View corpus contextRapid digitalization has changed how firms organize production, manage information, and operate across national borders, raising growing interest in how digital technology shapes international expansion. While existing studies have discussed the role of digital transformation in firm performance, empirical evidence on how specific digital investments relate to firm internationalization remains limited, particularly in emerging-market contexts. Using panel data from Chinese A-share listed companies between 2015 and 2024, this study examines the relationship between artificial intelligence (AI) investment and firm internationalization. A fixed-effects regression model is employed to account for unobserved firm heterogeneity, and a series of robustness checks are conducted to ensure the stability of the results. Firm internationalization is measured by overseas income, while AI investment captures firms’ engagement in digital transformation. The empirical results show that firms with higher levels of AI investment tend to generate greater overseas income, indicating a positive association between digital investment and internationalization. This relationship remains stable across alternative model specifications and sample adjustments. In addition, firm size and profitability are positively related to internationalization, suggesting that resource availability and financial capacity support overseas expansion. By contrast, firms experiencing rapid growth in the domestic market are less active internationally, reflecting potential trade-offs in strategic focus. Overall, the findings provide firm-level empirical evidence on how digital investment relates to internationalization outcomes. The results also suggest that digital transformation is more likely to support international expansion when it is aligned with firms’ resources, technological capabilities, and organizational structures, rather than treated as an isolated technological initiative. Key words: digital transformation, international management, artificial intelligence, internationalization strategy, Chinese firms.
Summary
Main Finding
Firms that invest more in artificial intelligence (AI) tend to have higher overseas income — i.e., AI investment is positively associated with firm-level internationalization. This relationship is robust to alternative specifications. Firm size and profitability also positively predict internationalization, while rapid domestic growth is negatively associated with overseas activity, suggesting strategic trade-offs.
Key Points
- Sample: 3,790 Chinese A‑share listed firms (2015–2024), 37,883 firm‑year observations; financial, insurance, securities firms, ST/bankrupt firms excluded.
- Primary variables:
- Dependent: ln(Overseas Income) — firm internationalization measure.
- Main independent: ln(AI investment) — proxy for firm digital transformation.
- Controls: firm size (Ln_Size), leverage (LEV), return on equity (ROE), cash ratio, growth rate, Tobin’s Q, board size, board independence.
- Econometric approach: firm and year fixed‑effects panel regression (Hausman test strongly favored FE: χ²(9)=458.92, p<0.001).
- Main empirical results:
- Positive, statistically significant coefficient on ln(AI investment): higher AI spending associated with greater overseas income.
- Positive effects of firm size and profitability on internationalization.
- Negative association between domestic growth rate and overseas income (indicative of a resource/strategic trade‑off).
- Robustness: authors report the core result remains stable across alternative model specifications and sample adjustments (details not fully listed in the available excerpt).
- Conceptual takeaway: AI/digital investments support international expansion when integrated with firm resources, technological capabilities, and organizational structures — not as isolated tech projects.
Data & Methods
- Data source: CSMAR database covering Chinese A‑share listed firms, 2015–2024.
- Sample selection: excluded financial sector, firms under special treatment, bankrupt firms; final sample = 3,790 firms, 37,883 observations.
- Model specification:
- ln(Incomei,t) = α + β ln(AIi,t) + γ'Xi,t + μi + λt + εi,t
- μi = firm fixed effects; λt = year fixed effects.
- Identification strategy: within‑firm variation over time (fixed effects) controls for time‑invariant firm heterogeneity; time fixed effects control for macro shocks/trends.
- Diagnostic: Hausman test indicates fixed effects preferred over random effects.
- Limitations hinted/implicit: observational panel — potential endogeneity (e.g., reverse causality or omitted time‑varying confounders) not fully addressed in shown excerpt; measurement relies on disclosed AI investment as proxy for digital transformation.
Implications for AI Economics
- Allocation of AI capital: Evidence that AI investment correlates with measurable international market outcomes suggests a return channel for firms' AI spending beyond domestic productivity gains. AI economics should therefore incorporate international revenue effects when modeling firm‑level returns to digital capital.
- Complementarities and absorptive capacity: Positive effects depend on firm size and profitability, implying complementarities between AI and organizational/financial resources. Models of AI adoption should account for heterogeneity in firm capabilities and the need for complementary investments (HR, governance, platforms).
- Strategic trade‑offs: The negative link between domestic growth and overseas income highlights allocation choices — investing to dominate a home market may come at the expense of international expansion. Economists should model how AI investment interacts with strategic focus and market selection.
- Policy: For emerging‑market contexts, supporting AI capacity building (financing, talent, governance) can have spillovers to firms’ international competitiveness. Policy design should consider enabling complementary organizational change, not only subsidizing hardware/software purchases.
- Research directions: Future AI economics work should seek causal identification (e.g., instrumental variables, policy shocks), unpack mechanisms (marketing reach, supply‑chain optimization, decision support), and investigate heterogeneity by industry, ownership type, and target markets.
Assessment
Paper Typecorrelational
Evidence Strengthlow — Findings are based on observational panel associations: firm fixed effects remove time-invariant confounders but cannot rule out time-varying omitted variables, reverse causality (internationalization driving AI investment), or measurement error in the AI-investment proxy, so causal claims are weak.
Methods Rigormedium — The study uses a standard and appropriate panel approach (firm fixed effects) and reports robustness checks, which strengthens internal validity relative to cross-sections; however, the absence of an exogenous source of variation (IV, diff-in-diff, regression discontinuity) or detailed strategies for addressing endogeneity and measurement error limits methodological rigor for causal inference.
SampleFirm-year panel of Chinese A-share listed companies, 2015–2024; dependent variable: overseas income (measure of internationalization); independent variable: firms' AI/digital investment engagement (proxied by firm-reported digital/AI investment measures); covariates include firm size, profitability, domestic growth and other firm controls; analysis focuses on listed firms across sectors in mainland China.
Themesadoption org_design
IdentificationPanel fixed-effects regression exploiting within-firm variation in measured AI investment over 2015–2024, with firm-level controls and robustness checks; no exogenous instrument, natural experiment, or explicit causal design is reported.
GeneralizabilityRestricted to publicly listed Chinese A-share firms—may not generalize to private firms, SMEs, or non-listed firms, China-specific institutional, regulatory, and market context may limit applicability to other countries, Outcome (overseas income) captures one dimension of internationalization and may omit exports, foreign affiliates, or strategic partnerships, AI investment measured via firm reports/proxies may not capture true technological capability or usage intensity, Study period (2015–2024) includes rapid digitalization in China; effects may differ in earlier/later periods or different stages of AI adoption
