湖南产业结构变动对经济增长贡献的空间分析

产业结构是经济增长的重要影响因素，合理的产业结构有助于经济的稳定增长，反之，影响经济的持续健康发展。利用（（湖南统计年鉴（2001-2011）》的相关数据，运用多部门经济模型，分析了湖南2000年来产业结构变动与经济增长的关系，发现具有明显的地域差异：从三大地区来看，Z值由大到小的空间演变基本是湘南一湘西一城市群的由南向北、由西向东梯度推进，表明湖南三大地带的经济发展水平和产业结构变动的时间基本相悖；从地级行政区来看，14个市州的Z值以娄底、邵阳、衡阳为中心向四周渐大；P值的空间分布呈现出与经济发展梯度推进相向的特点，产业结构调整在经济发展水平较低的湘西地区具有重要贡献。

Spatial research on the Contribution of Industrial Structure Change to Regional Economical Growth in Hunan Province

The industrial structure is a very important factor affecting economic growth. Whether regional industrial structure is reasonable or not, strongly affects the speed of the economic growth. With the method of multi-sector economic model, the paper analyzed the relationship between the industrial structure changes and economic growth of Hunan Province from2000 to 2011, then found： （1） Z value was descending space evolution from South to west ,then Changsha-zhuzhou-xiangtan urban agglomerations, which indicated the level of economic development was basically contrary to the changes of the industrial structure in Hunan three zones. （2） Z values of 14 cities were getting big from Loudi, Shaoyang, Hengyang to other areas. P values showed a gradient promote the opposite characteristics with economic development. So industrial structure ：adjustment has an important contribution in the area of the lower level of economic development, such as west of Hunan Province.
