GNP是国民生产总值（Gross National Product）的缩写，它是指一个国家或地区所有常住单位在一定时期内生产活动的最终成果。GNP是国民经济核算的核心指标，也是衡量一个国家或地区经济状况和发展水平的重要指标。

GNP的计算方法有三种：生产法、收入法和支出法。生产法是从生产过程中生产的货物和服务总产品价值入手，剔除生产过程中投入的中间产品的价值，得到增加值的方法。收入法也称分配法，是从生产过程创造收入的角度，对常驻单位的生产活动成果进行核算的方法。支出法也称最终消费法，是从最终使用的角度反映国内生产总值最终使用去向的一种方法。

GNP的意义在于，它能够反映一个国家或地区的经济总体规模和水平，也可以反映一个国家或地区的综合国力。同时，GNP的增长也代表着一个国家或地区经济发展水平和人民生活水平的提高。

GNP is the abbreviation of Gross National Product, which refers to the final output of production activities of all resident units within a country or region during a certain period of time. GNP is the core indicator of national economic accounting and an important indicator to measure the economic status and development level of a country or region.

There are three methods of calculating GNP: production method, income method and expenditure method. The production method starts from the total product value of goods and services produced in the production process, deducts the value of intermediate products inputs in the production process, and obtains the value-added method. The income method, also known as the distribution method, is a method to calculate the results of production activities of resident units from the perspective of income created in the production process. The expenditure method, also known as the final consumption method, reflects the final use of domestic production in one country or region from the perspective of final use.

The significance of GNP lies in that it can reflect the overall size and level of a country or region's economy and also reflect the comprehensive national strength of a country or region. At the same time, the growth of GNP also represents the improvement of a country or region's economic development level and people's living standards.
