现有关于民主与经济发展关系研究的文献，主要集中在民主与增长方面。 然而，关于民主对经济发展的其他因素如投资、消费、腐败、不平等和幸福等影响的研究相对较少。本项目采用随机动态规划与计量相结合的方法，研究政治制度对经济发展影响的动态随机一般均衡机制与实效，研究内容和创新主要包括：（1）使用动态随机一般均衡的方法，构建政治制度影响经济增长的理论机制；（2）基于166个国家和地区的面板数据，使用混合OLS、 固定效应、随机效应、动态Arellano - Bond GMM估计和2SLS工具变量法，重点检验民主与收入的交互作用对投资、消费、增长、收入不平等、腐败、幸福等经济变量的影响；（3）比较分析民主制度在不同经济发展程度国家的历史经验与实效，并提出政策建议。研究可以帮助我们进一步认识民主与威权制度的优势与不足，为建设有中国特色的社会主义民主与市场经济，为我国未来经济社会持续健康稳定发展提供参考。

Existing New Political Economy literature which in terms of democracy and economic development are mainly focus on the relationship between democracy and growth. However, the discussing such as the influence of democracy on investment, consumption, corruption, inequality and happiness are relatively few. Based on the Panel Data of 166 countries and territories , this study uses a combination of theoretical and empirical research methods, by building a DSGE(Dynamic Stochastic General Equilibrium) model between political regime and economic growth, we will use the Pooled OLS, Fixed Effects, Random Effects, Dynamic Arellano - Bond GMM and 2SLS instrumental variable methods to test the effect of political regime on investment, consumption, growth, income inequality, corruption, happiness and other economic factors. According to this empirical research, we can further understand the advantages and disadvantages of democracy and non-democracy regime, which will provide a new perspective for the New Political Economics and provide a better guidance and reference for the future stability and development of our economy and society. Besides, this study involving multiple disciplines and fields, such as Political Science, Statistics, Public Economics, Development Economics, Dynamic Economics, Econometrics and so on, which would help to promote the development of multi-disciplinary integration.
