure shapes agents' target-setting. This study estimates how principal-agent incentive arrangements affect target-setting from the micro-level perspective of local officials. Using a novel fuzzy regression discontinuity design, it shows that China's political selection system creates a significant downward discontinuity in city-level agents' political career advancement prospects at the 55-year-old age threshold, and city agents with weaker age-based career incentives set lower GDP growth targets than those with stronger ones. Moreover, this effect decreases when these agents are under increased pressure to curb environmental pollution. The subperiod analysis suggests that the strategic target-setting behavior of local agents evolves dynamically in response to changes in performance evaluation criteria. It contributes to the target-setting theory in principal-agent contexts, featuring a rigorous political promotion ladder and trade-offs associated with multiple tasks.
虽然目标设定理论备受关注,但目前的研究忽略了委托-代理结构如何影响主体的目标设定。本研究从地方官员微观层面的角度,对委托代理激励安排对目标设定的影响进行了估计。采用一种新颖的模糊回归不连续设计,表明中国的政治选择制度在55岁阈值下对城市一级代理人的政治职业发展前景产生了显著的向下不连续,年龄职业激励较弱的城市代理人设定的GDP增长目标低于年龄职业激励较强的城市代理人。此外,当这些药物面临更大的抑制环境污染的压力时,这种效果会减弱。子周期分析表明,局部代理的战略目标设定行为随着绩效评价标准的变化而动态演化。它为委托-代理情境下的目标设定理论做出了贡献,该理论具有严格的政治晋升阶梯和与多个任务相关的权衡。

This paper examines how global monetary policy shocks (MPS) transmitted through trade networks affect supply chain adaptation of Chinese firms. When exposed to higher supplier-side MPS, firms experience significantly higher separation rates and lower foreign entry rates. Our findings remain robust across a range of alternative MPS measures. In response, firms shift their sourcing from high-interest-rate countries to low-interest-rate countries, but they do not re-shore. We show that trade credit and price adjustment by suppliers are important for explaining the restructuring. The disruption is more likely driven by customer decisions. Moreover, heterogeneities show that firms with stricter credit constraints are more sensitive to MPS, while longer-duration supply chain relationships show greater resilience. The supply chain adaptation induced by MPS also leads to adverse real economic outcomes for imports, exports, and profitability.
本文考察了通过贸易网络传导的全球货币政策冲击对中国企业供应链适应的影响。当面对更高的供应商方MPS时,公司会经历显著更高的分离率和更低的外国进入率。我们的研究结果在一系列替代MPS措施中仍然是强有力的。作为回应,企业将他们的采购从高利率国家转移到低利率国家,但他们不会将资源回流。我们发现贸易信贷和供应商的价格调整对解释结构调整很重要。这种颠覆更有可能是由客户的决定驱动的。此外,异质性表明,信贷约束更严格的企业对MPS更敏感,而持续时间更长的供应链关系表现出更大的弹性。MPS诱导的供应链适应也会对进口、出口和盈利能力产生不利的实际经济结果。

This paper constructs high-frequency monetary policy shocks for China using intra-day government bond futures price changes around policy announcements. Exploiting the PBC’s unique announcement protocol (2017–2019), we isolate exogenous policy surprises and trace their dynamic effects. Policy surprises have transient impacts on interbank markets but induce persistent adjustments in broader financial markets and real outcomes, indicating transmission through a signaling channel. Further decomposition reveals a crucial asymmetry: pure policy shocks and policy stance changes are persistently contractionary while shocks conveying the central bank’s information are modestly expansionary. Our findings show that overall policy impact reflects competing signals and provide a framework for identifying central bank communication’s dual role in signaling both policy stance and economic outlook in emerging markets with evolving price-based regimes.
本文利用政策公告前后的国债期货价格变动,构建了中国货币政策高频冲击模型。利用中国人民银行独特的公告协议(2017-2019),我们隔离外生政策意外并追踪其动态影响。政策意外对银行间市场的影响是短暂的,但会在更广泛的金融市场和实际结果中引发持续的调整,表明这种调整是通过信号渠道传导的。进一步的分解揭示了一种至关重要的不对称:纯粹的政策冲击和政策立场的变化是持续收缩的,而传达央行信息的冲击是适度扩张的。我们的研究结果表明,总体政策影响反映了相互竞争的信号,并提供了一个框架,以确定央行沟通在新兴市场的双重作用,即在基于价格的机制不断发展的情况下,传达政策立场和经济前景。

The recent major judicial reforms in China involve implementing a judge quota and personnel management system. To date, little is known about the impact of the reforms. Using over 14 million Chinese court judgments data from 2014 to 2018, this article evaluates the connections between qualified judges and labor specialization and judicial efficiency and quality. This study found that the judge quota reform in China has improved judicial efficiency and quality due mainly to the personnel classification management system rather than the reappointed judges. By introducing task-specific returns to specialization in the judicial system, the personnel classification management system has allowed judges to concentrate on their adjudicative tasks instead of administrative and secretarial duties and thereby improving judicial performance. Institution design plays an important role in optimizing resource allocation and improving efficiency. Implications for policy and future research are discussed.
中国最近的重大司法改革包括实行法官配额制和人事管理制度。迄今为止,人们对改革的影响知之甚少。本文利用2014年至2018年的1400多万份中国法院判决数据,评估了合格的法官与劳动专业化、司法效率和质量之间的关系。本研究发现,中国法官名额改革之所以能够提高司法效率和质量,主要是由于人员分类管理制度,而不是由于法官的连任。通过在司法系统中引入按任务分配的专业化回报,人员分类管理制度使法官能够集中精力完成审判任务,而不是行政和秘书职责,从而提高司法绩效。制度设计在优化资源配置、提高效率方面具有重要作用。对政策和未来研究的影响进行了讨论。

The effect of family size on intergenerational support for elderly parents and their life expectancy: Evidence from China’s “Later, Longer, Fewer” campaign 家庭规模对老年父母代际赡养及其预期寿命的影响:来自中国“晚、长、少”运动的证据

This study documents increased life expectancy among elderly parents in China whose adult children were exposed to the “Later, Longer, Fewer” (LLF) family planning campaign in the 1970s. We leverage the variation in policy exposure at the province, urban, and birth-cohort level to understand the extent to which the LLF campaign has affected social networks and intergenerational support for elderly parents. The plausible channels that may impact life expectancy are living arrangements, visits, and financial transfers. Using the 2011 China Health and Retirement Longitudinal Study, we identify adults of childbearing age who were exposed to the LLF campaign and whose fertility was reduced. We find that greater LLF exposure increases the likelihood of the wife’s parents co-residing in her household. The increase in elderly support, however, is largely manifested through more visits and financial transfers from their sons’ families, which is unsurprising in a patrilineal society. Most gains are driven by rural households.
本研究记录了20世纪70年代中国实行“晚、长、少”(LLF)计划生育运动后,中国老年父母的预期寿命增加。我们利用省、城市和出生队列水平的政策暴露变化来了解LLF运动对社会网络和对老年父母的代际支持的影响程度。可能影响预期寿命的合理渠道是生活安排、访问和财政转移。利用2011年中国健康与退休纵向研究,我们确定了暴露于LLF运动的育龄成年人,其生育能力降低。我们发现,更大的LLF暴露增加了妻子的父母共同居住在她的家庭的可能性。然而,老年人赡养的增加主要体现在更多的探望和儿子家庭的经济转移上,这在父系社会中并不奇怪。大部分收益是由农村家庭推动的。

Socio-emotional skills are essential for entrepreneurial behavior and firm performance, yet little is known about how entrepreneurial traits are associated with major life events such as migration. This study investigates the relationship between internal migration experience (IME) and the locus of control (LOC) among entrepreneurs, a psychological trait with significant implications for various life and organizational outcomes. We first develop a theoretical framework to explore how migration may relate to entrepreneurs' LOC. Using nationally representative datasets from China, we compare entrepreneurs with IME who returned to their hometowns with those who have never migrated. The results show robust evidence that returnees exhibit stronger internal LOC than non-migrants, partially explaining the positive link between migration and entrepreneurial behaviors. This observed relationship is more pronounced among those who migrated earlier in life and appears weaker among individuals with prolonged migration durations. The positive association is also more evident among male entrepreneurs, those born after 1980, members of the ethnic majority, and entrepreneurs from smaller cities. Mechanism analysis further suggests that while IME is linked to health deterioration and weakened origin-based social networks, it is also associated with gains in work experience, managerial skills, cultural assimilation, and socioeconomic improvement, which contribute to strengthening internal control beliefs. Our findings underscore the relevance of internal migration for entrepreneurial behavior, particularly through the lens of socio-emotional skills, and suggest the importance of migration policies for inclusive urban development.
社会情感技能对创业行为和公司绩效至关重要,但人们对创业特质与移民等重大生活事件之间的关系知之甚少。摘要本研究探讨企业家的内部迁移经验(IME)与控制点(LOC)之间的关系,控制点是一种对各种生活和组织结果具有重要影响的心理特质。我们首先建立了一个理论框架来探讨移民与企业家LOC之间的关系。我们使用来自中国的具有全国代表性的数据集,将返回家乡的IME企业家与从未移民的企业家进行了比较。研究结果表明,海归比非移民表现出更强的内部LOC,这部分解释了移民与创业行为之间的正相关关系。这种观察到的关系在那些迁移时间较早的人中更为明显,而在迁移时间较长的个体中则显得较弱。这种积极的联系在男性企业家、1980年以后出生的人、少数民族成员和小城市的企业家中也更为明显。机制分析进一步表明,虽然IME与健康恶化和基于起源的社会网络减弱有关,但它也与工作经验、管理技能、文化同化和社会经济改善的增加有关,这些都有助于加强内部控制信念。我们的研究结果强调了内部移民与创业行为的相关性,特别是通过社会情感技能的视角,并提出了移民政策对包容性城市发展的重要性。

Financial liberalization and capital allocation in China 中国的金融自由化与资本配置

The aim of this paper is to quantitatively evaluate the consequences of capital account liberalization on China’s real economy and capital allocations when economic uncertainty surges. We construct a heterogeneous-agent open economy dynamic general equilibrium model featuring financially constrained households and multiple types of saving instruments, including housing assets and foreign assets. Capital account liberalization offers China’s domestic households more options for purchasing foreign assets as an alternative saving instrument, enhancing consumption-smoothing capacities and mitigating the crowding-out effect of the housing sector on the real economy. The quantitative analysis further indicates that in the short run, the reduced investment demand for housing assets caused by financial liberalization leads to more capital being allocated to the domestic real sector, and in the long run, a trade-off exists between smoothing consumption and promoting output. When uncertainty increases, capital account liberalization can improve social welfare and facilitate capital flows from the housing sector to the real sector.
本文的目的是定量评估当经济不确定性激增时,资本账户自由化对中国实体经济和资本配置的影响。本文构建了一个具有财务约束家庭和多种储蓄工具(包括住房资产和外国资产)的异构主体开放经济动态一般均衡模型。资本账户自由化为中国家庭购买外国资产提供了更多选择,作为另一种储蓄工具,增强了消费平滑能力,缓解了房地产部门对实体经济的挤出效应。定量分析进一步表明,在短期内,金融自由化导致的住房资产投资需求减少导致更多的资本被配置到国内实体部门,在长期内,平滑消费和促进产出之间存在权衡关系。当不确定性增加时,资本账户自由化可以改善社会福利,促进资本从住房部门流向实体部门。
