中国山区经济发展差异与非农产业的贡献

以地区 (市) 作为基本研究单元，选取大小兴安岭、燕山、太行山区、沂蒙山区、武陵山区、东南丘陵、喀斯特山区、横断山区、祁连山区等具有典型性的中国山区，定量分析2000年中国山区经济发展态势以及影响和制约山区经济发展的深层次因素，并与平原地区和经济发达地区进行宏观、中观层面上的多方位对比分析。结果显示: 中国山区人均GDP的区域变化特征与山区非农产业人均增加值发展态势呈正相关；各类山区农业产业人均增加值表现为一条无差异曲线，即山区居民家庭收入的差距，主要来自非农产业，农业产业收入退于次要地位，非农产业人均增加值决定中国山区的经济发展的空间分异。

Economic Development Differences Related to Off-farm Industries' Contribution in Mountainous Areas of China

Based on the units of 26 prefectures and 66 counties, 9 typical mountainous areas, including Da-Xiao Hinggan Mountains, Yanshan Mountains, Taihang Mountains, Yimeng Mountains, Qilian Mountains, Hengduan Mountains, Karst Mountains, Wuling Mountains and Dongnan Mountains, were selected to analyze the state of off-farm income. After comparison with plains as well as developed regions, the results show that the average agricultural output per capita in plain and mountainous areas is both lower than 2000 yuan RMB without much difference, but the difference is much bigger in output value of off-farm industries between plain and mountainous areas. The output value of off-farm industries accounts for about 90% of GDP in plain areas, but in mountainous areas it is 70% of GDP. The authors therefore conclude that the "poverty" in mountainous areas or the gap between mountainous areas and plain areas lies in the underdevelopment of off-farm industries in mountainous areas.Also, this study indicates that agricultural growth trend in China is strongly correlated with growth of off-farm industries--the curve of net income from off-farm industries reflects the general characteristics of net income of households. That is to say that increase of net income of farm households is chiefly from off-farm industries, more than from agriculture.
