1、影响黑龙江省经济进展因素的经济学分析09区域经济学 许文华 2022651008摘要:作为“东北老工业基地”振兴的主力战场,黑龙江省全省的结构调整和经济进展有 了长足的进步,但是在进展中也存在一些问题和困难,需要我们仔细重视、讨论并加以改进, 本文就影响黑龙江省经济进展的因素进行了计量经济学分析,并提出了一些的建议。关键词:GDP地区生产总值;固定资产投资;社会消费品零售总额怎样才能够使黑龙江省经济又快又好进展?在经济建设过程中应留意哪些方面,下面我 选取了固定资产投资、社会消费品零售总额、进出口总额等影响经济进展的几个因素进行计 量经济学分析。表1资料来源:黑龙江省统计年鉴(2022)年份地

8、x4回归参数0.754403表示:在其他条件不变的状况下,社会消费品零售总额每增加1亿元,GDP相应增加0.754403亿元。这说明,促进黑龙江省经济进展的主要缘由是社会消费品零售, 该模型提示我们在进展经济的过程中应大力促进居民消费。一、建立模型并回归依据计算国民生产总值的支出法可知:GDP=消费支出+投资支出+政府支出+净出口。结 合本文选取的相关数据,模型的函数形式可为:Y=P()+P1 X.+P2 X2+P3 X3+p4 X4+p5 X5+p6 X6+u;运用OLS估量方法对式1中的参数进行估量,得回归分析结果(表2):Dependent Variable: YMethod: Leas
