第一产业内部产值结构变化及主要驱动因子研究——以成都市为例

第一产业是基础产业,其内部也存在各行业的经济竞争。引入了信息熵的概念,更好地反映了第一产业内部产值结构的变化。经过对熵值的小波变换,提取了各熵值变化的突变点。在对突变点分析之后得出,国家政策和特大自然灾害是影响第一产业内部产值结构的因素,并针对现在第一产业内部产值结构的现状提出了对策。

Changes of Internal Production Value Constitution of Primary Industry and Driving Force Analysis

Primary industry is the fundamental industry,and has economic competitions in its internal composition.Shannon entropy was introduced to reflect the changes of internal product constitution of primary industry more clearly.Based on wavelet analysis of Shannon entropy number,mutations of the Shannon entropy number change were found out.After analyzing these mutations,it was concluded that the policy and especially serious disaster were factors influencing the changes of internal product constitution of primary industry.Strategies were put forward according to the status of internal product constitution of primary industry.
