丝绸之路经济带建设的区域差异化研究 ――基于可变交易成本的区域均衡模型
Regional Differential Research of the Silk Road Economic Belt Construction ―Based on a Regional Equilibrium Model with Variable Transaction Costs

对丝绸之路经济带涵盖的国家进行了区域划分，从不同层面深入分析了丝绸之路经济带所涵盖四大区域的不同特征。根据不同地区的经济特征差异，构建了交易成本可变的区域均衡模型。理论分析结果显示，我国进行丝绸之路经济带建设将有望通过国际贸易交易成本的降低，增强与丝绸之路经济带相关各区域的经济贸易联系。并进行了数值模拟，分析了不同情形下与各区域进行经贸合作的效果，对比实际贸易变化可以证实模拟结果具有一定的解释力。最后根据数值模拟结果，得出了若干启示。
Firstly, this paper divides the countries of the Silk Road Economic Belt into different regions and analyzes the features of the four main regions on the Belt. Then it builds a regional equilibrium model with variable transaction costs according to the differences among the four regions. The results of theoretical analysis show that Silk Road Economic Belt Construction will reduce the transaction costs of international trade and then enhance the economic links of these regions. After that, this paper analyzes the effect of regional economic and trade cooperation under different circumstances by numerical simulation method. The simulation results are confirmed by being compared with the actual trade changes. Finally, according to the simulation results, the paper gives some advices
