The impact of price changes on consumer demand, the impact of price changes on basic necessities and high-end durable demand, and the impact of price changes on production [learning at hard points], the impact of price changes on prices and supply and demand [learning process], self-learning 1. Impact of price changes on people's lives: generally, when the price of a commodity rises, people buy it; when the price of such commodity falls, the effect on demand of its purchase (2) price changes: price movements cause demand changes, but demand for different commodities has a smaller impact on demand, and demand has a greater impact on demand (3) commodity prices: consumer demand for a given commodity is affected not only by the commodity but also by the rise of one commodity in one commodity in one commodity in another commodity, leading to a decline in one commodity in another commodity。

Of the commodities for which there is , the price of one commodity increases not only for that commodity, but also for another commodity, and vice versa, the decline in the price of one commodity and the increase in demand will give rise to the impact on production operations of another commodity: regulation when the price of one factor falls, the producer will ; and the increase in the price of factors of production will lead the producer to the effect of price changes on production is an important reflection of classroom exploration: based on your life experience, answer the following questions: (1) in your daily life, which commodities are purchased during the boom and which are bought during the light season? What are the reasons? (2) is it true that there are no “good and cheap” goods in the market, as the saying goes: “if there is no good or good”? (3) what are the implications for food and silver jewellery, respectively, when prices change? In the case of mr. Kao, whose home is more than 10 kilometres from the school, he wants to buy a vehicle to facilitate his work - a motorcycle or electric car - the situation was as follows: (1) the price of petrol rose to 8. 0 yuan/l, and there was an upward trend (2) the price of electricity was 0. 56 yuan/degree (3), which is calculated to be 2. 2 litres per 100 kilometres of motorcycle and 6 degrees of electric power。
In the above-mentioned case, (1) which two commodities are alternatives to each other? Which two are complementary? (2) students are invited to give their advice to mr. Kao on how to calculate the means of transportation, justifying the extension 1. Different commodities respond to price changes to varying degrees (demand elasticity theory): the response of different commodities to price movements is that the impact of different price movements on the demand for basic necessities is relatively small, and the impact on demand for high-end durables is as much greater as shown in figure 1 of the “demand curve”, which shows that demand for aluminum commodities increases much smaller than that of a commodity, as compared to that commodity, which reflects the demand curve for essentials, and figure 2 reflects the demand curve for consumer durables, which is the demand elasticity theory. In general, price and supply changes are positive, as shown in figure 3 of the “supply curve”, where the supply of commodities is increased with the rise in the price of the commodity. 3. Mr. Li, who works in jenan, was prepared to buy a toyota car, but had to give up because the price of gasoline had been rising in recent years。

The recent reduction in the price of gasoline, which he intends to purchase in mid-autumn, is due to the fact that automobiles and gasoline () a. Have different utility values. C. Are complementary commodity d. Are alternative to each other. The approach followed by traders in their promotions: in order for consumers to buy more of their own commodities, often lower the unit price of the commodity suggests that (a) a. Lower commodity prices can increase their sales volume b. Lower the value of the goods can increase their sales volume. C. Cost reduction is an important means of market competition for commercials. D. Cost reduction is an important means of autonomous learning for merchants with reference answers to market competition. 1. (1) reduction in the level of responsiveness, (2) increase in the price of high-end durable goods, and shift in the prices of related commodity prices, increasing demand; reduction in demand, resulting in reduced demand; increase in demand by 2。
