Abstract: The upgrading of information technology has cultivated the new style of information industry, improved the innovation efficiency of the whole society and spawned digital economy. Aimed at the characteristics of the increasing development gap between the southern and northern regions presented by the spatial pattern of digital economy of China, taking the“Opinions of the State Council on Promoting Innovation and Development of Cloud Computing and Cultivating New Forms of Information Industry”as the policy evaluation object, and combined with the data of digital industry development of 62 cities from 2010 to 2019, this paper employs the PSM-DID method to measure the effect of policy implementation on the spatial pattern of digital economy in China from the three aspects: the degree of production factor agglomeration, the scale of digital industrialization, and the level of digital industrial value. It also employs the“core-periphery”theory of spatial economics to analyze the inner mechanism of the evolution of spatial pattern of China's digital economy. The findings show that the implementation of the policy has accelerated the regional agglomeration of the three production factors of digital industry: human resources, capitals and lands. The scale of the regional digital industrialization has also been expanded, while no significant influence is found on the promotion of the level of industrial contribution and the level of industrial value of the regional data factor. Meanwhile, there is regional heterogeneity in the net effect of the policy implementation; the promoting effect of the policy implementation on the agglomeration of production factors and the expansion of industrial scale is obviously greater in the southern region than that in the northern region.

Key words: new forms of information industry, double difference, spatial pattern of digital economy
