Wealth of Nations 

The Wealth of Nations»s formerly name is The Study of the Nature and Causes of National Wealth and is the representative work of Adam Smith, the father of modern economics which is known as the "Great Economic Work of the First System". In the book, Adam Simy summed up the experience of the development of capitalist countries in the early modern times and criticized the important economic theory at that time. He made a systematic description of the movement process of the whole national economy, established a complete framework for economics, and laid a theoretical foundation for the capitalist free economy. For the first time, he proposed the theory that the market economy would be self-regulated by the "invisible hand". The publication of the book has become the starting point of the study of modern political economics, making economics an independent science. "The Wealth of the Nations" is a masterpiece of economics in any time by the economists.
