Analysis on the optimal path of economy-energy system in Fujian province based on SD model

In response to the national "13th five-year plan", Fujian province needs to make macro control of the economy-energy system. In this paper, with the help of SD model of system dynamics, the technical progress and industrial transformation were analyzed in a unified framework. According to the present situation of industrial structure and energy structure in Fujian province, the GDP and energy consumption in 2019-2025 were predicted. Industrial adjustment parameters and technical improvement parameters were set according to the national macro-control objectives, and the scenario under the corresponding optimization path was set with different optimization objectives. The conclusion that technological progress and energy consumption change, industrial structure optimization and economic development had the same trend of change was obtained through comprehensive analysis, which provided quantitative reference and decision-making basis for industrial transformation policy and the direction of technological innovation development.
