中文摘要：

本文着重从地区差异、演变特征、战略层面和产业侧重四个方面回顾梳理长江经济带沿线省市出台的战略性新兴产业规划文本，揭示区域战略性新兴产业的政策导向，并利用统计数据对政策出台前后战略性新兴产业发展情况进行比较分析。研究结果显示：长江经济带沿线省市战略性新兴产业发展政策存在地区规模差异、政策跟进和与时俱进的显著特点；政策规划文本表现为总体规划与专项规划协同推进，且后者是直接推动力；各省市均针对特定产业采取优先发展政策，制定针对性的区域发展规划，且上海处于政策的领先地位。总体来看，长江经济带沿线省市战略性新兴产业发展政策取得了不小成效，但存在产业结构不协调问题。长江经济带沿线省市应进一步优化完善相关规划政策，以推动战略性新兴产业快速协调可持续发展。

英文摘要：

This article reviewed and combed development policies of strategic emerging industries among provinces along the Yangtze River Economic Belt focused on four aspects as follows： spatial scale capacity, time evaluation trend, strategic distribution level and industry features. The results showed that： Development policy of strategic emerging industries differs a-mong provinces in the spatial scale capacity, having the feature of policy to follow up and keep pace with times. The overall policy and specific policies to promote synergistically and the latter are the direct driving force. All of the provinces take pri-ority development policies for specific industries and Shanghai leads the policy. Overall, the policies of strategic emerging in-dustries among provinces along the Yangtze River Economic Belt have achieved a big success, but there is lack of coordina-tion in industrial structure. Provinces along the Yangtze River Economic Belt should optimize and improve relevant policies to promote rapid, coordinated and sustainable development for strategic emerging industries.
