Abstract: Taking the panel data of 31 provinces in mainland China from 2012 to 2022 as an example, a related model was used to analyze the development level of rural digital economy and new quality productivity and its regional differences in China. The results showed that the development level of rural digital economy and new quality productivity in each province had been improved to varying degrees from 2012 to 2022, but the rural digital economy being weak and the new quality productivity being weak, and the rural digital economy being strong and the new quality productivity being strong were the main distribution types; during the period of 2012-2022, the overall coupling and coordination degree of rural digital economy and new quality productivity in China’s provinces presented a more obvious gradient distribution characteristic, and the coupling and coordination level changed from mainly imbalance to mainly coordination; the gap of coupling and coordination degree of rural digital economy and new quality productivity in the four regions (east, central, west, and northeast) of China was relatively obvious, so it was necessary to strengthen the construction of digital infrastructure and talent incubation, promote the synergistic development of digital industry, and make up for the shortcomings of rural digital economy.
