社会资本、交易成本与经济增长

Social Capital,Transaction Costs and Economic Growth

社会资本作为传统资本的必要补充部分,理应在推动实现经济高质量发展的过程中发挥重要的作用。本文构建了一个社会资本内生化的经济增长模型,探究社会资本对经济增长的影响并揭示了社会资本促进经济增长的作用机制。研究发现:在不考虑技术内生且其增长率为零的条件下,长期经济增长速率主要由社会资本和实物资本两者的增长率所决定;市场交易成本与社会资本水平存在负向关系,社会资本水平越高,越能有效降低市场交易成本;经济体面临外部技术冲击时,均衡增长率和均衡交易成本的变化取决于社会资本水平且因社会资本水平的不同表现出较大差异;社会资本水平对交易成本的影响呈现“门槛效应”。本文创新性地构建了社会资本的动态演化方程,在技术内生化的基础上分析社会资本对经济增长的影响,揭示了社会资本与经济增长之间的关系,丰富并完善了社会资本与经济增长的理论研究。

Social capital,as an essential complement to traditional capital,should play a more significant role in promoting high-quality economic development.This paper constructs an endogenous economic growth model with social capital,explores the impact of social capital on economic growth,and reveals the mechanism through which social capital promotes economic growth.The research findings indicate that,under the assumption of no endogenous technological growth with a growth rate of zero,the long-term economic growth rate is mainly determined by the growth rates of both social capital and physical capital.Market transaction costs are negatively related to the level of social capital,with higher levels of social capital effectively reducing market transaction costs.When facing extermal technological shocks,the changes in equilibrium growth rate and equilibrium transaction costs depend on the level of social capital,showing significant differences due to varying levels of social capital.The impact of social capital on transaction costs exhibits a“threshold effect.”This paper innovatively constructs a dynamic evolution equation for social capital and analyzes the impact of social capital on economic growth based on endogenous technological growth,revealing the relationship between social capital and economic growth,and enriching and improving the theoretical research on social capital and economic growth.
