With the continuous improvement of living standards, the total amount of\nsocial consumer goods in Chinaâ??s economic development has occupied an\nimportant position. Its fluctuations can indirectly reflect the demand and\npurchasing power of commodities, thus affecting the stateâ??s macroeconomic\nregulation and control. This paper selects the total amount of social consumer\ngoods in China from August 2005 to February 2019. Using EViews 7.2 software,\nthis paper makes use of the correlation analysis of sequence fluctuation\nin econometrics and financial time series, and finds the best fitting EGARCH\n(1,1) model based on ARMA (1,0) to conduct an empirical analysis of the total\namount of social consumer goods in China, and concludes that the total\namount of social consumer goods in China has leverage effect.
