海南GDP三大需求要素的贡献度和相关性研究

A Positive Analysis of the Contribution of the Three Major Demands Factors and Their Relevance to GDP of Hainan Province

采用支出法计算出的国内生产总值(GDP)由一个国家或地区所有常住单位在一定时期内的最终消费即消费需求、资本形成总额即投资需求,以及货物和服务的净出口三部分构成。三大需求各增量之和即为当年GDP总增量。三大需求的数量、结构、增长率及其相关性,决定了经济增长的数量、速度和质量。本文运用标准的宏观经济学分析框架,采用可比较的相关数据,就三大需求对海南GDP的贡献度及投资与消费的相关性作实证研究。

GDP measured by expenditure consists of final consumption （consumption demand）, total investment forming （investment demand）, net export of goods and service （abroad demand）. And the annual growth of GDP is reflected in the sum of increments of the three major demands in the same year. The quality and the quantity, as well as rate of economic growth are determined by the quantity, structure, the rate of growth, and relevance of the three key demands. In this article, the author conducts a positive analysis of the three major demands in terms of their contribution to GDP of Hainan Province, and their relevance to investment and consumption, on the strength of the standard macroeconomics analysis model and comparable relevant data.
