In supply and demand theory, when the product supply number is more than the consumer demand number, then it will cause the product's price to be fallen down. So, such as cigarette case, when U.S. government subsidizes fund to assist U.S. cigarette manufacturer to develop their cigarette business to encourage them to reserch different kinds taste of cigarette to grow in non-farming industry. It will lead many cigarette manufacturers compete in U.S. domestic market. Moreover, due to different kinds of U.S. cigarette supply number is more than U.S. domestic cigarette buyer number. Hence, it will cause U.S. domestic cigarette sellers to reduce cigarette sale price in order to attract many cigarette conumers to choose to buy themselves brand of cigarette to smoke. Hence, U.S.'s domestic cigarette supply number is more than cigarette consumer demand number.This factor will also lead U.S. domestic cigarette manufacturers to choose to reduce themselves cigarette price in order to attract many cigarette consumers to choose to buy themselves brand of cigarette to smoke. Hence, U.S. cigarette consumer individual behavior will influence cigarette industry economic growth. It is depending on whether how many U.S. cigarette consumers accept to smoke cigarette if many U.S. cigarette consumers feel it is not helth product to influence their health to be worse when they had been smoking long term. Then, the U.S. cigarette economic development will be poor. So, U.S. domestic cigarette consumer' health attitudes will influence their cigarette purchase behaviors. It implies that if many U.S. cigarette consumers consider their health, then the U.S.cigarette consumers number will be decreased to influence U.S. cigarette industry income will be also decreased. Although, U.S. government can spend money to subsidize cigarette manufacturers to develop their cigarette manufacturing industry. But it is not represent the cigarette manufacturers can succeed to raise to sell their cigarette number. Because U.S. domestic cigarette consumer individual health attitude will influence U.S. cigarette sale number, even they are good taste and famous brand and cheap price factor.Every U.S. cigeratte manufacturers choose to sell extra many cigarettes to overseas market. But, it is not guaranty to sell more easily. Because if overseas cigarette consumers feel cigarette product can bring harm to influence their health when they smoke long time. Then, their negative attitude to smoke cigarette which will influence they choose not to buy any brands of U.S. cigarettes to smoke. Even, cheap price, famous brand, good taste factor, they can not attract them to buy. So, cigarette consumers' negative or positive smoking cigarette feeling or attitude factor which will influence cigarette consumers to choose to buy any brands of U.S. cigarette to smoke. Consequently, I conclude that how to change global cigarette consumers to positive smoking attitude or feeling from negative cigarette smoking feeling or attitude, that is one important factor to lead U.S. cigarette industry in success.
