中国马铃薯生产区域格局变化及其成因实证分析——基于1995～2010年省份面板数据

Empirical Study on Variation and Contributing Factors of Regional Potato Production Structure in China: Based on Panel Data of Provinces from 1995 to 2010

中国马铃薯生产具有稳定的区域变化特征,西部省区对全国马铃薯总产量的贡献地位在逐步巩固,中部和东部省区对全国马铃薯总产量的贡献地位在逐步下降。面板数据模型实证显示,非农产业就业机会、农村人均经营耕地面积以及当地城镇人均薯类消费支出是决定中国马铃薯生产区域特征的重要影响因素。

This paper attempts to describe the regional characteristics of China＇s potato production and to find out their main contributing factors. Based on the dynamic computation and analysis of statistics of the respective proportion of the potato production of 25 provinces in the total amount of China during 1995- 2010, significant and stable regional characteristics were revealed. The potato production in western provinc- es had a greater proportion in national total potato production and the central and eastern provinces were in the opposite. Then, with the panel data model, this paper analyzed the contributing factors of the regional characteristics. The empirical results showed that the rural people＇s non-agriculture income proportion, per capita cultivated land in rural areas and the per capita potato consumption expenditures of local urban peo- ple were the important influencing factors of regional characteristics of China^s potato production.
