Abstract:  In the era of the digital economy, internet platforms, as a digital means of production with infrastructural properties, are the result of the synergistic interplay between the information technology revolution and changes in production relations.  Through the establishment and appropriation of internet platforms, platform capital reconstructs the mode of production. The spatial reconstruction mechanism of platform capital follows a dual logic of the spatialization of capital and the capitalization of space. On the one hand, platform capital, which performs multiple functions of capital, creates a new digital space that reflects an abstract form of spatial power and spatial order based on new economic relations, originating essentially from the reproduction of production relations maintained by capital expansion. On the other hand, digital space gives rise to novel forms of rent and becomes a sphere of circulation for interestbearing capital, which is incorporated into the proliferation process of platform capital, exacerbating underlying crises such as spatial injustice. This paper elucidates that the reconstruction of digital space is a product of the movement and proliferation of platform capital, thereby further clarifying the forms of capital, sources of profit, and accumulation models of platform capital. It aims to apply the conceptual potential of spatial production theory to the theoretical analysis and practical governance of platform capital, in order to guide and regulate the healthy and sustainable development of the platform economy.

Key words: platform capital, internet platform, spatial production, capital accumulation
