| Abstract: |
| Under the background of vigorous development of citrus industry in China, there is a double bottleneck, namely small scale of cultivated land and lack of labor resources. This study attempts to explore the sustainable and healthy development path of citrus industry from the perspective of total factor productivity. Based on the panel data of citrus production in China from 2011 to 2016, this study used the DEA Malmquist index method to measure total factor productivity of citrus , analyzed the dynamic evolution characteristics of citrus′ TFP, and compared the regional differences of total factor productivity of citrus，mandarin and tangerine. The results show that (1) From the overall trend, the total factor productivity of citrus in China has shown a downward trend since 2011, but the inter annual fluctuation is small. During the period of investigation, the average TFP growth rates of citrus, mandarin and orange are 2.6%, 2.0% and 2.3%, respectively. (2) From the impact of factors, technological progress is the main factors that affecting the growth of citrus′ TFP in China, pure technical efficiency and scale efficiency are important influencing factors of the total factor productivity. (3) From the regional differences, the technological progress plays an important role in improving the production efficiency of citrus industry in Fujian，Guangdong and other provinces, but the small scale of operation hinders the further improvement of production efficiency. And its growth advantage is obviously inferior to that of Jiangxi，Hunan province. (4) From the classification of citrus varieties, the technological improvement index and scale efficiency index of orange in most provinces are higher than that of mandarin, while the growth of total factor productivity of mandarin is relatively weak, which is only obvious in few provinces. It is an effective way to promote the total factor productivity growth of citrus in China by promoting the innovation of citrus science and technology, guiding moderate scale operation, cultivating new agricultural business entities and implementing citrus support policies according to local conditions. |
