关于加快我国奶产业发展的思考

奶产业是事关经济发展和社会进步的重要产业。加快奶产业发展，是我国新阶段农业和农村经济发展的一项重要任务，对于带动农业和农村经济结构战略性调整，发展二、三产业，增加农民收入，促进经济发展，提高人民的健康水平，具有重要意义。１ 我国奶产业发展相对滞后改革开放以来，我国奶产业生产发展很快。１９９８年全国奶类产量由１９８０年的１３７万吨增加到７４４．５万吨，年均递增率达到９．８％，奶制品年人均占有量达到６．１千克。１９９９年奶类产量达到８０７万吨，比上年增长８．４％，奶类人均占有量达到６．５千克ｃ２００…     

2002年玉米市场展望

１玉米生产单从产量上看，国内玉米产量已经连续２年维持较低水平，但是２００１年与上年相比是增产趋势。据农业部统计数据，２００１年我国玉米产量达１．１５亿吨，比上年的１．０６亿吨增产９００万吨，增幅可观，玉米供给情况好于上年，对价格上涨的压力较大。对于２００２年玉米生产现在预测显得为时过早，但是从目前的玉米市场价格看，持续低迷的玉米价格可能影响到今年玉米播种面积，进而对今年的玉米生产产生影响。２玉米消费我国目前玉米消费主要包括饲料消费、工业消费和口粮消费，有关方面数据显示，２００２年国内玉米消费总量…
