Why are there state subsidies for buying Lenovo laptops now? Thank you

One is trade-in, which is to exchange old household appliances for new laptops, and you can get a subsidy of 10% of the new laptop price. If you buy a new laptop, you can trade it with any old household appliances, but there is an upper limit for the subsidy. I remember The maximum subsidy for buying a TV is 400, and the same seems to be true for computers. Of course, if you exchange a computer for a computer, if you replace it with other electrical appliances, such as a washing machine, it will become 200. For example, if a new computer costs 5,000 and you replace it with an old computer, you will receive a subsidy of 400 yuan, but the actual cost is only 4,600 yuan. If you replace it with an old washing machine, you will receive a subsidy of 200 yuan; if the price of a new computer is 3,000 and you replace it with an old computer, then If 10% of the new price is less than the subsidy upper limit, you will receive a subsidy of 300 yuan. If you exchange an old washing machine, it will only be a subsidy of 200 yuan. This subsidy is issued by the state and has nothing to do with the store (you cannot trade in the old for new when shopping online). Generally, Suning, Gome, Dazhong and Dazhong can do it, but the trade-in requirements are different. This activity lasts until June 1, 2010. The pilot cities include Beijing, Shanghai, etc., and local household registration must be purchased locally. The purpose is to boost national consumption levels. The other is to send home appliances to the countryside, which requires you to have an agricultural registered permanent residence, and you are not just randomly selected, but several types of electrical appliances are designated for you to choose from.
