Abstract：Based on questionnaire survey data from five categories of marine一related employees and the general public in Qinhuangdao，Tangshan and Cangzhou cities （Hebei Province），establishes an evaluation framework encompassing seven dimensions，including input一output efficiency and marine environmental awareness，to conduct a dynamic analysis of marine ecological efficiency from 2O2O to 2024 and explore its spatiotemporal evolution patterns. Key findings reveal：significant differences in inputoutput indicators among the three cities;marine environmental protection efforts remain overly reliant on awareness campaigns，with underdeveloped public participation mechanisms;while ecological efficiency demonstrates overall improvement， regional disparities initially narrowed but later expanded， trending towards high-eficiency balanced development; higher-efficiency zones clustered northward without formed a collaborative network，exhibiting macro-level multidimensional mechanisms for marine ecological monitoring，assessment，early warning，and governance，alongside micro-level targeted measures to address identified inefficiencies.

Key words：marine ecological eficiency;expected output; Hebei Province;spatial-temporal differentiation.

在全球气候变化和海洋资源开发的形势下，海洋生态效率成为关键研究领域，主要围绕渔业经济效率评估，狄乾斌等[1评测中国海洋效率时空差异及与产业结构的响应关系，探究产业结构与生态效率的空间关联；孙康等[2研究沿海11省市渔业经济效率并分析影响因素；梁盼盼等3对经济效率进行测算评价。在研究方法上常运用数据包络分析[4]及其拓展模型[5-6]，借DEA模型[7-8]衡量海洋生态系统效率；邵春雪等[9揭示环渤海地级市效率空间演变规律；徐胜等[10]基于非期望产出SBM模型测度2011—2021年效率时空演变特征。本文以河北省沿海地级市为研究对象，理论层面构建动态评价体系，实践层面考察效率时空分异制定差异化政策，推进海洋可持续发展。

1调查实施及效率评价

1.1 问卷设计

本研究采用问卷评估体系，从资源消耗、非期望产出碳排放、期望产出、海洋感知4个维度考察河北省沿海城市的时空差异。调查覆盖3市35个县级行政区的五类涉海行业人员及公众。通过预调查验证抽样方案与问卷可行性，经信效度分析优化问卷。

1.2 问卷收发与数据处理

采用分层和多阶段抽样结合的抽样方法。调查遵循自愿原则，筛除无效问卷、标注异常答卷并提醒补填。网调严格保密信息，事前告知用途，设专用邮箱处理反馈。经严密质控，有效回收率 93.9% （涉海314份，涉海率 1.78% ）。样本数据经游程检验（ Z=0，201 P=0.741） ，观测值序列随机性未被证伪（ a=0.05 ，符合调研要求，结论具有较强说服力与推广价值。……
