甘肃省区域农业竞争力评价与时空演变分析

区域农业竞争力的提升是解决"三农"问题的关键。运用因子分析方法,对甘肃省14个地级市(州)1997、2002、2007和2012年的农业竞争力进行综合评价与实证分析,并结合不同时间断面上农业竞争力等级分布图和插值效果图,归纳总结了甘肃省农业竞争力的时空演变规律特征。结果表明:甘肃省各地市(州)农业竞争力水平差异显著,地域分布呈现出由分散向集聚发展的态势,可以划分为河西走廊超强型、陇中陇东一般型和陇南临夏甘南偏弱型3种基本类型;农业空间扩展能力与其竞争力水平高度正相关,并呈现出由极点式到点轴式再到网络化的迹象;农业政策导向驱动、资源禀赋及经济驱动、产业结构及成长驱动共同驱使农业竞争力在空间范畴上格局置换。

The evolution of spatial-temporal pattern of the regional agriculture competitiveness in Gansu Province

The promotion of regional agriculture competitiveness is the key to solve the Three Rural Issues. This paper used factor analysis to evaluate the agriculture competitiveness of 14 prefecture-level cities in Gansu Province for the years of 1997, 2002, 2007 and 2012. At the same time, we have summarized the spatial-temporal regular pattern of the agriculture competitiveness in Gansu Province by combining the level distribution and the spatial interpolation regular pattern of the agriculture competitiveness in different sections. The research indicates that there are significant imbalance of the agriculture development in Gansu Province, and the geographical distribution shows an apparent trend from dispersion to centralization, it could be classified into three basic types: strong type, moderate type and weak type, while strong type regions were Gansu Corridor, moderate type regions were East and Central Gansu, weak type regions were Longnan, Linxia and Gannan; the agriculture space expansion capability is highly positive correlated with the level of its competitiveness, and shows the indication of the extreme point to point from the point-axes to planar network; The three driving aspects of agriculture policy orientation, resources endowment and economic orientation, industrial structure growth orientation are the main driving factors which lead to the spatial pattern replacement of agriculture competitiveness.
