蚕茧价格对蚕业生产的作用分析

Analyses on Effects of Cocoon Price on Sericulture Production

根据 1 979～ 1 996年的全国蚕茧产量和平均收购价格的变化 ,分别计算价格弹性系数 ,以及价格和产量对产值的贡献度 ,依此判明价格对蚕业发展的影响。研究表明 :蚕茧价格对蚕业发展呈弱波趋势。造成这一趋势的原因是 :( 1 )农家养蚕经营规模小 ;( 2 )农村劳动力分流 ;( 3 )养蚕经营比较效益下降 ;( 4)

Based on the variations of national cocoon outputs and average purchasing prices from 1979 to 1996,the coefficient of price elasticity and the contribution ratio of price and production to output value were calculated respectively,and then the effect of cocoon price on sericultural development was evaluated.Analyses of practical cases indiceted that the relationship between cocoon price and serieultural development could be described as weak wave pattern,the reasons of which were summarized as follows:(1)Silkworm rasing was operated individually by families in small scale.(2)Rural labour power was transferred to other industries.(3)Specific profits from silkworm raising reduced.(4)Bubbling output value formed due to cocoon purchasing battle.
