Spatially Aggregated Pattern Evolution of Grain Production Efficiency on County-Level——A Case Study of Hebei Province
摘要
Abstract
Food security is a strategic concern of long-term regional development.Given the rapid population growth and continuing reduction in arable lands,increasing food production efficiency becomes the key to increase food production.Using the ESDA techniques and DEA Malmquist model,in conjunction with the spatial pattern of geographical research methods,we estimated grain production efficiency of 138 counties in Hebei Province from 1990 to 2005,and discussed the evolution characteristics and patterns of spatial clustering of the grain production efficiency on the county-level in Hebei Province.Results showed that grain production efficiency of 138 counties were aggregated spatially in the provincial region;however,the inter-regional differences were reduced.The local spatial aggregation pattern of grain production efficiency indices were significant,and the evolution of spatial aggregation pattern were evident on county-level in Hebei Province from 1990—2005.This study provides methodology for estimating spatial patterns of production efficiency,scientific basis for properly regionalizing production,and regional strategy for food security.关键词
