【摘要】 分析了 1979～ 1995年蚕茧可比价格环比指数和蚕茧产量环比指数的变化趋势、蚕茧可比价格和蚕茧产量对蚕茧可比产值增加的贡献度以及蚕茧产量的价格弹性值的变化。结果表明 ,蚕茧产量对茧价反应的理论滞后期为 4年 ,茧价仍是制约蚕业生产发展的主要因素 ,它对蚕业生产的刺激作用并未弱化 ,蚕茧价格对蚕业生产的弱波趋势尚未表现。更多还原

【Abstract】 We calculated the comparative price,the correlative coefficient of comparative price and cocoon output by getting rid of the changes of production cost and inflation.Then we analyzed the variations of the chain indexes of comparative price and cocoon output,the contribution ratio of comparative price and production to output value,the elasticity of comparative price and cocoon output.The results stated that the relationship between cocoon price and development of sericulture has not indicated the weak wave pattern and the lagging time which cocoon output response to comparative price is about four years.更多还原
