With the development of fishery production in China,the demand for ice in fishery is gradually increasing,and there is no official statistics for ice demand in fishery at present.So that ice-making enterprises cannot adjust production scale according to market demand.Ice-making enterprises have no control over the structure and development trend of ice consumption market,which directly causes the blindness of the production.In this article,through the establishment of the classical linear regression model,the ice volume curve of fishery in 1995—2016 is estimated and fitted with the national trend of ice production,indicating that the estimated results are relatively objective and accurate,in line with the actual situation of China's fishery ice.Through the heteroscedasticity testing,stationarity test,cointegration test and a series of metrology inspection,we find that there is no heteroscedasticity in the regression model,and there is a stable and long-term equilibrium relationship between the variables.Therefore,the estimation results are statistically significant.From the overall trend point of view,China's fishery ice consumption is growing,indicating that China's fishery production scale is showing a growing trend.Further research shows that the estimated amount of ice in the first fishery industry in China is relatively large,which is 40.74%,but the average annual growth rate is 3.04%.The estimated consumption of ice in the fishery secondary industry is the smallest of the three industries,about 12.17%,but the annual increase is the highest,reaching 7.99%.The estimated amount of ice in the third fishery industry is 47.09%,and the annual growth rate was 4.73%.By 2030,the total amount of ice in fisheries is expected to reach 1927 million tons.
