Abstract From the two dimensions of digital industrialization and industrial digitization, this paper explored the mechanism of quality change, efficiency change and power change promoted by digital technology in the economic and social development.In the paper, 44 cities in the Yangtze River Economic Belt were selected as samples. On the basis of measuring the development level of digital technology by using entropy weight method, this paper empirically tested the situation of transformation and upgrading driven by digital technology in sample cities from 2004 to 2019 by constructing PVAR model . The results show that digital technology and economic transformation and upgrading have inertia，and digital technology is an important factor that affect regional economic transformation and upgrading. Its driving effect has certain regional heterogeneity, and it has a stable promoting effect on the midstream cities, but the engine effect on the economic transformation and upgrading of the upstream and downstream cities is not obvious, and even has a short-term inhibiting effect. Therefore, in order to enhance the level of digital technology and give full play to its role in driving regional economic transformation and upgrading, it is necessary to deepen digital industrialization, strengthen industrial digitization, optimize the talent strategic system, and refine the regional development strategy .
