The contribution rate of the indigenous productive forces of paddy soil refers to the contribution of soil itself to rice production. It is an index widely used to reflect the basic soil fertility of rice field. In order to clarify the contribution rate of the indigenous productive forces of paddy soil of rice and its influencing factors，the literature published since 1970 was collected from China knowledge network，and the yield data of rice without fertilization treatment and nitrogen，phosphorus and potassium fertilizer treatments were sorted out to calculate the contribution rate of the indigenous productive forces of paddy soil. According to different periods，different regions，different soil fertility grades and different rice types，the data of contribution rate of the indigenous productive forces of paddy soil were classified，and the temporal and spatial characteristics and influencing factors of the contribution rate of the indigenous productive forces of paddy soil of rice in China were studied. The results showed that the average contribution rate of the indigenous productive forces of paddy soil of rice in China was 71.92%，and the largest number of samples with the data of contribution rate of the indigenous productive forces of paddy soil ranged from 70% to 80%，which was 33.61%. The contribution rate of the indigenous productive forces of paddy soil of rice showed an upward trend with time. There were obvious differences in the contribution rate of the indigenous productive forces of paddy soil in different planting areas，which was as follows:northeast rice area>southwest rice area>south China rice area>rice area in the middle and lower reaches of the Yangtze river；the contribution rate of the indigenous productive forces of paddy soil of rice increased with the increase of basic soil fertility level. There were significant differences in the contribution rate of the indigenous productive forces of paddy soil among different rice types，which were as follows:early rice>medium rice>late rice，hybrid rice>conventional rice，indica rice>japonica rice. To sum up，the rice is a crop with high dependence on indigenous productive forces of paddy soil，and the contribution rate of the indigenous productive forces of paddy soil is affected by time，region，soil fertility and rice type. Fertilizing the soil and improving the indigenous productive forces of paddy soil is an important way to achieve high and stable yield of rice.
