基于中间投入品种类扩张的水平创新型内生增长模型,本文论证了金融发展影响-国长期经济增长的作用机制。对平衡增长路径的稳态增长率求解结果表明,稳态消费、产出增长率同时取决于研发、人力资本以及金融部门的产出效率;进一步比较静态分析表明较高的金融发展水平将提高稳态消费增长率,然而各产出效率参数对金融部门自身的稳态增长率影响是不确定的。
We extend the endogenous growth model with horizontal innovations to construct a five-sector growth model in which a financial sector is introduced. In this set-up, the solution in the balanced growth path shows that steady state consumption and output growth rate essentially depend on the productivity in R~D sector, human capital sector as well as financial sector. The further comparative static analysis demonstrates that more efficient financial system leads to higher steady state growth rate, but the effects of productivity in other sectors on financial sector are uncertain.
