Abstract: Using the DEA-Tobit two-stage method, this present paper studies the input-output efficiency of large-scale stadiums in 31 provinces, cities and autonomous regions in China (excluding Hong Kong, Macao and Taiwan) with the date from the sixth National Sports Field Census. The results show that: (1) there is no significant difference in comprehensive technical efficiency among the eastern, central and western regions of China, and it is effective only in 11 provinces, municipal cities and autonomous regions; (2) there is no significant difference in pure technical efficiency among the eastern, central and western regions of China, and it is effective only in 13 provinces, municipal cities and autonomous regions; (3) there is no significant difference in scale efficiency among the eastern, central and western regions of China and it is effective only in 12 provinces, municipal cities and autonomous regions; (4) the output shortage rate of large-scale stadiums in China is significantly higher than input redundancy rate and the input redundancy rate and output deficiency rate in the eastern regions are significantly higher than that in the central and western regions; (5) 12 provinces, municipal cities and autonomous regions are in the stage of decreasing scale efficiency while 7 provinces, municipal cities and autonomous regions are in the stage of increasing scale efficiency. The conclusions are as follows: (1) the regional differences of input-output comprehensive technical efficiency, pure technical efficiency and scale efficiency of large-scale stadiums in China are not significant, but they are all "high in the West and low in the East"; (2) the reasons for the low comprehensive technical efficiency of input-output of large-scale stadiums in China are mainly due to the low allocation and utilization level of input-output resources of large-scale stadiums; (3) the input redundancy and output insufficiency of large-scale stadiums in developed areas coexist, and both are higher than those in central and western areas; (4) regional economic development level, government will, urbanization, geographical location and human resources inhibit the input-output efficiency of large-scale stadiums in various degrees; only population density can comprehensively improve the input-output efficiency of large-scale stadiums.
