晋陕甘宁地区农业可持续发展能力的比较研究

晋陕甘宁地区处在我国的干旱半干旱地带，又同为我国水土流失严重和生态环境脆弱的省区，分析研究和掌握该地区农业发展的现状及其可持续发展的能力，具有很重要的意义。利用比较优势理论，通过比较所选择的各项指标在全国的相对排序，并计算各“相对资产与负债”值；然后分析该地区的农业发展现状及其可持续发展能力。研究认为，晋陕甘宁地区为农业发展的较强不可持续发展地区；其中，山西和陕西省为不可持续发展省，甘肃省和宁夏自治区则为农业发展的强不可持续地区。在此基础上，提出了本区农业发展的基本对策。

Study on the Comparative Ability of Agricultural Sustainable Development of the Provincial Regions of Shanxi,Shaanxi,Gansu and Ningxia

The study region is composed of Shanxi, Shaanxi, Gansu Provinces and Ningxia Hui Autonmous Region (SSGN Region), which is a zone of aridity and semi aridity of China with serious soil erosion and frail ecological environment.It is very important both to study its situation of agricultural development and to realize its ability of sustainable development.On the basis of comparative superiority theory, a relative assets/debt assessing method is used to gain relative net assets values (comparative superiority) of the four provincial units.The calculated result shows that the SSGN Region is unsustainable in agricultural development.Both Shanxi and Shaanxi are at unsustainable level, Gansu and Ningxia are at strong unsustainable level.Moreover, some primary measures of agricultural development in SSGN Region are put forward.
