为什么要推进农业和农村经济结构的战略性调整?

答案

参考答案:

改革开放以来,农业和农村经济结构调整已经取得了显著成效。但是,应当承认过去农业和农村经济结构的调整仍然是初步的、低层次的和阶段性的。进入新的发展阶段之后,农业和农村经济结构性矛盾日益突显出来。突出表现在三个方面;

一是产品质量不高,大路货多,名优产品比例低。

二是一般性品种多,专用品种少;初级产品多,加工产品少。

三是虽然农业生产的区域化分工有了很大进展,但区位比较优势尚未充分发挥出来,区域性农作物不同程度地存在大而全、小而全问题。在结构调整中,地区之间重复投入,常常一哄而上,带有很大的盲目性,造成了过度的盲目竞争和资源浪费。四是乡镇企业结构不合理,与城市工业相雷同,第三产业发展不足。

发展农村经济,必须推进农业和农村产业结构的战略性调整,全面提高农业和农村经济发展的质量和效益。要按照增加农民收入,提高产品竞争力,确保粮食安全,实现可持续发展的要求把握好调整的方向。
