【固定资产投资】固定资产投资是社会固定资产再生产的主要手段。通过建造和购置固定资产的活动，国民经济不断采用先进技术装备，建立新兴部门，进一步调整经济结构和生产力的地区分布，增强经济实力，为改善人民物质文化生活创造物质条件。这对我国的社会主义现代化建设具有重要意义。

固定资产投资额是以货币表现的建造和购置固定资产活动的工作量，它是反映固定资产投资规模、速度、比例关系和使用方向的综合性指标。固定资产投资按经济类型可分为国有、集体、个体、联营、股份制、外商、港澳台商、其他等。按照管理渠道，固定资产投资总额分为基本建设、更新改造、房地产开发投资和其他固定资产投资四个部分。

联营和合资企业按其是否由农村集体与个人相对控股或绝对控股，或由农村集体、个人实际管理来确定是否纳入农村固定资产投资统计范围，其投资额按实际发生额全额统计；个体工商户外雇从业人员８人以上（含８人）的按企业统计。

第二类为乡镇行政事业单位及社会群众团体。

【新增固定资产】指通过投资活动所形成的新的固定资产价值。包括已经建成投入生产或交付使用的工程价值和达到固定资产标准的设备、工具、器具的价值及有关应摊入的费用。它是以价值形式表示的固定资产投资成果的综合性指标，可以综合反映不同时期、不同部门、不同地区的固定资产投资成果。

【新增生产能力（或工程效益）】指通过固定资产投资活动而增加的设计能力或工程效益，它是用实物形态表示的固定资产投资的成果。新增生产能力的计算，是以能独立发挥生产能力或工程效益的单项工程(或项目)为对象。当单项工程(或项目)建成，经有关部门鉴定合格，正式移交投入生产，即可计算新增生产能力。

新增生产能力或工程效益有以下几种表现形式：

【Investment in Fixed Assets】 Investment in fixed assets is the essential means for social reproduction of fixed assets. By means of construction and purchase of fixed assets, more advanced technologies and equipment are adopted in the national economy, and new sectors are established, which promote the adjustment of economic structure and the regional distribution of productive forces and enhance the economic strengths so as to provide the material conditions for improving people’s livelihood.
