Sismondi and Rochelle both mentioned that economics studies "people". But the concept of people they are talking about is rather vague. Masha, the pioneer of the subjective economic school, clearly pointed out in (Economic Harmony) that "the object of political economy is people" and explained that "desire, effort and satisfaction are people in the economic point of view". Austrian mengle clearly defined the research object of political economy as human desire and its satisfaction. He divided economics into applied economics, historical statistical economics and theoretical economics. He pointed out in "Principles of National Economics" that theoretical economics studies the conditions for human beings to carry out their pre-financing activities to satisfy their desires. Both Pombavik and Wiezell still regard human desire and its satisfaction as the research object of political economy. Jevons also pointed out that economics is the calculus of happiness and pain.
