沿海经济带在“1+3”功能区四位一体整体布局中至关重要。江苏省沿海地区主攻现代海洋经济，而临港产业则是核心。近年来三市临港产业取得了长足的发展，但面临发展瓶颈，动力不足，亟待从政府驱动转变为“链主”驱动，引进或培育本地特色产业中的龙头企业或“链主”企业，并通过相关政策举措鼓励其发挥专业优势或市场优势引进、投资或孵化产业内有竞争力或发展潜力的企业及项目。“链主”驱动模式的成功与否关键在于“链主”的选择是否恰当，必须符合行业有影响力、专业研究力量强大、与政府有良好沟通协作、资金实力雄厚等特征，最理想类型应是国有企业，特别是央企。促进“链主”驱动发展，一是要全力推进快速交通基础设施的建设，二是要尽快制订落实鼓励人才发展的政策支持，三是要努力营造科技创业的良好氛围，四是要加快发展沿海三市的生活性服务业。
