Abstract：In recent years, digital economy with “the Internet plus” at the core has been developing rapidly in China, which has greatly improved China’s economic quality and driven sustainable development of national economy. Digital economy develops rapidly and achieves corner overtaking as it depends on China’s consumption dividends of big population and is making sweeping changes in traditional economic model. From perspective of microeconomics, digital economy integrates “economy of scale” and “economy of scope” and it is changing traditional profit models. From the perspective of meso-economics, with mechanism innovation, digital economy has changed the market structure and thus made both buyers and sellers trade in an almost perfect competitive market. From the perspective of macroeconomics, digital economy is pushing the boundary on the economic plans to allocate resources so as to strengthen integration between government and market. These changes call for the government to keep up with innovation, provide quality public service, narrow digital divides, and advocate digital ethics.
