Based on the per capita net income indicator of peasants and the data of 31 755 town research units in China which were collected in 2016,the spatial pattern of China's town scale economy was analyzed by using methods including coefficient of variation,spatial classification,spatial interpolation,and spatial autocorrelation,and influencing factors were analyzed by geographic weighted regression and other methods. The results were as follows. 1) From the perspective of internal differences,the four major economic partitions were in order Northeast >West > Eastern > Central; the provincial level pattern showed the northwestern provinces were largest,the central and northeast provinces were relatively larger,the eastern coastal provinces were common,and the southwest were very small. The highest-value and higher-value areas at the city level showed the characteristics of "two core high-level cluster areas + a relatively concentrated area + speckle distribution",and the lower- value and lowest- value areas were continuously distributed. The pattern of county level was further refined than the city level,and the highest-value areas were mainly distributed in the southwest at this level. 2) From spatial distribution pattern,it was similar to the existing research conclusions,but the internal refinement and fragmentation were obvious. The highest-value and higher-value areas were mainly prominent in the core cities of Jiangsu,Zhejiang and some cities around Xinjiang and Inner Mongolia and are scattered in the central region. The low-value areas were continuously distributed in Central China,West China,Southwest China,and Northeast China,the high-value areas showed a decreasing trend from east to west in four economic partitions. High-value areas of provincial level were mainly distributed in the eastern coastal and border areas,and lowest-value areas were mainly distributed in the five provinces of Gansu,Shaanxi,Yunnan,Guizhou,and Sichuan,with the remaining areas at a middle-value level. Highest-value areas at the city and county levels were distributed along the "Xinjiang-Inner Mongolia-Heilongjiang" border in the north,along the Shandong Peninsula-Yangtze River Delta coast,and along Beijing-Guangzhou Line. 3) From the spatial correlation pattern,there was obvious spatial agglomeration phenomenon at town scale. Among them,the significant LL areas were widely distributed in the less developed regions of the provinces,and the significant HH areas were mainly distributed along the eastern coast,along the Yangtze river,and scattered in the north. 4) From the GWR model,the absolute value of the regression coefficient was ranked from large to small by the resident population in the built-up area> altitude > industrial output value> employees in the secondary and tertiary industries> proportion of employees in the secondary and tertiary industries> per capita industrial output value> population density> built-up area ratio,which indicated that only when the township economy developed to a certain stage and level can it have a good explanation relationship with industrial strength and the level of rural urbanization and industrialization.
