中文摘要：

引入索罗斯旺模型对宏观经济增长因素进行分析。假设经济中微观个体厂商的生产函数是哈罗德中性技术进步的，每个生产者都是以利润最大化为导向安排生产计划，每个消费者在每一期的消费支出占其当期可支配收入的比例是固定不变的。在这些假设的基础上得到了人均资本存量动态变化方程，由此得到索罗关键方程，并且发现索罗关键方程的根具有稳定性。在对经济增长因素分析中发现，技术进步对经济增长的作用较资本，劳动更为显著。

英文摘要：

In this paper, we introduce Solow-swan model to analyze macroeconomic growth factors. We assume that the micro individual manufacturer＇s production function in the economy is Harold neutral technical progress, each producer＇s aim is the profit maximization ,which is the guidance to arrange production plan, each consumer＇s spend- ing accounts for the proportion of disposable income of the current period is fixed. On the basis of these assump- tions, we get the per capita capital stock dynamics equation. Then we got solo key equation. And we found root of solo key equation is stable. In the analysis of economic growth factor, we found the effect of technical progress on economic growth is much more important than capital and labor.
