Differential Analysis of the Efficiency of Fixed Assets Investment in the Primary Industry in Ningxia Province

摘要

This paper selects data from 18 counties in Ningxia province from 2003 to 2017, and uses the incremental capital-output ratio to measure the efficiency of fixed asset investment in the primary industry. Then we analyze the differences between poor and non-poor counties from the time and cross-section. The results show that from 2003 to 2017, the efficiency of fixed asset investment in the primary industry in Ningxia was significantly different between poor and non-poor counties, and poor counties was lower than non-poor counties. Therefore, there is great potential for improving the efficiency of fixed asset investment in the primary industries of poor counties.
