摘要: 从总额和结构角度分析了农垦系统固定资产投资与经济增长现状,发现固定资产投资与生产总值之间存在较高的同步性和一致性。根据2004—2017年中国农垦统计年鉴14年的时间序列数据,以简单线性模型和只包含资本的柯布-道格拉斯生产函数模型,实证检验固定资产投资和经济增长之间的相关关系。结果表明,两者存在显著相关关系,每增加1个单位固定资产投资,其生产总值将增加1.292个单位;推动农垦系统经济增长的主要因素是固定资产投资所代表的资本要素,其资本对经济增长的贡献率为67.9%。Abstract: Current situation of fixed asset investment and economic growth in agricultural reclamation system was analyzed from perspective of total amount and structure,and it was found that there was a high synchronization and consistency between fixed assets investment and GDP.Based on the time series data of the Statistical Yearbook of Agricultural Reclamation of China from 2004 to 2017,a simple linear model and a Cobb-Douglas production function model containing only capital were used to empirically test correlation between fixed asset investment and economic growth.Results showed that there was a significant correlation between fixed assets investment and economic growth.For every unit of fixed asset investment increased,the GDP would increase by 1.292 units.Main factor promoting economic growth of agricultural reclamation system was capital factor represented by fixed asset investment,whose capital contribution rate to economic growth was 67.9%.
