Understanding how intellectual-property protection shapes employment is vital for policies that spur sustainable job growth. Most studies examine IP protection’s role in innovation, leaving its employment effects underexplored. Using data from Chinese listed firms between 2006 and 2019, this paper adopts a stacked difference-in-differences approach to evaluate the effect of the National Intellectual Property Model City Policy on firm-level employment. The results show that the policy significantly increases employment in pilot-city firms, and the impact is stronger for companies that already employ more R&D personnel (direct effect), channel additional capital into scaling up production (vertical innovation), or generate new products and services that open up fresh positions (horizontal innovation). Further analysis indicates that the policy reduces the proportion of low-skilled workers, signaling an upgrading of workforce skills. Heterogeneity analysis based on machine learning shows that firm size, educational infrastructure, and ecological environment further amplify the policy's employment effects. These findings suggest that strengthening intellectual property regimes and improving urban infrastructure can foster job growth and optimize policy outcomes.
了解知识产权保护如何影响就业对刺激可持续就业增长的政策至关重要。大多数研究考察的是知识产权保护在创新中的作用,对其就业效应的探索不足。本文利用2006 - 2019年中国上市公司的数据,采用叠加差分法评估了国家知识产权示范城市政策对企业层面就业的影响。结果表明,该政策显著增加了试点城市企业的就业,并且对那些已经雇佣了更多研发人员(直接效应)、将额外资本用于扩大生产(垂直创新)或开发新产品和服务以开辟新岗位(横向创新)的公司的影响更大。进一步分析表明,该政策降低了低技能工人的比例,标志着劳动力技能的提升。基于机器学习的异质性分析表明,企业规模、教育基础设施和生态环境进一步放大了政策的就业效应。这些发现表明,加强知识产权制度和改善城市基础设施可以促进就业增长并优化政策成果。

Promoting green economic efficiency has become a central objective of China's sustainable transition, requiring the coordinated deployment of multiple policy tools. This study investigates how environmental regulation and green finance jointly shape green development outcomes, and whether their combined application generates benefits beyond their individual effects. Building on a pressure-resource perspective, we develop a theoretical framework and conduct empirical tests using a balanced panel covering 287 prefecture-level cities from 2008 to 2022. The model assesses both separate and joint policy effects and further identifies the underlying transmission channels through emission constraints, innovation-driven growth, and financing support. The results show that although each policy independently improves green economic efficiency, their joint implementation further strengthens and enhances the effect, producing a synergy-enhancing outcome. Mechanism analysis further reveals that the synergy operates mainly through constraints on emissions, enhanced innovation dynamics, and targeted financing support. The positive effects are evident across varying levels of environmental pollution and energy dependence. However, in regions with a low level of industrial structure upgrading, the reinforcing effect of policy interaction weakens, suggesting that structural rigidities limit the potential gains from policy overlap.
提高绿色经济效率已成为中国可持续转型的核心目标,需要多种政策工具的协调部署。本研究探讨了环境监管和绿色金融如何共同塑造绿色发展成果,以及它们的联合应用是否产生了超出其单独效应的效益。基于压力-资源视角,我们构建了理论框架,并利用覆盖287个地级市(2008 - 2022年)的均衡面板进行了实证检验。该模型评估了单独政策和联合政策的影响,并通过排放约束、创新驱动增长和融资支持进一步确定了潜在的传导渠道。结果表明,虽然各政策单独提高了绿色经济效率,但它们的联合实施进一步加强和提高了效果,产生了协同增效的结果。机制分析表明,协同效应主要通过排放约束、创新动力增强和定向融资支持来实现。在不同程度的环境污染和能源依赖中,积极影响是明显的。然而,在产业结构升级水平较低的地区,政策互动的强化效应减弱,说明结构性刚性限制了政策重叠的潜在收益。

This study examines whether and how artificial intelligence engagement affects firms’ deviations from historically expected performance. Using data from non-financial A-share listed firms in China, this study constructs a firm-level indicator of AI engagement based on annual report text and empirically examines its impact on the historical performance expectation gap. The analysis further investigates the underlying transmission channels and the moderating role of the macro policy environment. The results show that higher AI engagement is associated with smaller deviations from historical performance expectations, suggesting that AI enhances firms’ ability to manage expectations and align outcomes with historical benchmarks. Mechanism analysis reveals that this effect operates indirectly through improvements in both supply chain stability and top management team consistency, highlighting the dual governance value of AI across internal and external dimensions. Moreover, the moderating effect analysis finds that the role of AI becomes more pronounced under accommodative monetary policy conditions, indicating that supportive policy environments amplify the effectiveness of AI-based governance. This study contributes to the literature by offering a micro-level governance perspective on the economic consequences of AI, and provides empirical insight into the dynamic interaction between technological integration, expectation management, and institutional conditions.
本研究考察了人工智能参与是否以及如何影响公司偏离历史预期绩效。本研究利用中国非金融类a股上市公司的数据,基于年报文本构建了企业层面的人工智能敬业度指标,并实证检验了其对历史业绩预期差距的影响。分析进一步探讨了潜在的传导渠道和宏观政策环境的调节作用。结果表明,人工智能参与度越高,与历史业绩预期的偏差越小,这表明人工智能增强了公司管理预期的能力,并使结果与历史基准保持一致。机制分析表明,这种效应通过改善供应链稳定性和高层管理团队一致性间接起作用,突出了人工智能在内部和外部维度上的双重治理价值。此外,调节效应分析发现,在宽松的货币政策条件下,人工智能的作用更加明显,这表明支持性的政策环境放大了人工智能治理的有效性。本研究对人工智能的经济后果提供了微观层面的治理视角,并对技术集成、期望管理和制度条件之间的动态相互作用提供了实证见解,从而为文献做出了贡献。

This study investigates the dynamic nexus between supply chain digitalization (SCD) and energy utilization efficiency (EUE) as a key pathway to improving energy resilience in urban China. Utilizing a Difference-in-Differences (DID) econometric approach on panel data from 276 cities spanning 2006 to 2021, our analysis reveals that SCD significantly enhances EUE through multiple channels: governmental support for innovation, advancements in green technological development, and stimulation of entrepreneurial ecosystems. The study finds that cities with robust technological infrastructures, diversified economic bases, and excellent business environment experience more pronounced efficiency gains, while regions with stringent environmental regulations show a “squeeze effect” that limits digitalization’s positive impact on energy performance. These findings underscore the need for adaptive, policy-driven frameworks that harmonize digital transformation with sustainable energy strategies, offering actionable insights for policymakers and stakeholders aiming to bolster energy resilience and secure energy supply chains.
本研究探讨了供应链数字化与能源利用效率之间的动态联系,并将其作为提高中国城市能源弹性的关键途径。利用对276个城市2006年至2021年面板数据的差异中差(DID)计量经济学方法,我们的分析表明,SCD通过多个渠道显著提高了欧洲经济利用效率:政府对创新的支持、绿色技术发展的进步和创业生态系统的刺激。研究发现,拥有强大的技术基础设施、多样化的经济基础和良好的商业环境的城市,效率的提高更为明显,而环境法规严格的地区则表现出“挤压效应”,限制了数字化对能源绩效的积极影响。这些研究结果强调,需要建立适应性、政策驱动的框架,使数字化转型与可持续能源战略相协调,为旨在增强能源弹性和保障能源供应链安全的政策制定者和利益相关者提供可行的见解。

In the context of the global transition to a low-carbon economy, a key issue in balancing environmental regulation with the allocation of labour skills is how carbon market policies reshape the structure of labour demand through technological pathways. This study employs data from listed Chinese manufacturing companies from 2011 to 2023 and utilises a multi-period difference-in-differences (DID) approach to examine the impact of carbon market pilot policies. The findings indicate that these policies significantly promote firms’ skill premiums. Further mechanism analysis reveals that carbon emissions trading policies, by exerting regulatory pressure, incentivise firms to adopt robotics to enhance productivity. Consequently, firms' demand for high-skilled labour increases significantly, while the demand for low-skilled labour decreases. This study offers novel empirical evidence on the interaction between carbon market policies and labour market dynamics, providing policy insights to support the government in effectively responding to changes in the employment structure and promoting adaptive adjustments in the labour market during the green transition process.
在全球向低碳经济转型的背景下,平衡环境监管与劳动力技能配置的一个关键问题是碳市场政策如何通过技术途径重塑劳动力需求结构。本研究采用2011年至2023年中国制造业上市公司的数据,采用多期差分法(DID)考察碳市场试点政策的影响。研究结果表明,这些政策显著促进了企业的技能溢价。进一步的机制分析表明,碳排放交易政策通过施加监管压力,激励企业采用机器人技术来提高生产率。因此,企业对高技能劳动力的需求显著增加,而对低技能劳动力的需求减少。本研究为碳市场政策与劳动力市场动态之间的相互作用提供了新的实证证据,为支持政府在绿色转型过程中有效应对就业结构变化和促进劳动力市场的适应性调整提供了政策见解。

Geopolitical events, such as the Russia–Ukraine conflict, accelerate global energy trade reallocation and supply chain restructuring. Oil shocks spread through global production networks via trade flows reorganization and production consumption. However, existing studies have not clearly described the process by which shocks generate initial disturbances through trade channels and undergo nonlinear transmission through production channels. This study constructs the MRIONFCS (multi-regional input-output network integrated with non-failure cascading spreading model) framework to simulate the dynamic transmission of oil shocks triggered by the trade reallocation of Russian oil through trade-production dual channels. By quantifying the economic impacts of shocks across 26 sectors in 189 economies, the study finds that the combined effects of trade centralization and geopolitical divergence exacerbate the uneven distribution of shocks. Asia (e.g., India, China) is the primary beneficiary of positive shocks, achieving cross-sectoral gains through industrial chain coupling. Europe (e.g., Germany, Italy) becomes a concentrated zone of negative shocks, with some regions experiencing persistent negative impacts due to refinery technologies locked into Russian Urals crude oil and slow energy transitions. At the same time, geographically critical small and medium-sized countries play counterintuitive roles in shock diffusion. Strategic hub countries such as Tunisia exhibit significantly higher amplification effects on shocks compared to large economies like India, acting as amplifiers for nonlinear shock transmission. This study reveals that the synergy between industrial structures and geopolitical strategies leads to resilience disparities among countries facing shocks, providing policy guidance for global energy-industry collaborative governance.
俄乌冲突等地缘政治事件加速了全球能源贸易的重新配置和供应链的重构。石油冲击通过贸易流动、重组和生产消费在全球生产网络中传播。然而,现有的研究并没有清楚地描述冲击通过贸易渠道产生初始干扰并通过生产渠道进行非线性传递的过程。本研究构建了MRIONFCS(多区域投入产出网络集成无故障级联扩散模型)框架,通过贸易-生产双渠道模拟俄罗斯石油贸易再分配引发的石油冲击的动态传递。通过量化冲击对189个经济体26个部门的经济影响,该研究发现,贸易集中化和地缘政治分化的综合效应加剧了冲击分布的不均衡。亚洲(如印度、中国)是积极冲击的主要受益者,通过产业链耦合实现了跨部门收益。欧洲(如德国、意大利)成为负面冲击的集中区,由于炼油技术被锁定在俄罗斯乌拉尔原油中,以及能源转型缓慢,一些地区持续受到负面影响。与此同时,地理位置关键的中小国家在冲击扩散中发挥着违反直觉的作用。与印度等大型经济体相比,突尼斯等战略枢纽国家对冲击的放大效应明显更高,起到了非线性冲击传导的放大作用。研究揭示了产业结构与地缘政治战略之间的协同效应导致面临冲击的国家间弹性差异,为全球能源产业协同治理提供政策指导。

Export controls and stock price fluctuations of affiliated companies: Empirical evidence from the US entity list against China 出口管制与关联公司股价波动:来自美国对华实体清单的经验证据

Due to the increasingly close supply chain, trade, and investment linkages among enterprises, external shocks not only directly impact target firms but also exert significant indirect effects on affiliated enterprises along the supply chain. This paper takes the US Entity List sanctions against Chinese entities as a case study to empirically examine the impact of export controls on the stock price volatility of Chinese affiliated enterprises. The results indicate that US export controls significantly exacerbate stock price volatility among Chinese affiliated enterprises, exerting a notable adverse impact. This effect is more pronounced for smaller-scale, highly liquid, low R&D intensity, and non-foreign-invested affiliated enterprises. Mechanism analysis reveals that three factors play critical roles in transmitting this impact: the risk-taking capacity of affiliated enterprises, supply chain concentration, and investor confidence. Specifically, higher risk-taking capacity and diversified supply chain structures mitigate the adverse effects, while lower risk-taking capacity and concentrated supply chains intensify them; investor confidence functions as a transmission channel amplifying the negative impacts. Further analysis using a Difference-in-Differences-in-Differences (DDD) model shows that amid intensified export controls, the stock price volatility of affiliated enterprises in the high-tech sector is more severe. For high-tech enterprises, government subsidies effectively mitigate these adverse effects; however, higher risk-taking capacity intensifies the negative impacts (whereas lower risk-taking capacity mitigates them), and the intensifying effect of supply chain concentration as well as the transmission effect of investor confidence become statistically insignificant. By integrating export controls and the stock price dynamics of affiliated enterprises into a unified analytical framework, this paper provides important micro-level evidence and policy implications for Chinese enterprises to effectively respond to the indirect impacts of external shocks, thereby facilitating capital market stability and high-quality economic development.
由于企业之间的供应链、贸易和投资联系日益紧密,外部冲击不仅直接影响目标企业,而且对供应链上的关联企业也产生了显著的间接影响。本文以美国实体清单制裁中国实体为例,实证检验出口管制对中国关联企业股价波动的影响。结果表明,美国出口管制显著加剧了中国关联企业的股价波动,产生了显著的不利影响。这种效应在规模较小、流动性高、研发强度低、非外商投资的关联企业中更为明显。机制分析表明,关联企业的风险承担能力、供应链集中度和投资者信心三个因素对这种影响的传导起着关键作用。具体而言,较高的风险承担能力和多元化的供应链结构缓解了不利影响,而较低的风险承担能力和集中化的供应链则加剧了不利影响;投资者信心是放大负面影响的传导渠道。利用差中差中的差(DDD)模型进一步分析表明,在出口管制加强的情况下,高新技术产业关联企业的股价波动更为严重。对高新技术企业而言,政府补贴有效缓解了这些不利影响;然而,较高的风险承担能力会加剧负面影响(而较低的风险承担能力会减轻负面影响),供应链集中度的强化效应和投资者信心的传导效应在统计上不显著。本文通过将出口管制与关联企业股价动态整合到一个统一的分析框架中,为中国企业有效应对外部冲击的间接影响,从而促进资本市场稳定和经济高质量发展提供了重要的微观证据和政策启示。

By integrating export controls and the stock price dynamics of affiliated enterprises into a unified analytical framework, this paper provides important micro-level evidence and policy implications for Chinese enterprises to effectively respond to the indirect impacts of external shocks, thereby facilitating capital market stability and high-quality economic development.</div></div>","PeriodicalId":54200,"journal":{"name":"Economic Analysis and Policy","volume":"89 ","pages":"Pages 965-985"},"PeriodicalIF":8.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the probability of default (PD) modeling has reached a great maturity in both academia and business, for the Italian case we demonstrate that banks’ available PD models would be misleading if today applied directly to Italian banks. We argue that what determines the PD of Italian banks, rather than the liquidity, are the return on assets (ROA), the financial leverage and the type of the bank. Furthermore, we demonstrate that the conventional approach dominates the more trendy machine learning (ML) and that model’s performance could be used as a supervisory tool for retrospective analysis of the bank’s position. This work stands out as the only study to consider state aid in defining bank default over the horizon period from 2010 to 2020, examining bank default in Italy across various types of banks, and employing both conventional and machine learning approaches, while also proposing an easy-to-handle three-variable model for predicting bank defaults.
尽管违约概率(PD)建模在学术界和商界都已经非常成熟,但对于意大利的案例,我们证明,如果今天直接应用于意大利的银行,银行现有的PD模型将具有误导性。我们认为,决定意大利银行PD的是资产回报率(ROA)、财务杠杆和银行类型,而不是流动性。此外,我们证明了传统方法在更流行的机器学习(ML)中占主导地位,并且该模型的性能可以用作对银行地位进行回顾性分析的监督工具。这项工作是唯一一项考虑国家援助来定义2010年至2020年期间银行违约的研究,研究了意大利不同类型银行的银行违约,并采用了传统和机器学习方法,同时还提出了一个易于处理的三变量模型来预测银行违约。

The research on the employment effect of the digital economy not only requires grasping the macro trends but also delving into the micro mechanisms. This study examines the impact of digital enterprise growth on labor employment in the supply chains of upstream and downstream enterprises, exploring the micro-logic of how the development of the digital industry affects employment levels. Our findings suggest that the growth of digital enterprises has a significant negative impact on the employment of their supply chain partners. Currently, the level of digital coordination within supply chains remains relatively low, which limits the job creation potential of digitalisation. Heterogeneity analysis reveals that this suppressive effect is particularly pronounced for digital enterprises in the eastern region, those in the digital technology application sector and technology-intensive enterprises. Conversely, digital enterprise growth in the central region appears to promote supply chain employment. Based on these findings, the paper proposes targeted policy recommendations.
研究数字经济的就业效应,既要把握宏观趋势,又要深入研究微观机制。本研究考察了数字化企业成长对上下游企业供应链劳动力就业的影响,探索数字化产业发展影响就业水平的微观逻辑。我们的研究结果表明,数字化企业的成长对其供应链合作伙伴的就业有显著的负面影响。目前,供应链内的数字化协调水平仍然相对较低,这限制了数字化创造就业的潜力。异质性分析表明,这种抑制作用在东部地区的数字企业、数字技术应用行业和技术密集型企业中尤为明显。相反,中部地区的数字企业增长似乎促进了供应链就业。基于这些发现,本文提出了有针对性的政策建议。

The impact of employment protection reform on the working conditions of fixed-term employees in Japan 就业保障改革对日本固定期限雇员工作条件的影响
IF 8.7 2区 经济学 Q1 ECONOMICS Pub Date : 2026-01-01 DOI: 10.1016/j.eap.2025.11.017

This paper examines the effects of Japan’s “5-year rule,” implemented in 2018, which mandates the conversion of fixed-term employees to permanent status upon their application after five consecutive years of employment. The analysis employs a difference-in-differences (DiD) approach combined with entropy balancing. Unlike other countries’ reforms, a distinctive feature of this reform is that it grants firms discretion over its implementation. Consequently, the reform significantly increased permanent employment conversions among middle-aged and older women with lower educational attainment, though it did not affect their transition to regular employment or wages. This effect is more pronounced for women in firms, industries, and occupations with conventionally high proportions of renewable contracts. Overall, while the reform enhances women’s employment stability, it entrenches gender and educational disparities in employment conditions, with stability differences persisting even among fixed-term employees based on conversion outcomes. Strengthening the complementary policies that address these issues is warranted.
本文考察了日本于2018年实施的“5年规定”的影响,该规定要求固定期限雇员在连续工作5年后申请转换为永久身份。分析采用差分法结合熵平衡。与其他国家的改革不同,这一改革的一个显著特征是,它赋予企业实施改革的自由裁量权。因此,这项改革大大增加了受教育程度较低的中老年妇女的永久就业转换,尽管它没有影响她们向正规就业或工资的过渡。这种影响在公司、行业和职业中更为明显,这些行业和职业通常具有较高的可再生合同比例。总体而言,虽然这项改革增强了女性就业的稳定性,但它巩固了就业条件中的性别和教育差异,即使是基于转换结果的固定期限员工之间的稳定性差异也仍然存在。有必要加强解决这些问题的补充政策。
