统计指标和统计指标体系统计指标和统计指标体系统计指标和统计指标体系统计指标是说明谷体现象数量表现阴科学概念和具体数值它包括3个构成要素:指标名称、汁量单位、计算方法、时间限制、空间限制和指标数值在实际工作中.根据需要.统计指标可以专指总体现象数量表现的概念，如工业总产值、国民收入、劳动生产率等等但是只有具体数值而缺乏这个数值的科学概念，则不是统计指标统计指标主要特点是:①数量性。它反映客观事物的数量特征。雪综合性它说明的对象是总体而不是个体.它是许多个体现象的数量综合的结果。③具体性。它不是抽象的概念和数字，而是一定的具体现象的量的反映。每一个具体的统计指标都有它不同的作用，总起来说，统计指标的作用是:①它起指示器和反映一般数量关系的作用。②提供数字表明的事实，是管理和科学研究的基本根据之一。统计指标按其反映的总体内容不同，可以分为数量指标和质量指标。数量指标是说明总体外延规模的指标，亦称总量指标，例如人日数、工业总产值、商品销售额、货物运输量等等。质量指标是说明总体内部或总体之间数量关系和总体单位水平的指标，例如平均工资、劳动生产率、平均亩产量等等。由反映客观现象数量关系的若干个相互联系、相互制约的统计指标组成的整体称为统计指标体系。单个统计指标只能说明某一现象的个别侧面，统计指标体系可以从各个方面相互有联系地反映整个总体的状况。社会经济统计指标体系分为两类:第一类是基本统计指标体系;第二类是专题统计指标体系基本统计指标体系一般分为三个层次:最高层是反映整个国民经济和社会发展的统计指标体系:中间层是反映各个地区和各个部门发展变化的统计指标体系:基层是反映各企业和事业单位基本状况的统计指标体系。专题统计指标体系是为反映或揭示某一社会经济间题而专门制定的统计指际体系.如经济效益统计指标体系.少、民生活水平统计指标体系.科技进步统计指标体系等国民经济和社会发展统汁指标体系是社会经济统计指标体系的主体.以它作为中心，可以形成一个纵横交错，既有分工又有联系的统计指标体系的巨大系统在一定时期内.统计指标和统计指标体系具有相对的稳定性但是‘统计指标和统计指标体系要与社会经济发展的进程相适应不断改进、充实和完善
