The paper empirically examines the impact of the technological capabilities on export performance.Results suggest that technical intensity of human resource has adverse impact on export performance;RD has no impact on export performance,while the interaction of IT with technical human resource and with RD has positive impact on export performance.The paper reiteratively reflects that the technological competitive advantages of China manufacturing firms are weak.The paper suggests that our outward firms should pay more attention to the infrastructures of information technology at the process of internationalization.
