The Research On Operation Efficiency Of Endowment Insurance System For Urban And Rural Residents Based On Super-SBM Model

Although China’s current social security system is constantly improving,the related system reform of endowment security has made great achievements,the increasingly serious problem of aging population has posed a severe challenge to the endowment insurance system.In order to fully realize the security goal of providing for the elderly,break the boundary between urban and rural areas,promote the fairness of the system and realize the equality of pension rights,China officially merged the new rural insurance system and urban residents’ pension insurance into the basic pension insurance for urban and rural residents in 2014.This system development until now,still exist due to the security level is not high,the widening gap between urban and rural areas and the development of clear difference between regions,for the running efficiency of the system,the regional difference and influence factor analysis to optimize the policy system to improve the system operation quality,and the effect of critical theory significance and practical significance.Based on the super-efficiency SBM model,this paper studies the operating efficiency of the system by integrating the five indicators of income and expenditure of urban and rural residential insurance fund,fund balance,number of insured people and number of people actually receiving benefits in 31 inland provinces,cities and autonomous regions of China.Based on the efficiency results obtained,the Moran index was used to conduct global spatial autocorrelation analysis,and LISA cluster graph was used to analyze the dynamic changes of clustering situation in each region since the system merged.Finally,this paper studies the influencing factors of the operation efficiency of urban and rural housing insurance system through Tobit model.This paper draws the conclusions :(1)from the overall perspective,the operation efficiency of China’s urban and rural housing insurance system is relatively high,but there is still a large space for improvement.Only a small number of developed provinces have reached the traditional SBM efficiency,and the comprehensive efficiency of more than half provinces has not reached the national average level.(2)From the perspective of spatial and temporal pattern,the agglomeration effect of urban and rural residential protection development has been obvious since the integration of urban and rural areas,and the agglomeration degree of the high-efficiency area in the eastern China is gradually stable,but at the same time,there is a lack of radiation effect to the surrounding areas,lack of synergistic development;(3)From the perspective of influencing factors,per capita GDP,government size,aging population density,old-age dependency ratio and pension replacement rate have a significant impact on the comprehensive efficiency of the operation of urban and rural housing insurance system.Based on the above research results,this paper puts forward corresponding policy suggestions on how to improve the old-age insurance system for urban and rural residents and improve the operation efficiency of the system.
