The book discusses, elaborates on and answers questions to the following points:  Firstly, what has changed through the information technology represented by software, Internet and big data? How do these changes effect the production relationships, the production mode and the industrial development model? Can China realize a "great-leap-forward" in economic development by promoting such a new Internet economy?  Secondly, what is the format shown by the Internet economy? Is the Internet economy a market economy, or a planned economy, or is it an economic complex format which combines the planned economy and the market economy? What is the structure of the future economy? Which entities will compete with each other throughout the industries? What is the format of the future financial investment industry? Why does the Internet economy have a revolutionary impact on the economic base and the superstructure?  Thirdly, let us look back on the traditional manufacturing industry. What on earth is the core value of the manufacturing industry? How is the core technology and core value of manufacturing realized? Why can it be that the industrial Internet will become a rare historical opportunity for China's manufacturing industry and economy to achieve a "great-leap-forward" development?  Finally, in the big economic tide of Internet and big data, what are the future variables of China’s economy? What is the established economic policy of the United States for the global economy and industries? How should the economic variables of the United States be best dealt with, those that are determined as “US priority” and “the return of manufacturing industry” strongly promoted by the U.S. President Trump?
