调整结构促进经济增长有两种基本模式：均衡发展模式和非均衡发展模式。我国现在应采取适度非均衡发展模式，国宏观调控主体权威不足和市场还没有完全发育成熟。根据以上情况湖南省应采用以机械电子和石油化工为主导行业的适度非均衡发展模式。 There are two basic modes of adjusting structure to promote economic growth: balanced development mode and unbalanced development mode. At present, China should adopt a modest and non-balanced development model, which lacks the authority of the country’s macroeconomic regulation and control and the market has not yet fully developed. According to the above situation, Hunan Province should adopt a modestly unbalanced development mode dominated by machinery, electronics and petrochemical industry.
