Science parks and innovation policies have a major mission in driving innovative resources and nurturing emerging industries, while the government-academia-industry collaborations and the establishment of an ecosystem are essentials. To investigate the key driving forces for sustainable development of the collaborative ecosystem, this article evaluates the technological innovations and the ecosystem of Science Parks in Shanghai based on historical data obtained from Shanghai Zhangjiang Science Park (Zhangjiang Park in short). Systems thinking and causal loop analysis are adopted to explore the structure of the collaborative ecosystem and reflections of the policy impact on the science park. The role of the government in science parks and innovation ecosystems is identified with systems mapping and empirical study. The economic impact of Zhangjiang Park policies and the performance of innovation activities in Shanghai are further evaluated. Lessons learnt from the benchmarked science parks and policy implications for facilitating the innovation ecosystem are addressed.

科学园和创新政策的主要任务是驱动创新资源和培育新兴产业，而政府与学术界，产业界的合作以及生态系统的建立则至关重要。为了研究协作生态系统可持续发展的主要驱动力，本文基于从上海张江科学园（简称张江公园）获得的历史数据，评估了上海科学园的技术创新和生态系统。通过系统思考和因果循环分析来探索协作生态系统的结构以及对科学园的政策影响的思考。通过系统映射和实证研究确定了政府在科学园区和创新生态系统中的作用。进一步评估了张江​​公园政策的经济影响和上海创新活动的表现。讨论了从基准科学园中学到的经验教训以及促进创新生态系统的政策含义。
