我国主要荔枝品种生产规模与生产效率分析——基于2011—2013年的数据

Analysis of production scale and efficiency of main varieties of litchi in China——Based on 2011-2013 annual data

根据国家荔枝龙眼产业技术体系收集的2011—2013年度产业数据,首先从覆盖县区数量变动情况、生产面积变动情况和产量变动情况等3个维度分析了我国主要荔枝品种的生产规模发展状况,之后从单产和产值两个维度详细探究了我国主要荔枝品种的生产效率,计算出荔枝产业综合平均每667 m2产量和产值。结果表明,我国主要荔枝品种单产和产值偏低,且年度波动幅度较大;不同品种荔枝单产和产值年度变动走势不同,且品种间差异较大。

Based on the 2011--2013 annual industry data collected by National Litchi ＆ Longan Industry Technology System, this paper, firstly, analyzes the production scale development about Chinese main varieties of Litchi from the three dimensions of changes in the number of covered counties, production area and yield ; Secondly, this paper explores in detail the production efficiency of the main varieties of litchi from two dimensions of 667 m2 yield and its value, and calculates the comprehensive average yield and integrated average output of litchi industry.The results showed that the yield and output value of the main varieties of litchi is low, and the annual fluctuates are great; while the yield and output value of the main varieties of litchi show different annual changing trend, and there are significant difference among varieties.
