These distance-based features are integrated into five machine learning models (CatBoost, Decision Tree, LightGBM, Support Vector Regression, and XGBoost) and evaluated against a linear regression benchmark across 840,000 experimental configurations. Our results demonstrate that distance-based features reduce both the mean absolute error and the root mean squared error relative to models trained on the original dataset alone, with normalized information distance exhibiting the most consistent improvements across targets and temporal configurations (<span><math><mrow><mi>p</mi><mo><</mo><mo>.</mo><mn>01</mn></mrow></math></span> in the majority of comparisons).

The findings reveal the following: First, developed economies are largely insulated from geopolitical shocks and exhibit a statistically significant risk aversion effect only in the low tail of the capital flow distribution, primarily preventing severe capital outflows during turbulent periods. Second, emerging and developing economies experience sharp declines in FDI and significant increases in FPI when geopolitical risks rise, reflecting speculative hot money seeking risk premiums rather than fundamentals driven capital. Third, a structural break analysis reveals that the 2008 financial crisis shifted global capital logics, causing mature economies to lose their immunity to FDI withdrawals while emerging markets increasingly attract FDI through supply chain restructuring. Fourth, heterogeneity analysis shows that higher FinTech penetration in emerging markets unexpectedly increases the negative effect of geopolitical risks on FDI by lowering withdrawal costs, whereas capital account restrictions mitigate these declines. These findings underscore how geopolitical fragmentation reshapes the composition of global finance, suppressing productive capital and fueling speculative volatility.</div></div>","PeriodicalId":48074,"journal":{"name":"Pacific-Basin Finance Journal","volume":"98 ","pages":"Article 103182"},"PeriodicalIF":5.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147797574","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}

This positive impact is more pronounced for firms exhibiting weaker profitability, tighter financing constraints, and lower supplier concentration, as well as for firms operating in regions with intensified fiscal pressure, less favorable business environments, and lower social trust. Mechanism analysis shows that the policy strengthens firms' bargaining power, reduces business risk, and improves firm reputation, thereby facilitating obtaining trade credit from their suppliers.

Firm value declines when firms replace, rather than supplement, incumbent directors, or when they comply closer to the regulatory deadline. A detailed analysis of individual directors shows that incoming female directors are, on average, younger, less experienced, and more likely to have non-business backgrounds compared to the departing directors.

While emerging economies' AI VC is vulnerable to frequent exogenous shocks, it exhibits a symbiotic relationship with cross-border AI VC over the long run. They reinforce and complement each other, but the dynamic impact of cross-border AI VC on domestic AI VC is more pronounced than the reverse in the short and medium run. Improved AI governance, enhanced AI-training dataset accessibility, and relaxed FDI restrictions in fabricated metal industries push the dynamic path of the response difference between non-China emerging economies and China toward zero.
