【摘要】：在构建的结构分解模型中将海洋渔业捕捞量变动分解为资源消耗强度变动效应、经济技术系数变动效应、最终需求水平变动效应、最终需求系数变动效应和最终需求分布变动效应等。根据山东省1997年和2007年的投入产出表提供的数据,运用构建的模型对该省近十年的海洋鱼类、软体动物和甲壳动物等三类海洋渔业资源捕捞量变动的因素分解效应进行了分析。结果表明:海洋渔业资源捕捞量下降与资源消耗强度变动效应、经济技术变动效应正相关,而与最终需求变动效应负相关;最终需求水平变动、最终需求系数变动和最终需求分布变动对三类渔业资源需求量变动均具有增量化作用,其中最终需求水平变动的增量化作用最明显;不论是减量化作用,还是增量化作用,鱼类资源需求的五类变动效应最为明显;经济技术变动效应的六部门分解效应中,工业部门的减量化作用最为明显,渔业和服务业部门的增量化作用最为明显。
[Abstract]:In the structural decomposition model, the variation of marine fishery catch is decomposed into resource consumption intensity change effect, economic and technical coefficient change effect, final demand level change effect. According to the data from the input-output tables of Shandong Province in 1997 and 2007, the model is used to analyze the marine fish in Shandong Province in the past ten years. The factor decomposition effects of three kinds of marine fishery resources, such as molluscs and crustaceans, were analyzed. The results showed that the decline of marine fishery resources was positively related to the change of resource consumption intensity, and the effect of economic and technological change. The change of final demand level, the change of final demand coefficient and the change of final demand distribution have incremental effect on the change of fishery resource demand. Among them, the increment effect of the final demand level change is the most obvious; whether it is the reduction effect or the incremental effect, the five kinds of change effect of fish resource demand is the most obvious; in the six sectors decomposition effect of the economic and technological change effect, The reduction effect of industrial sector is the most obvious, and the increment effect of fishery and service sector is the most obvious.
