摘要伴随经济的发展，广东农业处在全面发展时期，需要把握好农业发展的方向和模式。先了解广东城市经济状况所处地位与农业产业增加值是有相关性的，普遍是GDP越高的城市，它的产业增加值也较高；接着，用数据包络分析2006-2013年广东农业发展效率上存在的问题，就总体而言，农业效率是有提高的，并且处在比较平稳的水平，主要不足是规模效率偏低，这就要求有关部门在扩大产业规模时，要协调好每个经济变量的投入，降低产业浪费，以便增加产业的输出，提高规模收益；最后，我用主成分分析将原来的5个经济变量减少到2个主成分，为以后的研究提供方便，同时，在主成分基础上，我们建立综合评价模型，发现发展趋势是曲线上升的，农业可持续发展经历了2006至2009年的困难期和2010至2013年的发展期，困难期经济投入很低造成当时发展不理想，近几年仍是农业的发展期。有关部门应抓住时机，深入了解农业投入产出绩效的情况和发展趋势效仿发展时期农业的发展模式，制定有利的政策措施。45640

Abstract
Along with economic development, but also in the overall development of agriculture in Guangdong period, you need a good grasp of the direction and mode of agricultural development. Guangdong city to understand the economic situation of the status and value added of agricultural production are related, and are generally the higher the GDP of the city, its industry was also higher; then, with data envelopment analysis 2006-2013 Guangdong Agricultural present on the development efficiency, on the whole, agricultural efficiency is improved, and at a relatively stable level, the main drawback is the low efficiency of scale, which requires authorities at the time to expand the industrial scale, to coordinate inputs for each economic variable, to avoid industrial waste, in order to increase the output of the industry and improve returns to scale; and finally, I used principal component analysis to reduce the original five economic variables to the two main components to facilitate future research at the same time, the principal component basis, we have established a comprehensive evaluation model and found that the trend is upward curve, sustainable development of agriculture has experienced difficulties in 2006-2009 period and the 2010-2013 period of development, economic investment very difficult period low unsatisfactory result was the development in recent years, is still the development of agriculture. Authorities should seize the opportunity to understand the performance of the overall output of agricultural inputs and trends to follow the development of agriculture during the development of models and methods, the development of an enabling policy measures.
