Title: The "Broadband China" Strategy, Total Factor Productivity and Resource Allocation Efficiency: From the Perspective of Industrial Linkages

Abstract: The construction of digital infrastructure, especially the popularization of broadband networks, has become the core driving force for China to promote industrial upgrading and achieve high-quality development in the era of digital economy. To accelerate this process, the State Council has launched the "Broadband China" Strategy since 2013. This paper takes A-share listed companies from 2010 to 2022 as samples to quantitatively estimate the growth rate of total factor productivity (TFP) of enterprises in the digital economy sector driven by the "Broadband China" Strategy. On this basis, combined with the 2017 China 149-sector input-output table, a production network model is constructed to analyze the impact of the TFP growth brought by this strategy on GDP, new industrial linkages, employment share of various sectors, economic resilience, and resource allocation efficiency. The research shows that the "Broadband China" Strategy not only significantly improves the TFP of enterprises in the digital economy sector and promotes GDP growth, but also gives birth to new backward industrial linkages, increases the labor share of the digital economy sector and enhances economic resilience; the strategy improves the marginal return of capital in various sectors and promotes the equalization of income distribution, but at the same time intensifies the structural contradiction of inter-sectoral resource misallocation; under the existing resource misallocation, the indirect treatment effect in the general equilibrium framework offsets part of the direct treatment effect of resource misallocation, driving the overall TFP growth by approximately 1.59%; counterfactual analysis shows that if the resource misallocation caused by the "Broadband China" Strategy is completely eliminated, the overall TFP can be further increased to 9.76%. Finally, this study puts forward corresponding policy suggestions on how to more effectively promote the improvement of total factor productivity, strengthen industrial digitalization and reduce inter-sectoral resource misallocation in the context of the in-depth integration of digital economy and real economy in China in the future.
