How applying demand and supply theory to explain computer industry consumer behaviorIn future computer industry, China laptop and desktop computer consumers will be global computer market main leader. I believe the reason is not because China has high population, it is due to Chinese students or working people or employers begin to feel laptop or desktop computers will help them to solve any learning or working aspect challenges in their daily live. The economic problem is computer material production number is decreasing, but global computer buyers number is also increasing. So, it will bring computer shortage to Chinese, it may due to Chinese population number is increasing and their computer needs are also increasing. But, global laptop and desktop manufacture supply number can not achieve enough number to satisfy Chinese computer buyers' needs. - sometimes called the basic or central economic problem - asserts that an economy's finite computer material production resource resources are insufficient to satisfy all different countries computer buyers wants and needs. Economics involves the study of how to allocate computer material production resources in conditions of scarcity to satisfy global computer laptop or desktop buyers' needs, such as office workers or students buyers. However, viewing economics as the study of how society allocates computer material production resources can lead to conflation of normative economic planning and empirical study of how economic agents operate in these global desktop or laptop buyers' need conditions.In mainstream neoclassical economics, it is assumed that humans pursue their self-interest, such as global laptop or desktop computer users often need to raise old style of computer functions to satisfy their unlimited computer function needs and that the market mechanism best satisfies the various wants different individuals might have. These wants are often divided into individual wants (which depend on the individual's preferences and purchasing power parity) and collective wants (which are the wants of entire groups of people, such as students or working people laptop or desktop users). Things such as food and clothing can be classified as either wants or needs, depending on what type and how often a good is requested. However, food and clothing is cheap and they may be essential products. So, consumers won't reduce their purchase number easily, if their prices are increased. Otherwise, computer consumers will be influenced their making decision to buy any kinds of computer easily, if the brand of computer increases its laptop or desktop price much suddenly. Such as China laptop or desktop consumers behavior, whether they will be influenced to change decision to buy the brand of computer if it's price is increased much suddenly. It depend on whether the China computer buyer feel good or bad quality and function to the brand computer. If he feels that the brand of computer quality and function is the best among other brands of computer. Then, the Chinese won't be influenced to choose to buy the brand of computer easily. Moreover, if the computer shop tells the China laptop or desktop buyer, he won't buy the brand of computer tomorrow easily because it has no any stock in the week. Then, the China computer buyer will still choose to buy this brand computer, even it increases price. So, in computer case, it does not represent the brand of computer can not sold easily if it increased its price, it depends on whether the buyer's good or bad or confidence feeling to it.
