Abstract
While the aging of agricultural labor force and its impact on agricultural production have been attracting extensive attention, little is known about the relationship between aging of agricultural labor force and technical efficiency in the garlic production. Based on the survey data of garlic growers in Lanling County, Shandong Province, the Data envelopment analysis (DEA) model is used to measure the production technical efficiency of garlic growers in 84 villages in Lanling County, Shandong Province, with the aging of the labor force. The distribution characteristics and changing trends of garlic production technology efficiency are analyzed in terms of family characteristics and garlic planting characteristics, and regression analysis is performed on the differences of the results. The study found the following: (1) Garlic growers in Lanling County, Shandong Province, accounted for a high proportion of laborers over 60 years old, and their physical health status was weaker than that of young laborers, which reduced the technical efficiency of garlic planting and production. (2) The number of garlic varieties grown by garlic growers and the number of garlic planted in acres have a significant negative impact on the technical efficiency of garlic planting by farmers. (3) There is a significant positive correlation between the annual household income of farmers and the production technology efficiency of garlic growers; when the number of garlic training is not more than three times, it has a positive impact on the production technology efficiency of garlic planting by farmers, and more than three times are related to garlic production technology. The efficiency is negatively correlated.
Highlights
This paper firstly calculates the comprehensive technical efficiency (TE), the pure technical efficiency (PTE), and the scale efficiency (SE) of farmers in the first stage, and uses the above three types of efficiency values of farmers to influence the efficiency of each environment
The variables are subjected to Tobit model regression analysis in the second stage, and the inflection points of the above three types of efficiency values of farmers are analyzed in detail
Based on the survey data of farmers in Lanling County, Shandong Province, this paper uses the Data envelopment analysis (DEA)–Tobit model to study the impact of the aging of the rural labor force on the technical efficiency scores of garlic growers and other environmental variables on the production technical efficiency of the planting industry
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Since the 1980s, with the rapid economic development, the proportion of China’s aging population has been increasing [1], and the proportion of the population engaged in primary industry has declined [2], which leads to the aggravation of the aging degree of the labor force [3]. The aging of the agricultural labor force is an important part of the labor aging process. This problem is widespread in countries and regions such as China, the United States, Japan, Europe, Southeast Asia, and Oceania.
