Exploring the intrinsic link between the intensity of intellectual property protection and the optimization of regional technological innovation structure from the perspective of economic complexity theory. Using panel data and employing the dual fixed effects estimation method, we empirically examine the impact of intellectual property protection strength on innovation factors, the innovation environment, and innovation output. Our study finds that intellectual property protection has a positive incentive effect on knowledge acquisition, knowledge creation, the innovation environment, and substantive innovation, while it inhibits non-substantive innovation. Strong intellectual property protection effectively promotes the optimization of innovation factors, the innovation environment, and innovation output structures, thereby driving the optimization of the regional technological innovation structure. In terms of impact magnitude, the order from high to low is: knowledge creation, substantive innovation, innovation environment, knowledge acquisition, and non-substantive innovation. The "optimal intensity" of intellectual property protection significantly promotes the optimization of the regional technological innovation structure, whereas excessively strong or weak intellectual property protection hinders this optimization. Implementing a strategy of innovation-driven development requires further reform and improvement of the national intellectual property protection system to establish the optimal intensity of protection and promote the optimization of the regional technological innovation structure.
从经济复杂性理论视角探究知识产权保护强度与区域技术创新结构优化之间的内在联系。利用面板数据并采用双重固定效应估计方法，我们实证检验了知识产权保护强度对创新要素、创新环境和创新产出的影响。我们的研究发现，知识产权保护对知识获取、知识创造、创新环境和实质性创新具有正向激励作用，而对非实质性创新具有抑制作用。强有力的知识产权保护有效促进了创新要素、创新环境和创新产出结构的优化，从而推动区域技术创新结构的优化。在影响程度方面，从高到低的顺序为：知识创造、实质性创新、创新环境、知识获取和非实质性创新。知识产权保护的“最优强度”显著促进区域技术创新结构的优化，而过度强或弱的知识产权保护则会阻碍这种优化。实施创新驱动发展战略需要进一步改革和完善国家知识产权保护制度，以确立最优保护强度，促进区域技术创新结构的优化。
