【摘要】：根据广东农垦天然橡胶生产可获得数据和实际情况,分析了广东农垦天然橡胶的要素生产率,通过要素生产率得出广东农垦天然橡胶生产的技术进步类型。其次,采用随机前沿(SFA)方法测算了1992-2012年广东农垦及其三个主要植胶区(湛江局、茂名局、阳江局)天然橡胶生产技术效率。第三,运用Malmquist指数测算广东农垦及其三个主要植胶区天然橡胶生产全要素生产率及其分解指数。分析发现：第一,广东农垦割胶面积以及橡胶产量占全国比重逐年下降；第二,劳动力投入随着资金投入增加和土地投入减少而不断减少；第三,广东农垦天然橡胶生产技术进步类型属于资本节约型、劳动密集型和土地密集型模式,要素生产率增长率的关系为：劳动生产率增长率大于土地生产率增长率,土地生产率增长率大于资本生产率增长率；第四,通过随机前沿分析,1992-2012年广东农垦及其三个主要植胶区天然橡胶生产技术效率逐年下降,且湛江局技术效率大于农垦总局技术效率,农垦总局技术效率大于茂名局技术效率,茂名局技术效率大于阳江局技术效率；第五,与国内其他天然橡胶生产基地相比较,广东农垦天然橡胶技术效率较高；第六,通过Malmquist指数分解全要素生产率发现影响广东农垦技术效率下降的主要原因是规模效率无效。提高广东农垦天然橡胶生产效率的改进建议：一是促进技术进步,建立完善的橡胶技术培训和服务体系,提供一套现在农业生产要素,优化生产要素技术结合形式;二是合理规划投入资源,对规模收益递增的地区增加投入,规模收益递减的地区减少投入；三是提升天然橡胶产业聚集程度,改善区域内天然橡胶产业发展环境,提升橡胶产业在生产单位的比重。
[Abstract]:Based on the available data and actual situation of natural rubber production in Guangdong, the factor productivity of natural rubber in Guangdong was analyzed. Through factor productivity, we can get the types of technological progress of natural rubber production in Guangdong. Secondly. The technical efficiency of natural rubber production in Guangdong and its three main rubber planting areas (Zhanjiang Bureau, Maoming Bureau, Yangjiang Bureau) from 1992 to 2012 was calculated by means of random frontier SFA.3. The total factor productivity and decomposition index of natural rubber production in Guangdong agricultural reclamation and its three main rubber planting areas were measured by Malmquist index. The results showed that: first, the area of tapping rubber and the proportion of rubber production to the whole country decreased year by year in Guangdong province; Second, the input of labor force is decreasing with the increase of capital input and the decrease of land investment. Thirdly, the development of natural rubber production in Guangdong belongs to capital-saving, labor-intensive and land-intensive mode. The relationship between the growth rate of factor productivity is as follows: the growth rate of labor productivity is greater than that of land productivity, and the rate of land productivity growth is greater than that of capital productivity; In 4th, through random frontier analysis, the technical efficiency of natural rubber production in Guangdong and its three main rubber planting areas decreased year by year from 1992 to 2012, and the technical efficiency of Zhanjiang Bureau was higher than that of General Administration of Agriculture and Reclamation. The technical efficiency of the Bureau of Agriculture and Reclamation is greater than that of Maoming Bureau, and the Technical efficiency of Maoming Bureau is higher than that of Yangjiang Bureau. 5th, compared with other natural rubber production bases in China, Guangdong has a higher technical efficiency of natural rubber cultivation. In 6th, through the Malmquist index decomposition of total factor productivity, it was found that the main reason for the decline of Guangdong's agricultural reclamation technical efficiency was the inefficiency of scale efficiency. Suggestions for improving the production efficiency of natural rubber in Guangdong province are as follows: first, to promote technological progress, to establish a perfect rubber technical training and service system, and to provide a set of agricultural production factors. Optimizing the form of technological combination of factors of production; Second, rational planning of input resources, increasing investment in areas with increasing scale returns, and decreasing investment in areas with declining returns; The third is to improve the agglomeration of the natural rubber industry, improve the development environment of the natural rubber industry in the region, and enhance the proportion of the rubber industry in the production units.
