中国农村地区收入分布的静态趋同和动态演化研究,采用核密度估计及Silverman多众数检验法,考察1989—2007年地区收入分布的集聚状况,未发现统计上显著的"双峰"趋同,但分布的集聚状况存在明显的演化趋势。因素分析表明:(1)工资性收入和家庭经营性收入变动促使在1993—1998年出现了"单峰"趋向"双峰"再回"单峰"的演化历程,其中家庭经营性收入变动在前一阶段推动"双峰化",后又促使分布回到"单峰",而工资性收入变动始终阻碍收入分布趋向"双峰";(2)工资性收入变动是中国农村地区收入分布近十年来未趋向"两俱乐部"的主要原因,进一步将其影响分解为分配效应和增长效应后发现,各地平均工资的增长是始终维持"单一俱乐部"的关键。
中國農村地區收入分佈的靜態趨同和動態縯化研究,採用覈密度估計及Silverman多衆數檢驗法,攷察1989—2007年地區收入分佈的集聚狀況,未髮現統計上顯著的"雙峰"趨同,但分佈的集聚狀況存在明顯的縯化趨勢。因素分析錶明:(1)工資性收入和傢庭經營性收入變動促使在1993—1998年齣現瞭"單峰"趨嚮"雙峰"再迴"單峰"的縯化歷程,其中傢庭經營性收入變動在前一階段推動"雙峰化",後又促使分佈迴到"單峰",而工資性收入變動始終阻礙收入分佈趨嚮"雙峰";(2)工資性收入變動是中國農村地區收入分佈近十年來未趨嚮"兩俱樂部"的主要原因,進一步將其影響分解為分配效應和增長效應後髮現,各地平均工資的增長是始終維持"單一俱樂部"的關鍵。

This paper analyses the static convergence and dynamics of regional income distribution in rural China.The convergence of income distribution during 1989—2007 is examined by kernel density estimation and Silverman's multimodality test.It is found that there's no statistically significant ″twin peaks″ convergence in the regional income distribution.However,there exists a dynamic change in it.The results of factor analysis have the following two indications.First,between 1993 and 1998,the change of wage income and household business income resulted in the dynamic process of income distribution from ″single peak″ to ″twin peaks″,and back to ″single peak″ again.Especially,the change of household business income contributed to a ″twin peaks″ income distribution in the earlier stage and a ″single peak″ one in the later stage while the change of wage income always led to a ″single peak″ distribution.Second,the change of wage income had been the main driving force for maintaining ″singe peak″ distribution since 1999.The impact of wage income on the income distribution could be decomposed into a distributional effect and a growth effect,in which the latter,namely the growth of average regional income,was the key to maintaining the ″single peak″ income distribution in rural China.
