本文深入分析了中外合资企业的发展变迁路径，着重探讨了其科技自主创新与不同发展演化路径之间的关系。通过对广州宝洁、娃哈哈和奇瑞捷豹路虎等典型案例的分析，研究发现：首先，中外合资企业数量虽逐渐增加，但在总企业数中的比例呈下降趋势。尽管独资企业数量增加，但大多数合资企业仍选择继续保持合资模式。其次，在合资过程中，外方企业常采用技术控制策略以维护技术优势和限制中方企业的竞争力，同时也干扰了技术外溢效应。第三，中外合资企业科技自主创新能力仍然较弱，依赖外方技术的现象普遍存在。合资企业应增强自主创新能力，减少对外国技术和资源的依赖，以实现独立发展。总的来说，中外合资企业在相对均衡的控制权下，通过合资双方优势资源的互补与推动和增强自身的自主创新能力，才能主导自身发展前景并且实现长远稳定发展。

This paper conducts an in-depth analysis of the developmental trajectories of Sino-foreign joint ventures, focusing on the relationship between their technological self-innovation and different evolutionary paths. Through case studies of Procter & Gamble in Guangzhou, Wahaha, and Chery Jaguar Land Rover, the research reveals several key findings. Firstly, while the number of Sino-foreign joint ventures has gradually increased, their proportion within the total number of enterprises has declined. Despite the rise in the number of wholly-owned ventures, most joint ventures continue to maintain their cooperative mode. Secondly, during the joint venture process, foreign enterprises often employ technology control strategies to maintain their technological advantage and limit the competitiveness of Chinese enterprises, which also disrupts the technology spillover effect. Thirdly, the technological self-innovation capability of Sino-foreign joint ventures remains weak, with a prevalent reliance on foreign technology. Joint ventures should enhance their independent innovation capabilities and reduce dependence on foreign technology and resources to achieve independent development. Overall, Sino-foreign joint ventures, under relatively balanced control, can dominate their development prospects and achieve long-term stable development through the complementary advantages of both parties and by strengthening their independent innovation capabilities.
