Development trend of food grade metal cans

The forecast of the development trend of the food-grade metal can industry is based on past and present information, using certain scientific means and methods, to predict and estimate the future development direction of food-grade metal cans.
 

1. food grade metal can industry development trend analysis principle

1. Principle of knowability
The principle of knowability is also known as the principle of regularity. Through the investigation of the development and change of the food grade metal can industry, the future development of the food grade metal can industry is predicted. Predictive analytics is a trend judgment based on the principle of knowability.
 

2. Continuity principle
We assume that the food-grade metal can industry enterprises in the production and operation process, the past and present of a certain law of development will continue, and determine the past and present development conditions are also applicable to the future. According to the principle of continuity, the future of the food-grade metal can industry can be speculated as an extension of history.
 

3. Correlation Principle
There is an interdependent and mutually restrictive relationship between the development of the food-grade metal can industry and its related industries. Its future development trend and situation will inevitably appear under the joint action of many factors. According to the correlation between the influencing factors, the future market development regularity of the food grade metal can industry is judged.
 

4. Controllability principle
The food grade metal can industry has its own development law. Under the condition of mastering its regularity, the subjective initiative and creativity of food grade metal can enterprises can make the food grade metal can industry develop in the direction in line with people's wishes. This is the principle of controllability.
 

2. Food Grade Metal Can Industry Development Trend Analysis Method

(I) quantitative analysis
Quantitative analysis mainly applies mathematical methods and various modern calculation tools to scientifically process economic information, establish a mathematical model of prediction and analysis, reveal the regular relationship between the relevant variables, and make a prediction conclusion of the food-grade metal can industry.
 

According to the way in which the data are processed, quantitative analysis can be divided into the following two types:

1. Trend prediction analysis method
Trend prediction analysis method, also known as time series analysis method or extrapolation analysis method, arranges the historical data of the food-grade metal can industry in chronological order, and uses mathematical methods to process, calculate and predict the future development trend of the food-grade metal can industry.

Such as: arithmetic average method, moving average method, trend average method, weighted average method, exponential smoothing method, time series analysis method.

2. Causal prediction analysis.
The causal prediction analysis method is a method of establishing the corresponding causal mathematical model for prediction analysis according to the regular relationship of interdependence and mutual restriction between the food-grade metal can industry and its related industries.

Such as: the current profit analysis method, input-output analysis method, regression analysis method, econometric method.
 

(II) qualitative analysis

Qualitative analysis, also known as "non-quantitative analysis", refers to the food-grade metal can industry professionals based on personal experience and knowledge combined with the characteristics of the food-grade metal can industry for comprehensive analysis, the future status of the food-grade metal can industry And the development trend of a kind of prediction method to make speculation.
 

Qualitative analysis is also known as "judgment analysis" and "collective opinion method" in Western countries ". Commonly used methods of analysis are:
 

1. Purchaser intent investigation method
The buyer's intention survey method is a method of analysis by directly asking downstream users in the food-grade metal can industry about their needs over a period of time.
 

2. Sales staff opinion synthesis method
When it is not possible to directly investigate the buyers of food-grade metal cans or the cost is too high, the market demand and enterprise demand can be judged by asking the sales staff.
 

Because the sales staff are close to the downstream users of the food-grade metal can industry and are familiar with the situation, the estimation of a number of sales staff can often get valuable results.
 

3. Expert opinion law
The expert opinion method, also known as the Delphi (Delphi) method, was proposed by the RAND Corporation in the late 1940 s.
 

When using the expert survey method, first form a panel of experts composed of dealers, distributors, market influence consultants or other authorities, the number should not be too large, generally about 20 people.
