我国农药制造业技术效率的省区差异及影响因素分析
Provincial Difference of Technical Efficiency in Pesticide Manufacturing Industry and Its Influencing Factors in China
摘要
Abstract
The technical efficiency of pesticide manufacturing industry in various provinces was measured by data envelopment analysis (DEA). The factors influencing technical efficiency of pesticide manufacturing in various provinces during 2002-2007 were analyzed using Tobit regression model. Results showed that during the research period the average technical efficiency level of pesticide manufacturing in various provinces was over 0. 75, with rising trend in fluctuation, but not high. The relative technical efficiency was various among provinces, with the highest of 1. 870 6 in Inner Mongolia and the lowest of 0. 519 3 in Heilongjiang. The difference of technical efficiency level displayed obvious divergent trend during 2002- 2004, but from 2004 to 2007 it presented significant convergence in whole. Industry cluster and capital-labor ratio had significant positive correlation effects on the efficiency of pesticide manufacturing in various provinces, with separate coefficients of 3. 050 994 and 0. 193 721. Technical equipment and industrial scale showed significant negative correlation effects,with coefficients of -1. 344 819 and -0. 123 258.关键词
