环境规制能否通过改善企业行为产生声誉治理效应，是评价环境政策微观经济 后果的重要维度。本文以 2012—2024 年沪深 A 股上市公司为研究样本，将 2018 年《中华 人民共和国环境保护税法》实施视为准自然实验，采用双重差分模型考察环境规制对企业声 誉风险的影响及其作用机制。研究发现：环境规制显著降低了企业声誉风险，经过平行趋势 检验、安慰剂检验、替换变量、排他性检验以及固定效应双重机器学习等一系列稳健性检验 后，该结论依然成立。机制分析表明，环境规制主要通过改善公司治理、提高信息披露质量 和提升 ESG 责任表现降低企业声誉风险。异质性分析发现，在媒体关注度较高、外部审计 监督较强、融资约束较低以及技术水平较高的企业中，环境规制的声誉治理效应更为显著。 进一步研究表明，声誉风险上升会提高企业信贷风险溢价，并对财务绩效产生一定的负向影 响，说明环境规制还能够通过缓释声誉风险产生融资改善效应和一定的经营改善效应。本文 从声誉风险视角拓展了环境规制微观经济后果的研究，为完善环境规制体系、加强企业环境 治理和促进企业可持续发展提供了经验证据。

I distinguish renminbi movements against the dollar from renminbi-relative repricing around U.S. tariff announcements. Across 26 policy groups, offshore renminbi (CNH) minus a fixed four-currency basket averages 35.077 aligned log basis points. Official reference rates corroborate the relative pattern; pre-event factor adjustment leaves a positive pooled own-CNH residual. Earlier disclosures change the later-period own-CNH sign, while early-to-late attenuation persists. Own-currency event-minus-lead contrasts remain imprecise, and macro-news and dependence screens weaken precision. The evidence supports an RMB-relative association, not a uniformly timed causal depreciation response or verified executable offshore prices.

The economic issue and development limitation has emerged during the middle-income stage, accumulated numerous hidden risks of 'irrational exuberance' and 'irrational depression' development and security becomes 'castles in the air', trapped in the predicament of economic hollowing-out and industrial hollowing-out.

以复杂性等同于不确定性的基本思想，提出了集群性复杂系统（以下简称复杂系统）的定义并推导出复杂系统的一对度量（C_d，C^±）方法，使得不同的复杂系统相互之间具有了可测可比性。 C_d是度量系统复杂性的一个指标，复杂系统的复杂性是由系统内的个体不确定性、能量（信息）大小、个体几何标度的综合变化所决定。“涌现”是复杂系统一个重要的特征现象，通过C_d可以度量系统呈现涌现的结果。 复杂度C^±是度量复杂系统平衡态的一个指标，度量复杂系统内各种力量对抗后形成的平衡状态，是描述复杂系统“自组织平衡”变化和波动的参量。 复杂系统度量属于基本参量，其原理和计算完全适用于模糊数学和灰色控制论这两门学科的模糊度和灰度的度量使用。

This paper examines the intricate relationship between China’s First Five-Year Plan (1953–1957) and the extensive Soviet aid that played a pivotal role in shaping early industrialization and economic policy in New China. Drawing upon both Chinese and Western literature, the study reviews the evolution of planned economy practices and Soviet economic assistance, analyzes the process of plan formulation and the formulation of key industrial targets, and assesses the quantitative and qualitative impact of Soviet aid on the successful implementation of the plan. By employing a multi-perspective literature review, archival research, and statistical data analysis, the paper identifies that Soviet technology, machinery, and planning expertise contributed significantly, estimates suggest that Soviet aid accounted for 30-40% of the capital inputs in key sectors and that this collaboration was instrumental in achieving heavy industry targets before the advent of reform and opening-up policies. Furthermore, the paper explores the subsequent divergence in the economic models of China and the Soviet Union, offering lessons on dependency, technology transfer, and the political dimensions of foreign aid. The findings not only contribute to our understanding of the early stages of China’s economic development but also shed light on the broader dynamics of Cold War-era international economic cooperation.

We identify choke points in global production networks as industries bridging flows across global value chains. These industries exhibit low substitutability: US firms exposed to Chinese choke points during the 2022 Covid-19 lockdowns experienced large and persistent sales declines. The Red Sea crisis demonstrates how negative shocks to water transport, a single choke point, propagate throughout the global network. This structural fragility is priced in global stock markets: firms in choke point industries earn annualized benchmark-adjusted returns exceeding 6%. The premium compensates for aggregate consumption risk, as downturns in choke point industries predict lower future US and global consumption growth.

This study constructs a new mispricing factor for the Chinese equity market. We propose two-, three-, and four-factor models that incorporate this factor alongside the market, size, and value factors. Our models, especially the two-factor version, consistently outperform the Fama and French models and perform as well as other leading models in explaining Chinese anomalies. This study advances asset pricing literature specific to China and offers a promising new framework for analyzing mispricing in emerging markets.

This study investigates the relationship between the number of stock concepts and future returns, as well as the economic mechanisms underlying this association. Using novel collected data, we find that stocks with a greater number of concepts earn significantly higher returns in the subsequent month, generating a six-factor adjusted annualized alpha of approximately 9.6% for a long-short portfolio. Although these stocks exhibit higher turnover, return volatility, and investor attention - features commonly associated with speculative concept-driven trading - an analysis of cross-listed AH twin stocks reveals that concept counts do not widen the AH premium. Moreover, the return premium persists for up to 15 months without significant reversal, whereas firms that engage in opportunistic concept-chasing exhibit pronounced long-run reversals, suggesting that the positive concept-return relation is not driven by speculative motives. The higher returns are primarily attributable to strong industrial policy support and sustained above-expectation operating performance. Firms with more concepts are more likely to receive government subsidies and deliver positive earnings surprises, effects that are amplified when their core concepts receive stronger national policy backing. In contrast, firms that pursue concepts lacking substantive business relevance are significantly less likely to obtain government subsidies and fail to achieve above-expectation growth. Regarding investor composition, institutional ownership of high-concept stocks increases modestly, while ownership by government-guided funds rises substantially - particularly for stocks whose core concepts are strongly supported by national industrial policies. Conversely, concept-chasing behavior by listed firms significantly reduces the ownership ratio of government-guided funds. Overall, our findings indicate that concept stocks in China’s capital market are not purely speculative but signal underlying national policies.

This paper investigates the sales seasonality premium (Gustavo et al., 2020) in the Chinese stock market. We document a significant sales seasonality premium in the cross section of stocks listed on Chinese market. A long-short strategy of buying low-sales stocks and shorting high-sales season stocks generate a monthly return of 0.84% with a Newey-West t statistic of 2.94. The return spreads between low-sales season stocks and high-sales season stocks are robust to well-known anomalies and are larger in magnitude among large-cap companies. We also find that the return spreads are more pronounced within industries with relatively fixed patterns in product demand. The sales seasonality premium in the Chinese stock market is found to be a combined result of investor rationality and irrationality.

This paper examines whether subjective macroeconomic expectations predict equity risk premia in China. Using professional macro forecasts from the Wind database over 2011- 2023, we construct a composite macroeconomic expectation index via PLS. We find that the index significantly and positively predicts future equity premia both in-sample and out-ofsample, implying a countercyclical equity premium. The predictive power is robust to a wide range of macro-financial controls and delivers economically meaningful gains in portfolio allocation. Further analysis shows that controlling for forecast errors does not attenuate predictability, and the subjective index largely subsumes the information in realized macro variables, suggesting that it captures forward-looking macroeconomic conditions rather than belief bias. Cross-sectional and long-horizon results reinforce this interpretation.
