摘要：

采用DEA-mamlquist指数测算2004—2019年中国17个玉米主产省(区)的全要素生产率,运用联立方程组模型实证检验农村互联网发展对玉米全要素生产率的影响及其作用机理,并分区域探讨其差异性。结果显示:2004—2019年中国玉米全要素生产率年均增长0.2%,主要依靠技术进步的单轨模式驱动。农村互联网的发展显著(P<0.01)提升玉米全要素生产率,主要依靠技术进步和技术效率的协同作用驱动。分区域来看,农村互联网发展对玉米全要素生产率均具有显著(P<0.01)的促进作用,其影响程度由高到低依次为北方春播玉米区>黄淮海平原夏播玉米区>西北灌溉玉米区>西南山地玉米区。建议进一步提高农村互联网的配套设施建设,发挥互联网“连接经济”的优势,应用多元化互联网技术,促进不同生态类型区玉米生产效率的提升。

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
