种养结合整体绿色技术效率的测度与分析
MEASUREMENT AND ANALYSIS OF THE OVERALL GREEN TECHNOLOGY EFFICIENCY OF THE COMBINATION OF PLANTING AND BREEDING
摘要
Abstract
A thorough assessment of the benefits and challenges of the integration of planting and breeding is crucial for advancing sustainable agriculture development.Based on micro panel data on the cost-benefit of agricultural products for farmers in Jiangsu province from 2009 to 2017,this paper selected farmers who combine planting and breeding under the"pig farming+grain planting"model as the research object,adopted the network SBM-DEA model to measure and analyze the overall green technology efficiency of the combination of planting and breeding,and employed the Tobit model to analyze the influencing factors of the overall green technology efficiency of the combination of planting and breeding.The results showed that:(1)The average of overall green technology efficiency of the combination of planting and breeding was 0.8960,and the annual growth rate was 1.499％.(2)The overall green technology efficiency of the combination of breeding and breeding was higher than that of the green technology efficiency of pig breeding and the green technology efficiency of grain production,and the correlation with the green technology efficiency of pig breeding was stronger.(3)The combination of planting and breeding farmer's age,education level,pig farming technology level,and grain planting technology level had a positive impact on the overall green technology efficiency of the combination of planting and breeding;The proportion of pig breeding employees and the number of types of grain crops planted had a negative impact on the overall green technology efficiency of the combination of planting and breeding.(4)There was an inverted U-shaped relationship between the ratio of pig breeding quantity to grain planting area and the overall green technology efficiency of the combination of planting and breeding.When and only when the ratio of pig breeding quantity to grain planting area was equal to 3.89 heads/mu·year,the overall green technology efficiency of the combination of breeding and breeding reached the highest.Therefore,to promote the development of circular agriculture combining planting and breeding,it is proposed to use the overall green technology efficiency of planting and breeding as an evaluation indicator,reasonably allocate the number of pig farms and grain planting area,and regularly conduct agricultural technology training for farmers who combine planting and breeding,etc.关键词
