Abstract (2. Language):
Purpose: This paper is committed to design a logistics industry development policy model
based on system dynamic to simulate the policy measures which promote region economic and
logistics efficiency. The interaction between logistic industry development policy and economy
needs to be investigated and the influence degree of logistic efficiency affected by industry
policy needs to be identified too.
Design/methodology/approach: In order to achieve the objective, it makes a system analysis
from industry perspective to divide system into economic growth subsystem, logistics demand
subsystem and logistics supply subsystem. Then the hypothesis and the boundaries are defined,
and the causal diagram and system flow diagrams are drawn. The paper designs parameters and
structural equation by the sample of Beijing using the econometrics model and takes model
validation. Taking Beijing as an example, logistics industry development policy is simulated
from the aspect of technological progress, increasing fixed assets investment, adjusting the
industrial structure proportion and comprehensive policy by changing the parameters using
Vensim-PLE.
Findings: After logistics development policy is highly simulated by system dynamic model of
logistics industry development policy, it is found that the policies of technological progress,
fixed assets investment increasing, the industrial structure proportion adjustment and the comprehensive policy have different function to affect GDP, logistics demand, supply capacity
and actual logistics costs.
Originality/value: Compared with the previous research, this paper analyzes the interactive
mechanism between logistics industry policy and region economy from a system perspective
and establishes system dynamics model of logistics industry development policy to make up for
the limitation of previous research.
