“多规融合”的国土空间规划兼具区域发展规划和环境规制的功能，是经济新常态下国家平衡经济增长和环境保护的有力政策工具，而各地普遍实施的国土空间规划能否促进重点开发区域的经济增长，有待实证检验。以武汉城市圈空间规划为例，本文利用2002-2012年间湖北省74个县（市、市辖区）域面板数据，采用双重差分倾向得分匹配方法研究国土空间规划对重点开发区域经济增长的影响。实证结果表明：第一，国土空间规划显著地促进了重点开发区域经济的增长，但对区域内不同行政级别的市辖区和县（市）的经济增长速度具有不同的推动作用，具体表现为分别提高市辖区和县（市）级GDP增长率2.4和1.1个百分点，这一结论在对研究方法的匹配技术进行稳健性检验后依然成立。第二，对国土空间规划推动重点开发区域经济增长实现机制的进一步分析表明，武汉城市圈空间规划实施后，由于区域经济一体化进程的加快和地区之间经济联系的加强，武汉作为区域经济增长极，对相邻市、县的经济溢出效应更加明显，从而推动相邻区域的经济增长。上述研究结论对目前广泛实施的国土空间规划具有重要的政策含义，鉴于国土空间规划推动市辖区经济增长的速度要明显快于县或县级市，今后规划政策的调整要在保持重点开发区域整体经济不断提升的同时兼顾地区间的协调发展，避免空间规划的实施导致内部区域发展差距拉大;在重点开发区域经济得到发展的同时，要逐渐形成其规模集聚效应，为农产品主产区和生态功能区的人口转移提供基础，进而带动整个国土空间的可持续发展。

英文摘要：

National Spatial Planning that integrate multiple planning has the function of regional development planning and environmental regulation. It is a powerful policy tool to balance ~：onomic growth and environmental protection in new normal economy. Can the national spatial planning around the universal implementation promote the key development areas＇ economic growth should be empirically tested. Taking the spatial planning of Wuhan urban agglomeration for an example, by using county-level panel data of 74 counties （cities, districts） in Hubei Province during 2002 -2012, this paper analyzes the effect of national spatial planning to economic growth in key development areas based on PSM-DID model. The results show that：① The national spatial planning promoted economic growth in the key development regions significantly. However, it plays a different role to promote economic growth in the municipal district and country （city） at different administrative levels. The GDP growth rates of municipal district and county（city） are 2.4 and 1.1 percentage points,respectively. And these results are robust by changing the match technology of the method. ② We do a further analysis about the implementation mechanism of the national spatial planning to promote economic growth in the key development regions. After the implementation of the planning of Wuhan urban agglomeration, the regional economic integration is accelerating and economic ties are strengthened between regions. Because Wuhan City is a regional economic growth pole,its economic spillover effect is more apparent in adjacent regions. So, it improves the economic growth of neighboring areas. The above conclusions on national spatial planning which is now widely implemented have important policy implications. Because the speed that the national spatial planning promote economic growth in the municipal district is faster than that in the county or county-level city, the adjustment about the planning should take the balanced development among regions
