参数异质性、财政分权与区域经济增长的不平衡性

现有有关经济增长与财政分权的文献均假设两者之间关系为线性关系，而本文的研究却发现，财政分权与省级经济增长之间的关系为非线性关系，具有显著的门槛临界值效果。利用中国1980-2004年28个省市自治区的面板数据，运用非动态的面板门槛模型、非线性最小二乘法（NLS）和仿真试验，本文的研究结果表明，财政分权对区域经济增长的影响具有不平衡性，其影响力度因人均资本增长率的差异而有所不同。当人均资本增长率小于0.1707时，财政分权对经济增长的贡献力为0.1211；当人均资本增长率处于第二区间时，财政分权对经济增长率的影响大小为0.1925；而一旦人均资本增长率处于高区间时（大于0.2909），财政分权的影响力度变为0.2731。

Parameter Heterogeneity,Fiscal Decentralization and Non-balance of Regional Economic Growth

Recent studies examining the relationship of fiscal decentralization and economic growth all hypothesize that the relationship is linear,but in this paper we find that the relationship between them is nonlinear.Using 28 provinces panel data over the periods of 1980 to 2004,we find fiscal decentralization generally promotes regional economic growth,but its impact on regional economic growth is limited to the growth rate of per capita capital.When the growth rate of per capita capital is lower than 0.1707,the...
