中国养老金区域不平等的演化格局与驱动机理研究

随着中国社会养老保险实现了制度全覆盖，养老金的主要矛盾已从“是否拥有”转变为了“是否公平”。针对中国养老金区域不平等的突出问题，本项目遵循“演化格局—驱动机理—实证检验—政策建议”的研究思路，首先，对中国养老金区域不平等进行多维测度，描绘其演化格局，总结其演化特征和规律；其次，采用交叉学科分析方法构建“2+5+4”理论分析框架，深入剖析养老金区域不平等背后的驱动机理；再次，构建实证模型对驱动机理进行检验，厘清其中的因果关系和贡献大小，并分解出中国养老金区域不平等的合理部分与不合理部分；最后，建立系统动力学仿真模型，对缩小中国养老金区域不平等的相关政策进行模拟，并据此提出具体的优化路径和对策建议。研究将推动经济地理学、社会学、人口学和计量经济学等交叉学科理论的创新，破解养老金“区域分割”的制度困境，为缩小养老金区域不平等、促进区域均衡发展提供指导和借鉴。

As China's social pension insurance has achieved full coverage of the system, the main contradiction of pension has changed from "whether it is owned" to "whether it is fair." In response to the prominent problem of regional inequality in China’s pension, this project follows the research idea of “evolutionary pattern—driving mechanism—empirical test—policy recommendations”. Firstly, carry out a multi-dimensional measurement of regional inequality in China's pension, describe its evolution pattern, and summarize its evolution characteristics and laws. Secondly, using interdisciplinary analysis methods to construct the "2+5+4" theoretical analysis framework, in-depth analysis of the driving mechanism of pension regional inequality. Thirdly, construct an empirical model to test the driving mechanism, clarify the causal relationship and contribution, and decompose the reasonable and unreasonable parts of regional inequality in China's pension. Finally, a system dynamics simulation model is established to simulate the relevant policies for reducing pension regional inequality in China, and based on this, specific optimization paths and countermeasures are proposed. This research will promote the innovation of cross-disciplinary theories such as economic geography, sociology, demography, and econometrics. It helps to solve the system dilemma of pension "regional segmentation", and provide guidance and reference for reducing regional inequality in pension and promoting balanced regional development.
