Abstract :
As Artificial Intelligence (AI) technology advances rapidly, its role in promoting regional energy transformation is becoming increasingly apparent. This paper utilizes regional-level panel data from China, covering the period from 2011 to 2021, to systematically assess the impact of AI development on energy transformation. Using econometric models, including fixed-effects and instrumental variable regressions, the study reveals that an increase in AI enterprises within a region significantly reduces energy consumption per unit of GDP, thereby accelerating regional energy transition. The analysis identifies two primary channels through which AI exerts this effect: by facilitating the upgrading of the regional industrial structure and by promoting the growth of the digital economy. The findings also show that the impact of AI is more pronounced in highly urbanized regions, particularly in the Yangtze River Economic Belt. Additionally, the results highlight that AI-driven reductions in energy consumption are largely achieved through improved efficiency in coal and electricity usage, addressing key structural issues in China's energy landscape.

Abstract :
In this paper, we utilize panel data encompassing 44 emerging market countries from 1996 to 2020 to investigate the impact of openness on financial development and rethink the interrelationship between trade openness and financial openness. Our findings indicate that openness contributes to the promotion of financial development. Furthermore, this paper extends and refines the classification of open relationships by considering three distinct types of policymakers: prudent, radical, and discretionary. Through this categorization, we shed light on the ambiguity of the marginal effects of trade and financial opening policies.

Abstract :
The low-carbon city pilot policy (LCCPP) is a key initiative designed to promote low-carbon development and sustainable economic growth. To maximize its environmental and economic benefits, it is essential to conduct a comprehensive evaluation of the policy's influence on the transformation of the low-carbon economy (TLCE). This paper spans the period from 2003 to 2021, analyzing a sample of 281 Chinese cities at the prefecture level or higher. First, the research employs the super-efficient EBM-GML model, incorporating non-desired outputs, to measure the TLCE. Second, the progressive difference-in-differences model integrates the TLCE into the assessment framework of the LCCPP, allowing for an empirical analysis of its effects on the transformation. Third, a heterogeneity analysis is conducted from various perspectives, including the "Hu Huanyong line, " coastal and inland cities, and environmental protection priority cities. Finally, the paper investigates the linear mechanisms of the LCCPP on the TLCE across three dimensions: environment, economy, and technology. The environmental dimension reflects urban ecological resilience, the economic dimension pertains to the development level of the digital economy, and the technological dimension relates to scientific and technological innovation activity. Additionally, the paper examines the nonlinear mechanisms through which the LCCPP affects the TLCE, focusing on environmental regulation and factor endowment. The results indicate that: 1) The LCCPP significantly facilitates the TLCE in the experimental areas, with findings remaining robust across various tests, including parallel trend test, SDID, a test of heterogeneity in treatment effects, and PSM-DID. 2) Heterogeneity analysis shows the policy's impact is stronger in cities south of the "Hu Huanyong line, " as well as in coastal cities and environmental protection priority cities. 3) Linear mechanism analysis indicates that urban ecological resilience, the development level of the digital economy, and scientific and technological innovation activity serve as partial intermediaries in the TLCE influenced by the LCCPP. 4) Nonlinear mechanism analysis indicates that environmental regulation and factor endowment influence TLCE in nonlinear ways, with effects varying across different threshold stages. Specifically, when environmental regulation and factor endowment are at varying developmental stages, the LCCPP effect tends to follow a "first suppressed, then elevated" trend. Based on these findings, the paper recommends expanding the scope of the LCCPP and sharing experiences in low-carbon development to support achieving the "dual-carbon" goal within China's innovation strategy.

Abstract :
This study investigates how financial institution agglomeration affects labor allocation efficiency in non-financial firms listed on China's A-share markets, within a context of expanded government debt and relaxed local debt financing controls. Results show that such agglomeration significantly improves labor efficiency, mainly by easing financing constraints. The positive impact is stronger in non-state-owned and manufacturing firms.

Abstract :
汇率政策作为一国货币当局进行宏观调控的一个集中体现,已经成为中美两国经贸领域角力的核心.美国倚赖美元优势地位压制中国在全球价值链上的崛起.因此,运用汇率政策摆脱美元霸权掣肘、攀升价值链成为中国构建新发展格局的关键.本文结合全球价值链框架下的汇率不完全传递特征,通过构建两国汇率政策博弈的一般性模型,剖析2008年全球金融危机和2020年疫情后中美汇率政策博弈的典型案例,验证发现,面对美国奉行保护主义的"胁迫"博弈,得益于扭转价值链分工地位的低端锁定局面,中国实现了从被动向主动应对的政策转变,却囿于美国内倾化的利益诉求而无法扩大各国的利益汇合点,导致不能达成以利益融合为原则的帕累托均衡.为了破解该困境,本文进一步以全球价值链的区域化重构趋势为着力点,论证构建以中国为主导的区域价值链,形成与区域内国家的博弈对称解是共赢选择.

Abstract :
基于2013—2022年123家商业银行和宏观经济相关数据,运用加权无标度网络模型测算商业银行的系统性风险水平,并利用非平衡面板模型实证金融科技对商业银行系统性风险的影响。研究发现,金融科技的发展从整体上有助于商业银行的系统性风险的降低,但早期金融科技发展对商业银行系统性风险的影响并不显著,成熟期的金融科技能够降低系统重要性银行和农村商业银行的系统性风险。此外,金融科技通过信息渠道降低了系统重要性银行的系统性风险,却通过内部控制渠道加剧了除系统重要性银行和农村商业银行以外其他商业银行的系统性风险。但成熟期的金融科技有能力通过成本渠道缓释除农村商业银行以外的商业银行系统性风险。据此,本文提出相应的政策建议。

Abstract :
在中美贸易摩擦不断和中国扩大对外开放的背景下,马歇尔-勒纳条件作为汇率变动与贸易关系的重要理论,对经济现实具有极其重要的指导价值.通过将人民币实际有效汇率分解为人民币对美元实际有效汇率和美元实际有效汇率的乘积形式,推演国际收支弹性分析法,将美国对中国出口和美元有效汇率对中美实际汇率的弹性作为重要参数,得到修正的马歇尔-勒纳条件.为了验证结论的合理性,将汇率和贸易福利进行有机结合,采用异质性企业一般均衡框架对分行业贸易福利进行估计,深入分析中美汇率波动对我国贸易福利的影响.结果发现,修正的马歇尔-勒纳条件成立,汇率与贸易福利呈现较为明显的正相关关系.基于此提出相应的政策建议.
