Infrastructure Economic Accounts, economic impact by asset, industry, and asset function (x 1,000,000)

The economic contribution as a result of the production of infrastructure assets due to investment is presented for valued added (GDP), compensation of employees and number of jobs. Value-added is a key measure of economic performance. It represents the output of an industry minus the value of intermediate inputs that were used up in the production of the goods and services. Within the Infrastructure Economic Accounts, this is the value added due to an industry's production of infrastructure assets. The number of jobs represents the number of jobs held by the self-employed, employees and unpaid family workers. The compensation of employees represents the wages and salaries, and supplementary labour income due to labour inputs for the production of infrastructure assets.

基础设施资产投资所产生之经济贡献，以增值（GDP）、雇员薪酬及就业岗位数呈现。增值是衡量经济绩效的关键指标，它反映了某一产业产出减去生产商品与服务过程中消耗的中间投入价值。在基础设施经济账户中，此增值源于产业对基础设施资产的生产。就业岗位数代表了自雇人士、雇员及无偿家庭工人所持有的岗位数量。雇员薪酬包括工资、薪金及因劳动投入而导致的劳动收入，这些均与基础设施资产的生产相关。
