Abstract

Abstract:

In the present study, the DEA-Mamlquist index was introduced to estimate the total factor productivity of 17 major maize producing provinces (autonomous regions) in China from 2004 to 2019,and the simultaneous equations model was uesd to test the impact and reveal the mechanism of Internet development in rural area on the total factor productivity of maize. It was shown that the average annual growth rate of maize total factor productivity in 2004-2019 was 0.2%, which was mainly attributed to the technical progress. The Internet development in rural area has significantly (P<0.01) increased the total factor productivity of maize, which was mainly attributed to both the technical progress and technical efficiency. In different ecological areas, the Internet development in rural area has significant (P<0.01) promotion effect on the total factor productivity of maize, and the influence decreased as spring maize planting area in north China>summer maize planting area in Huang-Huai-Hai Plain>northwest irrigated maize area>southwest mountainous maize area. Accordingly, it was suggested to improve the construction of the rural Internet supporting infrastructure, take the advantage of the “connectivity economy” of the Internet, and diversify Internet technologies to promote maize total factor productivity in different ecological areas.

Key words: Internet development in rural area, total factor productivity, maize, technological progress, technical efficiency
