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。
Using the time series data of the three major demands of each of the three provinces in Guangxi Zhuang Autonomous Region from 1990 to 2009 and the GDP of the three provinces, a qualitative and quantitative study of the relationship between the three major demands and economic growth in the three provinces was carried out. The results show that consumption has a decisive influence on the economic growth in the three provinces but still has a significant impact on the economic growth in Guizhou Province. The promotion of economic growth by the three provinces has been continuously boosted by investment and has become the most important driving force for economic growth in the three provinces. From the perspective of economic growth, Guizhou has changed from a consumer-oriented model to an equal mode of consumption and investment. Sichuan is dominated by consumption and investment-driven into a predominantly investment-driven mode of consumption-driven supplementation. Guangxi also consists of Consumer-led into investment-driven, consumer-driven approach. In addition, the export promotion of the economic growth of the three provinces is not obvious.
