中文摘要：

山东沿海城市带主要涉及青岛、烟台、威海、潍坊、日照、滨州、东营、济南、淄博九个城市，实现九市地方政府的跨政区合作、优势互补、共同发展是促进山东沿海城市带以及整个山东省经济、社会高效发展的有效手段。山东沿海城市带城市主要通过“核心一外围”式和平级城市间合作两种模式在产业、交通、旅游、生态环境以及科技人才方面：开展合作，其主要合作机制分为制度化合作机制、区域性发展规划以及行政协议三种类型。各城市的合作取得了一定的成效，但仍然存在跨政区合作的组织机构缺位、跨政区合作的政策工具残缺、跨政区合作参与主体单一、跨政区合作常态化程度低等问题。今后应该从健全合作的组织机构、完善跨政区合作治理工具、扩大跨政区合作的参与主体、保证跨政区合作的常态化等方面着手以促进山东沿海城市带的区域协调化与经济一体化发展。
