In the context of the continuous integration and development of new-generation information technology (IT) and various industries, it is particularly important to pay attention to how the IT-affected income gap between urban and rural residents changes to affect the common wealth. This study conducts an empirical study based on 310 balanced panel data of inter-provincial China from 2012 to 2022 to investigate the specific impact mechanism of the increase in regional IT penetration on income disparity. The study finds that: 1) increased regional IT penetration widens the urban-rural and regional income gaps; 2) increased regional IT penetration widens the urban-rural and regional income gaps through the use of digital inclusive finance and deepening the digital divide, respectively. This study concludes that the government should improve the infrastructure of digital technology in rural areas as soon as possible, give full play to the inclusive and convenient role of digital inclusive finance, alleviate the digital divide between urban and rural areas, and reduce the ‘Matthew effect’, to facilitate sustainable development.
在新一代信息技术(IT)与各行业不断融合发展的背景下,关注IT如何影响城乡居民收入差距的变化,进而影响共同财富,显得尤为重要。本文基于2012 - 2022年中国省际间310个均衡面板数据进行实证研究,探讨区域信息技术普及率提高对收入差距的具体影响机制。研究发现:1)区域信息技术普及率的提高扩大了城乡和区域收入差距;2)区域信息技术普及率的提高分别通过数字普惠金融的使用扩大了城乡和区域收入差距,加深了数字鸿沟。本研究认为,政府应尽快完善农村数字技术基础设施,充分发挥数字普惠金融的包容性和便利性作用,缓解城乡数字鸿沟,减少“马太效应”,促进可持续发展。

Governments are major purchasers of goods and services globally. Although previous research highlights the role of government procurement in shaping business activities, the spillover effects on peer firms' innovation efficiency remain unexplored. Through a textual analysis that distinguishes innovation procurement from general government purchases, this study investigates the effects and underlying mechanisms of government innovation procurement on the innovation efficiency of peer firms. We find that government innovation procurement significantly enhances peer firms' innovation efficiency. Our mechanism analyses reveal that government innovation procurement sends positive signals, increasing peer firms' citations of procured firms' patents, thereby improving their innovation efficiency. The heterogeneity analyses indicate that this positive relationship is more pronounced when peer firms occupy comparable market positions, operate in regions with high-speed rail, have common analysts with the procured firms, and are classified as high-tech enterprises. We also find that central government procurement, cross-regional procurement, and evaluation methods involving “competitive consultation and negotiation” significantly enhance peer firms' innovation efficiency. Overall, our findings provide theoretical guidance and practical insights for governments to foster firm innovation and advance high-quality industrial development through innovation procurement.
各国政府是全球商品和服务的主要购买者。虽然以往的研究强调了政府采购在塑造企业活动中的作用,但其对同行企业创新效率的溢出效应仍未得到探讨。本文通过对创新采购与一般政府采购的实证分析,探讨了政府创新采购对同行企业创新效率的影响及其机制。研究发现,政府创新采购显著提高了同行企业的创新效率。我们的机制分析表明,政府创新采购发出了积极的信号,增加了同行企业对被采购企业专利的引用,从而提高了他们的创新效率。异质性分析表明,当同行企业占据可比的市场地位、在有高铁的地区运营、与被采购企业拥有共同的分析师、并被归类为高科技企业时,这种正相关关系更为明显。我们还发现,中央政府采购、跨区域采购和“竞争性协商谈判”评估方式显著提高了同行企业的创新效率。研究结果为政府通过创新采购促进企业创新、推动产业高质量发展提供了理论指导和实践启示。

We investigate political budget cycles in prefecture-level cities in China by leveraging cross-province variation in the timing of the Provincial Congress of the Communist Party, which is the most significant event for promoting and reappointing prefecture leaders. Our findings reveal strong evidence of a cyclical pattern, characterized by an increase in government spending leading up to the Congress, followed by a decrease afterward. This trend is particularly pronounced for infrastructure spending, which is a crucial driver of economic growth in China. Additionally, we examine China's multi-layer government hierarchy and explore heterogeneity across prefectures. Our analysis shows that these cycles are especially evident when promotion opportunities for prefecture leaders are most prominent. In terms of revenue sources, we do not observe significant cyclical patterns for in-budget revenues; however, we do find evidence of cycles in revenues from land sales, a vital source of off-budget revenues. Our study contributes to the literature by examining both the size of government and the allocation of public funds in order to uncover distinct political budget cycles at the prefecture level in China and highlighting the vertical incentives within the multi-layer government hierarchy.
​我们的研究结果有力地证明了一种周期性模式,其特点是国会召开前政府支出增加,随后又减少。这一趋势在基础设施支出方面尤为明显,而基础设施支出是中国经济增长的关键驱动力。此外,我们考察了中国的多层政府层级,并探讨了地级市之间的异质性。我们的分析表明,当地方领导的晋升机会最突出时,这些周期尤为明显。就收入来源而言,我们没有观察到预算内收入的显著周期性模式;然而,我们确实发现了土地销售收入周期的证据,这是预算外收入的重要来源。我们的研究通过考察政府规模和公共资金分配来揭示中国地级不同的政治预算周期,并强调多层次政府层级中的垂直激励,从而为文献做出了贡献。

This study employs ten-wave data from the China Health and Nutrition Survey (CHNS), covering the period from 1989 to 2015. It leverages the nationwide internet speed upgrading project launched in the early 21st century as an exogenous shock. Using this variation, we construct a difference-in-differences model to identify the causal effect of broadband internet access on children’s weight outcomes. The results show that broadband internet significantly increases the probability of children being overweight. Robustness tests support these results. The heterogeneity analysis reveals that the weights of children who are older and in urban are more affected by broadband internet. Mechanism analysis reveals that broadband internet increases children’s sedentary game activities time, decreases their physical activities time, and increases their snack intake and total energy intake. This study underscores the significance of coordinated regulation of children's gaming activities by parents, schools, communities, and the government, in order to effectively reduce children's online game time, mitigate the risk of overweight, and alleviate the economic burden associated with childhood overweight.
本研究采用中国健康与营养调查(CHNS)的十波数据,时间跨度为1989 - 2015年。它利用了21世纪初启动的全国互联网速度升级工程作为外生冲击。利用这一变化,我们构建了一个差异中的差异模型,以确定宽带互联网接入对儿童体重结果的因果影响。结果表明,宽带互联网显著增加了儿童超重的可能性。稳健性测试支持这些结果。异质性分析表明,年龄较大和城市儿童的体重受宽带网络的影响更大。机制分析表明,宽带网络增加了儿童久坐游戏活动时间,减少了儿童身体活动时间,增加了儿童零食摄入量和总能量摄入量。本研究强调了家长、学校、社区和政府协调监管儿童游戏活动的重要性,以有效减少儿童网络游戏时间,减轻超重风险,减轻与儿童超重相关的经济负担。

We propose a theory in which developing countries may lose from using duty exemptions to encourage processing trade. Our model features that (i) processing exports have a much lower domestic value-added share (DVAS) than ordinary exports and domestic sales, and (ii) domestic production exhibits external economies of scale. Consequently, the welfare effects of duty exemptions can be decomposed into two main components: (i) the direct effect captures welfare gains through reduced input costs and access to a greater variety of imported inputs. In contrast, (ii) the market size effect reflects welfare losses due to the contraction of domestic production, driven by the reallocation of labor away from high-DVAS production to low-DVAS processing production. We then calibrate our model to the Chinese firm-level data and aggregate trade flows across 47 economies. Our counterfactual analysis shows that the welfare losses associated with the market size effect outweigh the welfare gains from the direct effect, resulting in a reduction in China’s real income.
我们提出一种理论,其中发展中国家可能会因利用关税豁免来鼓励加工贸易而蒙受损失。我们的模型显示:(i)加工出口的国内增值份额(DVAS)远低于普通出口和内销,以及(ii)国内生产表现出外部规模经济。因此,免税的福利效应可以分解为两个主要组成部分:(i)直接效应通过降低投入成本和获得更多种类的进口投入来获得福利收益。相比之下,(ii)市场规模效应反映了劳动力从高dvas生产向低dvas加工生产的再配置所导致的国内生产收缩所造成的福利损失。然后,我们将我们的模型校准为中国企业层面的数据和47个经济体的总贸易流量。我们的反事实分析表明,与市场规模效应相关的福利损失超过了直接效应带来的福利收益,导致中国实际收入的减少。

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 impact of intelligent automation on subjective well-being and job satisfaction: A comparison between standard and nonstandard employment 智能自动化对主观幸福感和工作满意度的影响:标准和非标准就业的比较

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。

Global monetary policy shocks and the adaptation of supply chains 全球货币政策冲击与供应链适应

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。
