This study aims to examine the impact of Internet development on the urban-rural income gap in China. By using a provincial level panel dataset comprising 31 of China’s provinces, it analyzes and compares the effects of the eastern, central, and western regions over the period of 2005–2016. The results show that Internet development aggravates the gap in the central region much more than that in the eastern and western regions. The trade openness expands the urban-rural income gap only in the eastern region. Urbanization reduces the urban-rural income gap in the western region more than that in the eastern and central regions. Additionally, the regional economic development level also reduces the urban-rural income gap in central region more than that in the eastern region. FDI reduces the urban-rural income gap only in the central region. Additionally, while the urban-rural income gap can widen further by Internet development with trade openness, it can be decreased if Internet development is combined with FDI and urbanization. To reduce urban-rural income gap, the government should accelerate the construction of Internet according to regional differences.

In today’s integrated economy, no country’s economic development can be outside the international economic environment. After continuous and rapid development, China’s economy has surpassed Japan’s overall economic level and has become the second largest economic power in the world. But with the advent of the new normal economy in China, the economy has entered a stage of medium- and high-speed development, and business management and cost management of enterprises are also facing the transformation of strategies and systems. Every enterprise and company is trying its best to improve its own cost management system, business model, and cost management strategy. The development of science and technology and the advent of the era of information technology have gradually brought China’s economic development into a green development track, which has put forward greater research topics for enterprise cost management. Therefore, the method for controlling economic management cost in enterprises based on the Coase theorem was proposed.
