Abstract:Based on the research of influencing factors on agricultural economy, an evaluation system of agricultural infrastructure in northwest inland was built with effective irrigation area, rural highway mileage, total power of agricultural machinery and rural electricity consumption as four important indicators. Then the indicator weight in this evaluation system was calculated by C-D model and panel data, and finally, the development of overall agricultural infrastructure was discussed. The results showed that in northwest inland, Xinjiang led the integrated development level of agricultural infrastructure, followed by Shanxi, Ningxia, Qinghai, Gansu. The development of agricultural infrastructure in the northwest inland was backward and unbalanced. The key issues facing the northwest region were still the solution to the basic needs of living conditions, the gradual growth of the agricultural economy and the low quality construction of agricultural infrastructure. Therefore, in the construction of agricultural infrastructure in the northwest region, it is necessary to use the spillover effect of the Belt and Road and the development strategy of the western region to strengthen the investment in agricultural infrastructure, supplement the advantages of short-board strengthening and enhance self-creation. At the same time, it is necessary to formulate precise policies for the problems existed in the provinces, so as to promote the healthy and stable development of the agricultural economy in the inland areas of the northwest.
