摘　　要：运用AD-AS模型对中国经济增长的动因进行详细分析,发现中国经济长期保持快速增长有来自总需求和总供给两方面的动因。在需求方面,投资增长、政府购买支出增长、净出口增长和货币供应量的不断增加提高了总需求水平,从而拉动了经济增长。在供给方面,人口数量的增加和人口质量的提高是增加总供给的必要基础条件;劳动力从一次产业向二次、三次产业的转移没有降低一次产业的产量,反而极大地提高了二次、三次产业的生产能力;技术水平的提升提高了要素的边际产出能力,改善了生产函数;经济改革不断深入,释放了巨大的经济活力,调动了无穷的生产潜力。这些因素共同形成了增加有效供给的合力,进而推动了经济增长。供给方面的因素是中国经济长期保持快速增长的特色因素,也是区别于很多发达国家的特殊因素。研究最后得出中国完全有可能在今后相当长的一段时期内继续保持经济快速增长的结论。The motivation and causes of economic growth in China are analyzed in detail by applying AD-AS model, which finds that there are two kinds of motivations and causes of aggregate demand and aggregate supply that maintain long-term rapid economic growth in China. From aspect of demand, the growth of investment, government procurement expenditure, net export and money supply improve the level of aggregate demand, which pulls economic growth. From aspect of supply, the increase of population and the improvement of population quality are necessary basic conditions of increasing aggregate supply; the transfer of labour force from the primary industry to the secondary and the tertiary industries does not reduce the output of the primary industry, however, it improves the production capacity of the secondary and the tertiary industries greatly; the development of technological level improves the marginal output capacity of factors and perfects the production function; and the continuous deepening economic reform releases huge economic vitality and arouses infinite potential of production. These factors compose the resultant force of increasing effective supply together, which promotes economic growth. Supply factor is the characteristic factor of maintaining long-term rapid economic growth in China, and it is the special factor distinguished from many developed countries. Conclusion is drawn at last that it is completely possible for China to maintain rapid economic growth for a longer period of time in the future.
