成渝经济区生态农业对区域经济影响分析

目的]区域经济发展反映经济各个方面的综合发展状况,探讨其影响因素以确定区域未来经济的发展方向,为进一步规划发展提供科学依据。方法]先构建生态农业评价指标体系再采用层析分析法确定权重,结合线性加权和函数计算生态农业评价指数,通过相关分析法分析生态农业各个指标与区域经济的关系,最终确定生态农业对成渝经济区经济的影响程度。结果]生态农业指标中评价指数大于0.9是森林覆盖率,介于0.8~0.7的包括投入产出比、土地生产率、农业科技贡献率、万人拥有的科技人员、劳动生产率、化肥施用量。且生态农业中各个指标与GDP都正相关,其中森林覆盖率、人均收入增长率、农业科技贡献率和万人拥有的科技人员与GDP显著相关,对区域经济的影响最大。结论]成渝经济区经济受生态农业的影响,进一步选取更多生态农业相关因素,对于全面促进区域经济持续发展具有十分的重要现实意义。

ANALYSIS ON THE IMPACT OF ECOLOGICAL AGRICULTUREIN CHENGYU ECONOMIC ZONE

The development of the regional economy reflects the comprehensive development status of various aspects of the economy, this paper discussed its influencing factors to determine the future economic development direction of the region, and provides scientific basis for further planning and development.The evaluation index system of the ecological system was constructed, then the weights were determined by tomographic analysis, and the evaluation index of ecological agriculture was calculated by combining the linear weighted and function. The relationship between various indicators of ecological agriculture and regional economy was analyzed through correlation analysis, and finally determined the influence of ecological agriculture on economy of Chengdu-Chongqing Economic Zone.The results indicated that the evaluation index of the eco-agriculturehigher than 0.9 was the forest coverage rate, which ranges from 0.8 to 0.7 were the input-output ratio, the land productivity, the contribution rate of agricultural science and technology, the scientific and technical personnel owned by ten thousand people, and labor productivity, chemical fertilizer application amounts. In addition, various indicators of eco-agriculture were positively related to GDP. Among them, the forest coverage rate, per capita income growth rate, agricultural science and technology contribution rate, and the scientific and technical personnel were owned by ten thousand people significantly related to GDP. The economy of Chengdu-Chongqing Economic Zone was affected by ecological agriculture, and further selection of more relevant factors of ecological agriculture will have a very important and practical significance for comprehensively promoting the sustainable development of regional economy.
