采用1990-2009年黔川桂三省各自三大需求与地区生产总值的时间序列数据,运用定性与定量相结合的研究方法,对三省三大需求与经济增长的关系.进行了比较研究.研究结果显示:消费对三省经济增长的推动作用不断降低,但对贵州省经济增长的影响仍十分显著;投资对三省经济增长的推动作用不断提高,并已成为三省经济增长的最主要动力.从经济增长方式上看,贵州已由消费主导型变为消费、投资并重的方式;四川由消费驱动为主、投资驱动为辅变为投资驱动为主、消费驱动为辅的方式;广西也由消费主导型变为投资驱动为主、消费驱动为辅的方式.另外,出口对三省经济增长的推动作用不明显.
The paper makes a comparative study of the relationship between the three demands and economic growth in Guizhou, Sichuan and Guangxi by using their respective time series data from 1990 to 2009 and the combination of qualitative and quantitative methods. The results showed that the promoting effect of consumption towards the economic growth in three provinces was on the decline, but still played a vital role in the economic growth in Guizhou; the promoting effect of investment towards the economic growth in three provinces is on the rise, and has become the main power of the economic growth in three provinces. The economic growth pattern showed that Guizhou had already changed from consumption to both consumption and investment; Sichuan had already changed from consumption promotion, investment complement to its opposite; Guangxi had already changed from consumption to investment promotion and consumption complement. In addition, export plays a tiny role in the economic growth in three provinces.
