This paper develops a dynamic Agent Based Model to study the role of cross-border data flows for the joint uptake of artificial intelligence enabled software in manufacturing and engineering. The model features two technology-related business models: engineering as a face-to-face consultancy service, and engineering as a software licensing service. Engineering agents harvest data from their software clients in the home country and abroad and use the data for quality assurance and software updates. We compare scenarios along two dimensions: (i) harvesting data from own clients only versus from open data repositories, (ii) the strength of competition measured by the probability that a contract will be extended by another period. We find that restrictions on cross-border data flows slow down the speed of adoption considerably, particularly in small countries. The simulations generate an S-shaped technology uptake path for manufacturers and a U-shaped relationship between competition and technology uptake in engineering. Interestingly, cross-border data flows flatten the U.
本文开发了一个动态的基于Agent的模型来研究跨界数据流在制造和工程中联合采用人工智能软件中的作用。该模式以两种与技术相关的商业模式为特色:作为面对面咨询服务的工程,以及作为软件许可服务的工程。工程代理从国内外的软件客户那里收集数据,并将这些数据用于质量保证和软件更新。我们从两个方面比较了各种情况:(i)只从自己的客户那里收集数据,而不是从开放的数据存储库中收集数据;(ii)通过合同将被延长一段时间的可能性来衡量的竞争强度。我们发现,对跨境数据流动的限制大大减缓了采用的速度,特别是在小国。仿真结果表明,制造业的技术吸收路径为s型,竞争与工程技术吸收之间呈u型关系。有趣的是,跨境数据流使美国经济趋于平缓。

Drawing on the NEBIC framework, this study constructs a supply chain network using data on China’s A-share listed firms from 2010 to 2021. It examines how the digital transformation of focal firms affects the supply chain carbon emissions. IV-2SLS, DID and System-GMM are used to deal with endogeneity. The analysis reveals that digital transformation significantly reduces supply chain carbon emissions through environmental information spillovers and green innovation spillovers. Moreover, the effects are strengthened by greater environmental regulatory intensity and executives’ environmental awareness. Heterogeneity analysis indicates that the reduction impact of digital transformation is more pronounced in the eastern and western regions, and is stronger among high-tech and low-pollution industries. Furthermore, the effect is greater for upstream suppliers than for downstream customers. These findings underscore the broader environmental benefits of digital transformation from a network perspective and offer theoretical support for both government policy design and corporate supply chain decarbonization strategies.
本研究借鉴NEBIC框架,利用2010 - 2021年中国a股上市公司的数据构建了供应链网络。它考察了重点企业的数字化转型如何影响供应链碳排放。采用IV-2SLS、DID和System-GMM处理内生性问题。分析表明,数字化转型通过环境信息溢出效应和绿色创新溢出效应显著降低供应链碳排放。此外,更大的环境监管力度和高管的环境意识会加强这种效应。异质性分析表明,数字化转型的减排效应在东部和西部地区更为明显,在高技术和低污染产业中更为明显。此外,上游供应商的影响大于下游客户。这些发现从网络的角度强调了数字化转型的更广泛的环境效益,并为政府政策设计和企业供应链脱碳战略提供了理论支持。

Optimizing carbon responsibility allocation in the steel supply chain: A cradle-to-cradle life cycle assessment approach 优化钢铁供应链中的碳责任分配:一个从摇篮到摇篮的生命周期评估方法
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-09-22 DOI: 10.1016/j.strueco.2025.09.006

This study addresses the challenge of incentivizing carbon reductions in supply chains under carbon pricing mechanisms. Focusing on upstream raw materials, we propose a cradle-to-cradle life cycle assessment (LCA)-based carbon accounting model and a cooperative game model to optimize the fair allocation of carbon responsibility across a multi-level, multi-agent supply chain. Using a steel-construction supply chain case, we validate the model and uncover key insights: 1) High-performance products, with high production emissions but lower use-phase emissions, face unfair responsibility allocation when only production-stage emissions are considered; 2) Focusing on production-stage reductions leads to emission responsibility transfer from downstream to upstream and from larger to smaller companies; 3) Factors such as material-saving rates, product lifespan, and recycling have a greater impact on life cycle emissions than production-stage reductions alone. Based on these findings, we recommend enhancing the carbon labeling system and optimizing responsibility allocation to balance production and use-phase emissions.
本研究解决了在碳定价机制下激励供应链碳减排的挑战。针对上游原材料,本文提出了基于从摇篮到摇篮生命周期评估(LCA)的碳会计模型和合作博弈模型,以优化多层次、多主体供应链的碳责任公平分配。以钢结构供应链为例,我们验证了模型并揭示了关键见解:1)仅考虑生产阶段排放时,生产阶段排放高但使用阶段排放低的高性能产品面临不公平的责任分配;2)注重生产阶段的减排导致排放责任从下游向上游、从大型企业向小型企业转移;3)材料节约率、产品寿命和回收等因素对生命周期排放的影响大于生产阶段减排。基于这些发现,我们建议加强碳标签制度,优化责任分配,以平衡生产和使用阶段的排放。

The rise of the middle class and the pattern of consumption imports in Latin America 拉丁美洲中产阶级的崛起与消费进口模式
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-09-14 DOI: 10.1016/j.strueco.2025.08.016

This paper examines the relationship between the middle class and the pattern of consumption imports in fifteen Latin American economies over the period 1996–2019, which includes the latest commodity boom. The consumption patterns of the middle class, which are likely to be different from those of lower classes, could be reflected in the imports in the case of countries with little diversified productive structures, such as those of Latin America. In the context of highly unequal countries, the middle class may not only consume according to its own preferences, but may also be driven by emulation and status motives. My results show that the middle class has become the main income group driving both aggregate consumption imports and imports disaggregated by product type, including luxury imports. The estimated coefficients are particularly large for the lower-middle class and during the period of the commodity boom, when this income group expanded most rapidly. This finding points to a significant role of the middle class as a determinant of consumption imports and their composition, with implications for the region’s fragile balance of payments dynamics.
本文研究了1996年至2019年期间15个拉丁美洲经济体的中产阶级与消费进口模式之间的关系,其中包括最近的大宗商品繁荣。中产阶级的消费模式可能不同于下层阶级的消费模式,在生产结构很少多样化的国家,例如拉丁美洲的国家,这种消费模式可以反映在进口上。在高度不平等的国家背景下,中产阶级不仅可能根据自己的喜好消费,还可能受到模仿和地位动机的驱动。我的研究结果表明,中产阶级已经成为推动总消费进口和按产品类型分类进口(包括奢侈品进口)的主要收入群体。估计的系数对于中下阶层和在商品繁荣时期尤其大,这一收入群体扩张最为迅速。这一发现表明,中产阶级作为消费进口及其构成的决定因素发挥着重要作用,这对该地区脆弱的国际收支动态产生了影响。

Habit formation under stress: How COVID-19 reshaped Chinese consumer behavior — short-term disruptions and long-term behavioral entrenchment 压力下的习惯形成:新冠肺炎如何重塑中国消费者行为——短期破坏和长期行为巩固
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-11-06 DOI: 10.1016/j.strueco.2025.11.003

During the COVID-19 pandemic, external shocks like social distancing, supply chain disruptions, and economic uncertainty reshaped consumption patterns, accelerating the shift from offline dependence toward digital, contactless, and precautionary savings-oriented habits. However, it remains unclear whether these changes represent temporary adaptations or persistent structural transformations. Using panel data on urban and rural household consumption across 115 prefecture-level cities from 2016 to 2022, supplemented by transaction records from the Taobao platform, this study employs difference-in-differences (DID) and regression discontinuity design (RDD) methodologies to identify the causal impact of the pandemic. By controlling for per capita disposable income, levels of digital economic development, and other confounding factors, we isolate the net effect of COVID-19 and evaluate both its short- and long-term influences. The analysis shows the pandemic reduced consumption across urban and rural residents, with gradual recovery. Urban areas experienced larger declines than rural regions, demonstrating a dichotomy between “structural contraction in cities versus adaptive recovery in rural areas”. Structurally, the pandemic induced a dual short-term phenomenon: consumption downgrading (a shift toward essential goods under survival pressure, reflected in a rising Engel coefficient) coexisted with consumption upgrading (a shift toward higher-quality, green products, and digital services driven by health and ecological awareness), while the long-term trajectory pointed toward upgrading. Offline consumption gave way to online platforms, with digital spending normalizing from emergency shifts. These findings reveal the shift from reactive reaction to habit formation, informing retail channel optimization, unlocking rural demand, and advancing green–digital integration to support high-quality post-pandemic economic recovery efforts.
在2019冠状病毒肺炎大流行期间,保持社交距离、供应链中断和经济不确定性等外部冲击重塑了消费模式,加速了人们从依赖线下向数字化、非接触式和预防性储蓄习惯的转变。然而,目前尚不清楚这些变化是暂时的适应还是持续的结构转变。本研究利用2016年至2022年115个地级市的城乡家庭消费面板数据,并辅以淘宝平台的交易记录,采用差分法(DID)和回归不连续设计(RDD)方法来确定疫情的因果影响。通过控制人均可支配收入、数字经济发展水平和其他混杂因素,我们隔离了COVID-19的净影响,并评估了其短期和长期影响。分析显示,疫情减少了城乡居民的消费,并逐渐恢复。城市地区的下降幅度大于农村地区,显示出“城市结构性收缩与农村地区适应性复苏”之间的二分法。从结构上看,疫情引发了一种双重短期现象:消费降级(在生存压力下向必需品转移,体现在恩格尔系数上升)与消费升级(在健康和生态意识驱动下向更高质量、绿色产品和数字服务转移)并存,而长期轨迹则指向升级。线下消费让位于线上平台,数字消费从紧急轮班常态化。这些发现揭示了从被动反应到习惯形成的转变,为零售渠道优化提供了信息,释放了农村需求,并推进了绿色数字一体化,以支持高质量的大流行后经济复苏努力。

The green development coordination of land economy (LE) and marine economy (ME) is an inevitable choice to respond to the requirements of sustainable development. This paper measures the level of LE and ME green development synergy in China from 2010 to 2023, and further analyzes the regional differences and convergence characteristics in coordination by using Dagum Gini coefficient method and convergence model. The research shows that LE and ME green development synergy level in all regions has risen to good coordination. The main source of the difference of LE and ME green development synergy has changed from hypervariation density to inter-regional differences, and the internal difference of southern marine economic circle is the largest. Only the northern marine economic circle exists σ convergence in stage 1, and it maintains stable β convergence with coastal area, which is affected by different factors in different periods. Therefore, make policy recommendations.

Heterogeneous effects of frontier technology adoption on economic growth in Africa 前沿技术采用对非洲经济增长的异质效应
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-09-16 DOI: 10.1016/j.strueco.2025.09.004

The Fourth Industrial Revolution is ushering economies into a new era of technological transition, driven primarily by frontier technologies. While the adoption of these technologies is growing rapidly in the Global South, empirical evidence concerning their economic impacts in Africa are hard to find. This study advances the innovation and growth literature in this regard by analysing macro data from 39 African countries. Findings from quantile regression reveal that frontier technology adoption (FTR) has a modest positive effect on growth. Second, democracy amplifies the impact of FTR, but only at higher levels of egalitarianism. Third, although FTR is growth-enhancing across all growth quantiles, its impact diminishes from the 1st to the 9th. However, in the presence of egalitarian democracy, FTR significantly boosts growth from the 1st to the 9th quantiles. We conclude that progress in egalitarianism and investment in frontier technology readiness are essential for sustained economic growth in Africa.
第四次工业革命正在引领各经济体进入以前沿技术为主要驱动力的技术转型新时代。虽然这些技术的采用在全球南方迅速增长,但很难找到有关其对非洲经济影响的经验证据。本研究通过分析39个非洲国家的宏观数据,推进了这方面的创新和增长文献。分位数回归的结果表明,前沿技术采用(FTR)对经济增长具有适度的正向影响。其次,民主放大了FTR的影响,但只在更高的平均主义水平上。第三,尽管FTR在所有增长分位数中都能促进增长,但其影响从1号到9号逐渐减弱。然而,在平等民主存在的情况下,FTR显著促进了第1至第9分位数的增长。我们的结论是,平等主义的进步和前沿技术准备方面的投资对非洲的持续经济增长至关重要。

Innovation and industry growth under private and public ownership: non-creative destruction versus welfare maximisation 公私所有制下的创新与产业增长:非创造性破坏vs福利最大化
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-08-26 DOI: 10.1016/j.strueco.2025.08.010

We analyse the impact of ownership, market structure, and quality of governance on sustainable industry growth as driven by process innovations generated by salaried agents under asymmetric information. The agent faces uncertainty because of performance-related pay and random punishments, which can be imposed by the employer (as arguably in the case of Nokia’s demise as a producer of mobile phones) or by external forces. Intermediate concentration yields the highest growth when firms maximise profits, but innovation costs increase with the market size. This can lead to monopolisation, and hence to non-creative destruction. A welfare-maximising public monopoly outperforms the oligopoly, but not necessarily under bad governance. An oligopoly can reach reasonable growth, but only under stringent conditions if the discount rate is low.

我们分析了在信息不对称条件下,受薪代理人产生的流程创新驱动下,所有权、市场结构和治理质量对可持续行业增长的影响。代理人面临着不确定性,因为与绩效挂钩的薪酬和随机惩罚,这些惩罚可能是由雇主施加的(正如诺基亚作为手机生产商的消亡案例中所争论的那样),也可能是由外部力量施加的。当企业利润最大化时,中间集中度产生最高的增长,但创新成本随着市场规模的增加而增加。这可能导致垄断,从而导致非创造性破坏。福利最大化的公共垄断优于寡头垄断,但在治理不善的情况下未必如此。寡头垄断可以达到合理的增长,但只有在贴现率较低的严格条件下。到那时,公有制可能是一个有吸引力的选择,但改善治理、确保体面工作条件、工作保障和长期主义的干预措施可能是必要的。(# 149)

Can industrial–financial integration boost corporate TFP? Evidence from listed corporations holding financial institutions’ shares 产融融合能提高企业全要素生产率吗?来自持有金融机构股份的上市公司的证据
IF 5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-05-22 DOI: 10.1016/j.strueco.2025.05.023

Enhancing total factor productivity (TFP) is critical for driving high-quality economic development in China. This study examines whether industrial–financial integration—a key strategy for advancing large corporate conglomerates—contributes to boosting corporate TFP. Drawing on analysis of panel data from non-financial corporations listed on China’s A-share market (2008–2023), this study demonstrates three main empirical findings. First, industrial–financial integration positively influences corporate TFP, particularly benefiting corporations in the maturity stage, as opposed to those in the growth or decline stages. Second, industrial–financial integration enhances corporate TFP through three primary channels: compensation incentive, innovation input, and operational capacity. Third, the positive effects are more pronounced for corporations with low financing constraints, those in highly competitive or non-high-tech industries, and those located in provinces with advanced financial development. This study’s findings provide a theoretical framework guiding policy development and corporate strategies aiming to leverage financial mechanisms in advancing the real economy.
提高全要素生产率是推动中国经济高质量发展的关键。本研究考察了产业金融一体化是否有助于提高企业全要素生产率,这是推动大型企业集团发展的关键战略。通过对中国a股非金融类上市公司2008-2023年面板数据的分析,本研究得出了三个主要实证结果。首先,产融融合对企业全要素生产率有正向影响,成熟期企业比成长期或衰退期企业受益更大。二是产融融合通过薪酬激励、创新投入和经营能力三个主要渠道提升企业全要素生产率。第三,对于融资约束程度较低的企业、处于高竞争力产业或非高技术产业的企业以及位于金融发达省份的企业,积极效应更为明显。本研究的发现为旨在利用金融机制促进实体经济发展的政策制定和企业战略提供了一个理论框架。

Patterns of subordination in the Global South between natural resources, foreign ownership and financial inflows 全球南方国家在自然资源、外国所有权和资金流入之间的从属关系
IF 5.5 2区 经济学 Q1 ECONOMICS Pub Date : 2025-12-01 Epub Date: 2025-09-04 DOI: 10.1016/j.strueco.2025.09.001

Peru and Kazakhstan have often been presented as success stories—respectively, in Latin America and Central Asia—due to their sustained economic growth since the early 2000s. Despite their distinct histories, geographies, and cultural contexts, both countries exhibit comparable economic features: a heavy reliance on natural resource exports, significant foreign ownership in strategic sectors, and persistent dependence on external financial inflows. These shared characteristics raise concerns about a common pattern of dependency and subordination. While the 2003–2014 commodity supercycle enabled both countries to reduce poverty and transition into upper-middle-income status, this growth was primarily driven by extractive sectors and fuelled by foreign capital. Beneath this apparent success lies a more troubling reality: structural current account deficits, driven by negative primary income balances despite strong trade surpluses. These deficits were increasingly financed through pro-market policies aimed at attracting foreign direct investment, particularly in copper extraction in Peru and oil in Kazakhstan. Although commodity prices have experienced partial revivals, long-term sustainability remains questionable—especially given rising social unrest and mounting geopolitical tensions. This paper explores the financial underpinnings of this subordination by analysing balance of payments dynamics and international investment position statistics for both countries and further contrasting it with Mexico as a third country. In doing so, it critically assesses the viability of development strategies based on natural resource extraction and foreign capital inflows, situating the analysis within broader geopolitical and historical frameworks.
由于秘鲁和哈萨克斯坦自21世纪初以来的持续经济增长,它们经常被视为拉美和中亚的成功案例。尽管两国的历史、地理和文化背景不同,但两国都表现出类似的经济特征:严重依赖自然资源出口,战略部门的大量外资所有权,以及对外部资金流入的持续依赖。这些共同的特征引起了人们对依赖和从属的共同模式的关注。虽然2003-2014年的大宗商品超级周期使两国得以减少贫困并向中高收入国家过渡,但这种增长主要是由采掘部门推动的,并得到了外国资本的推动。在这种表面上的成功背后,隐藏着一个更令人不安的现实:结构性经常账户赤字,尽管贸易顺差强劲,但主要收入余额为负。这些赤字越来越多地通过旨在吸引外国直接投资的亲市场政策来提供资金,特别是在秘鲁的铜矿开采和哈萨克斯坦的石油开采方面。尽管大宗商品价格出现了部分回升,但长期可持续性仍存在问题——尤其是在社会动荡加剧和地缘政治紧张局势加剧的情况下。本文通过分析两国的国际收支动态和国际投资头寸统计数据,并进一步将其与作为第三国的墨西哥进行对比,探讨了这种从属关系的金融基础。在此过程中,它批判性地评估了以自然资源开采和外国资本流入为基础的发展战略的可行性,并将分析置于更广泛的地缘政治和历史框架内。
