罗默模型——对电子商务发展的理论分析（Romer Model -- a theoretical analysis of the development of e-commerce） Romers endogenous growth theory argues that new knowledge created by firms is a major factor in economic growth. As a special factor of production, knowledge itself has diminishing returns, while in production it has increasing returns. In addition, knowledge also has externalities, that is, the knowledge created by an enterprise will become public knowledge and benefit other enterprises.

It can be seen that the current development characteristics of e-commerce should prove the hypothesis of the Romer model. In e-commerce, the increase of each enterprise caused by the investment of the capital stock will lead to a corresponding rise in the stock of knowledge, because the knowledge spillover effect, the new capital of each enterprise on the accumulation of capital production of other enterprises have made a contribution. So, as the model predicts, e-commerce will lead to long-term growth across the economy. First, the new growth model Romers endogenous growth theory In the last half century, the modern economic growth theory has experienced a path from exogenous growth to endogenous growth. In Romer (Romer), Lucas (Lucas), as the representative of a group of economists, based on rethinking of the neo classical growth theory, put forward a set of endogenous technological progress as the main content of the thesis, discusses the prospects for long-term economic growth, opening up a new growth theory (New Growth Theory) on the trend of . The new growth theory seeks to address an important and perplexing subject in economic science: the root cause of growth. It is characterized by a significant emphasis on economic growth, not external forces (such as exogenous technological change), but the economic system of internal forces (such as the internal tec
