Abstract

Since the introduction of the "New Normal" in 2012, China’s economic development has gradually shifted toward high-quality growth. By 2023, the tertiary sector accounted for 54.6% of GDP, becoming the main driver of economic expansion. However, emerging industries still require government guidance to ensure orderly development. Based on panel data from multiple industries spanning 1990 to 2023, this paper constructs an industrial network graph and employs multiple regression models to systematically analyze inter-industry linkages, marginal contributions to GDP, and investment spillover effects. The study reveals that when the government prioritizes GDP growth alone, mechanical manufacturing receives the highest investment; when both GDP growth and social equity and environmental sustainability are considered, agriculture receives more investment; and when GDP growth, unemployment, social equity, and environmental sustainability are jointly considered, IT services become the top investment choice.
