Reflection

After reading through Alfred Marshall's great work Principles of Economics, thinking about some basic concepts of economics, first of all, starting from the origin, explore some essential concepts of economics.In the social context of that time, the author's understanding of the main work of economists was to discover how potential social assets could be developed and how they could be most wisely utilized, in conjunction with modern economic development and personal learning. Regarding the essence of economics, the individual's view is that the so-called economics refers to, under limited natural and non natural resource conditions, A social science that studies how to maximize resource utilization and achieve optimal wealth. The main work of contemporary economists should be to research and develop existing theories, based on practical situations, in order to develop economic theories that can be applied to and combined with contemporary economic development. As stated in the book, for economists, there are three types of intelligence that are most important: perception, imagination, and reasoning. Economists need to have a perception to be good at discovering the extraordinary in visible events in life; At the same time, be able to have imagination to explore these extraordinary reasons and results that lie beneath the surface; Reasoning, on the other hand, enables economists to derive universal principles that can be applied to ordinary cases from special examples after exploring and thinking. From the above, we can see that economics is a science that studies wealth.
