Research on Regional Comprehensive Production Capacity of Hog Industry in China with the Constraints of Resources and Environment

Abstract:

This paper designed a systematic evaluation methodology to study the regional comprehensive production capacity of hog industry in China. A three-layer evaluation index system of comprehensive production capacity of hog industry was established. The index system included 26 indicators and mainly covered seven respects, namely natural resource condition, feed supply capacity, current status of hog production, costs and returns of hog production, agricultural foundation, support capability of animal science and technology, and ecological environment condition. Then based on the index system, applied entropy weight method, grey relational analysis and principal component analysis, the comprehensive production capacity of hog industry of 31 provinces and municipalities in China in 2000, 2005 and 2010 was evaluated respectively. The consistency of these three methods was examined by Mann-Kendall test. A combined evaluation was conducted and reasons led to the great variation in ranking for some provinces and municipalities during the period of 2000-2010 were analyzed. Applied hierarchical clustering method, 31 provinces and municipalities were divided into four groups and the regions which were appropriate for hog farming and which were not were figured out.
