本文以天津市43篇科技成果转化相关政策文本为研究对象，基于“政策工具—政策目标”二维框架剖析其结构特征与优化路径。研究发现：（1）政策工具结构失衡：供给型（49.74%）与环境型工具（46.56%）占比过高，需求型工具仅占3.70%，市场拉动作用明显不足；（2）重技术转移、轻产业化：政策聚焦技术转移与应用推广（69.31%），产业化阶段支持薄弱（4.76%）；（3）政策工具与转化阶段适配性不足：研发阶段忽视成果质量提升（“成果特性”工具仅占7.14%），产业化阶段过度依赖短期“资金支持”，缺乏长效金融税收机制；（4）缺少实施细则，削弱政策执行力。建议强化需求型工具应用，均衡三阶段政策布局，建立“阶段—工具”动态适配机制，并完善配套细则以提升效能。

This study examines 43 policy documents on science and technology achievement transformation issued by Tianjin Municipality, analyzing them through a two-dimensional framework of "policy tools - policy objectives" to dissect structural characteristics and optimization pathways. Findings show: (1) Imbalanced policy instrument structure: Supply-side (49.74%) and environmental instruments (46.56%) dominate, while demand-side instruments account for merely 3.70%, resulting in weak market pull; (2) Overemphasis on technology transfer at the expense of industrialization: Policies disproportionately focus on technology transfer and application (69.31%), with weak support for industrialization stage (4.76%); (3) Insufficient adaptability between policy tools and transformation stages: The R&D phase neglects quality enhancement (“quality characteristics of outcomes” instruments: 7.14%), while industrialization relies excessively on short-term “funding support” without long-term fiscal and taxation mechanisms; (4) Absence of implementation rules weakens policy effectiveness. Recommendations include strengthening demand-side instruments, balancing three-stage policy allocation, establishing a dynamic “stage instrument” adaptation mechanism, and refining supporting rules to improve policy effectiveness.
