Problems solved by technology
[0004] The technical problem to be solved by the present invention is to propose an industrial agglomeration spatial layout simulation optimization screening method to solve the dynamic simulation problem of regional industrial geographical agglomeration in reality
The present invention adds geographic space to the theoretical model of spatial location for simulation, and uses the Monte Carlo spatial statistical method to evaluate the reliability of the simulation results to solve the randomness problem of dynamic simulation of industrial geographic agglomeration
Then, the empirical orthogonal function is used to select the optimization model of industrial agglomeration space layout from a set of simulation results that have passed the reliability evaluation, so as to solve the uncertainty problem of dynamic simulation of regional industrial geographical agglomeration

The invention provides an industry cluster space layout simulation, optimization and screening method, which comprises the steps of firstly generating a geographic space simulation field, introducing the geographic space simulation field into a space location theoretical model and establishing an industry geographic cluster model; then performing reliability assessment to industry geographic cluster simulation by adopting a Monto Carlo spatial statistic test method; finally screening out an industry cluster space layout optimization mode from a group of simulation results by adopting an empirical orthogonal function. The industry cluster space layout simulation, optimization and screening method provided by the invention has the advantages that since the lack of geographic spaces in the space location theoretical model is defined, the randomness of the industry geographic cluster simulation is eliminated, the problem of uncertainty in the industry geographic cluster simulation is solved, the screened regional industry cluster space layout optimization mode is guaranteed to have stronger robustness and a basis of scientific decision making is provided for regional industry planning and sustainable development.
Description
technical field [0001] The invention relates to the technical field of regional industrial planning, in particular to a method for simulating, optimizing and screening industrial agglomeration space layout. Background technique [0002] In today's era of economic globalization and regionalization, industrial agglomeration shows a high degree of complexity and diversity. As a spatial organization model, industrial agglomeration plays a vital role in technological innovation and the improvement of production efficiency. Therefore, it has received extensive attention from scholars in related fields, and has increasingly become the focus and hotspot of contemporary interdisciplinary research. Under the new situation, my country's future regional economic growth model needs to study the evolution law of industrial spatial layout, the relationship between regional economic development and urbanization, and the regional impact of multinational enterprise agglomeration, so as to pro...
