[Abstract]:Since the reform and opening up, Chinese tobacco has experienced from small to large, from weak to strong, from scattered to centralized, from miscellaneous to big brand. At present, affected by the changes in the domestic and foreign environment and the downward pressure on the economy, Chinese tobacco is in a situation where the growth of sales volume is becoming more difficult, the structural upgrading is facing bottlenecks, the supply and demand are not balanced, and the overall development rate of the industry is slowing down. For this reason, According to the development trend of the industry, according to the measures of "cigarette market-oriented reform", taking "demand forecasting" as the foothold, combining with the characteristics of cigarette marketing, this paper forecasts the demand of cloud cigarettes in the next few years. It provides useful information and reference for the development of Yunnan Zhongyan Company in terms of development strategy planning, target decision making and cigarette task allocation. First of all, this paper describes the concepts, categories and functions of prediction theory, describes the development and use of prediction methods at home and abroad, and further compares the advantages and disadvantages of different prediction methods. The combined prediction model used in this paper is analyzed emphatically. Secondly, it analyzes the performance, competition degree, brand status, sales situation of one or two types of cigarettes in the domestic cigarette market, and analyzes the development situation of the industry and the promotion of market-oriented reform. It is concluded that the implementation of cigarette demand prediction is imperative and will become the core and focus of cigarette marketing in the future. Then, through the analysis of importance, economy and other multi-dimensional analysis, we find out the eight factors that affect cloud cigarette prediction. In combination with objective conditions, the data collected from the Yunnan Branch of Xinhua News Agency, the No.1 Project system of the State Tobacco Monopoly Administration, the National Bureau of Statistics of the people's Republic of China and other reference materials were collected, and the stepwise regression analysis was carried out using SPSS software. The variables of nonconformity test were eliminated one by one, and the three most closely related factors with cigarette sales were obtained, and the multiple regression model was used to predict cigarette sales. Because the model is not sensitive to the objective effects such as cigarette policy factors, major technical changes and so on, and these factors are extremely important to cigarette sales, the predicted results are limited to a certain extent. For this reason, this paper adopts "quadratic exponential smoothing" to increase the objective situation such as periodic fluctuation and environmental change, and forecasts the cigarette sales again, and compares the results of two different forecasting methods. It is found that "multivariate regression model" fully applies historical data information, but lacks consideration of objective factors such as environment and policy, while "quadratic exponential smoothing" can fully consider the objective influence. However, the use of data information is not as good as "multiple regression model", and the application of the two methods can make up for each other and avoid the defects, so this paper finally chooses "combination forecasting model" to forecast cigarette sales. It is found that the prediction results of this method are indeed the closest to the future sales trend and the prediction accuracy is also relatively high. It has important reference value for cigarette sales and product planning in the future. Finally, by analyzing the future national policy direction, the industry development environment, the development prospect of Yunnan cigarette, the opportunities and challenges that may be faced, and referring to the forecast result data, this paper makes a pre-judgment on the cigarette marketing situation and operates in the market. Four aspects of cigarette value promotion, resource optimization and scientific and technological innovation are put forward for the development of cloud cigarettes.
