经济增长目标设定与地方债务规模扩张——基于逐顶竞争的视角

地方经济增长目标的行为特征和影响研究已有很多,但探讨城市之间地方经济增长目标设定的横向竞争策略及其债务扩张效应的研究仍然匮乏.文章构建数理模型论证了在兼顾绩效收益和风险成本的综合考量下,完全对称的纯策略纳什均衡博弈将促使地方政府经济增长目标设定同时存在逐底竞争动机和逐顶竞争动机,且以逐顶竞争动机为主.通过改进空间权重矩阵,文章基于2005-2018年城市面板数据构建非对称反应模型进行了地方经济增长目标设定的空间分解,验证并量化了逐顶竞争效应.进一步匹配地方融资平台债务融资数据的回归分析显示,省内城市间经济增长目标逐顶竞争会显著推高地方融资平台的城投债融资概率和融资规模,以信托融资为主的非标债务融资虽然没有受到显著影响,但非标债务融资的担保圈形成概率显著提高,从而助长了区域性、系统性财政金融风险.文章指出了在自上而下的纵向"层层加码"以外,同级政府之间横向逐顶竞争也是造成经济增长目标居高不下的根源,进而通过基建压力向隐性债务风险传导,这一结论为未来进一步优化绩效考核、推动经济高质量发展指明了改进方向.
Economic Growth Target Setting and Local Debt Expansion:From the Perspective of Racing-to-the-top Competition
There are many researches on the behavior characteristics and influences of local economic growth target(hereafter EGT for short),but researches on horizontal competition strategy of setting EGT as well as its debt expansion effect are still scarce.In this paper,a mathematical model comprehensively considering performance benefit and risk cost is constructed to demonstrate that,the completely symmetric pure strategy Nash equilibrium game will promote the local government's EGT setting with both racing-to-the-bottom and racing-to-the-top motivation,and the latter motivation prevails.By improving the traditional spatial weight matrix,an asymmetric response model is constructed to accurately decompose these two opposite motivations.Based on the urban panel data from 2005 to 2018,the racing-to-the-top motivation is verified and measured.The regression analysis further matching the debt financing data of local financing platforms show that the racing-to-the-top effect among cities in the province will significantly increase the probability and scale of municipal investment bond.Al-though the non-standard debt financing dominated by governmental trust is not significantly affected,the formation probabili-ty of its guarantee circle seems significantly increased,which might contribute to regional and systemic fiscal and financial risks.This paper suggests that in addition to the top-down vertical amplification,horizontal competition among governments is another root cause of the high EGT,and thus pressing infrastructure construction to the hidden debt risk transmission.The conclusion points out the improvement direction for further optimization of performance assessment and further promotion of high-quality economic development in the future.
