The sustainable development of the energy industry heavily relies on the efficient operation of cross-regional investment networks among energy enterprises. However, under multiple risk shocks such as extreme weather, market volatility, and policy uncertainty, issues like "node failures" and "disconnected links" in these networks may lead to systemic risks, including worsening curtailment of wind and solar power and regional development imbalances. Against this backdrop, enhancing network resilience has become pivotal in addressing the challenges of energy transition. This study utilizes cross-regional investment data from China's A-share listed energy companies (2010-2023) to construct a nationwide energy enterprise investment network spanning 31 provinces. First, it systematically examines the synergistic effects of network resilience on economic, environmental, and welfare performance. Second, leveraging the SHAP model, it quantifies the contribution and nonlinear interactions of influencing factors. Finally, stress-test simulations of node and link failure scenarios are conducted to propose differentiated optimization pathways for "targeted network reinforcement. "Findings reveal that: (1) The resilience of cross-regional energy investment networks has steadily improved, with notable growth in absorptive and restorative capacities, though regional disparities persist (higher in eastern vs. western China); (2) Enhanced network resilience significantly drives economic performance while demonstrating positive trends for environmental and welfare outcomes, highlighting its multidimensional synergies; (3) Local fiscal expenditure, foreign investment, the number of industrial enterprises above designated size, and infrastructure are key determinants, with multifactor interactions exhibiting nonlinear dynamics; (4) Critical node failures trigger precipitous declines in network resilience, whereas a "shortboard remediation" strategy can efficiently bolster systemic robustness. These findings provide both theoretical foundations and actionable pathways for advancing energy network resilience and sustainable development.
