Market analysis editor
The national population is 654.38+0.3 billion. Take a province with a middle population as an example. If the population of 40 million is calculated as 20% of primary and secondary school students, there are at least 8 million students, and then calculated as 5% of the purchase volume (multifunctional protractor for Class A stationery), that is, 400,000 pieces, and calculated at the reference unit price of 50- 10 yuan, the output value is 200-. The sales forecast of type B teaching assistants is 20,000 pieces, and the output value is between 600- 1 10,000 yuan at the unit price of 30-50 yuan. The sales volume of Class C tools is estimated to be 20,000 pieces, and the unit price is 60- 100 yuan, so the output value is120-200 million yuan.
In particular, type A and type B products are mainly made of plastic materials, which have wide sources of materials, low cost, simple structure, convenient manufacture, strong practicability and large application market.
If you invest more than 30% of the cost, you can get more than 60% of the profit.
The above is the estimated sales volume of a province. If this product is officially put into production, the sales volume in the national stationery, teaching AIDS and tools market should be more than several times that of the above evaluation, and the demand exceeds the supply, and the output value should exceed10 million yuan.
