2008-2013年中国渔民收入结构变化及拉动力分析

依据国家最新渔民收入统计制度，研究中国渔民收入结构在2008-2013年的变化趋势。利用灰色关联度量化综合模型，从变化率差异和绝对值差异两个角度，对渔民收入结构与渔民总收入的关联度进行分析，发现家庭经营收入与渔民总收入的关联度名列第一；基于强调变化率差异，财产性收入关联度名列第二；基于强调绝对差异分析，工资性收入关联度排第二位。通过进一步分析渔民收入结构对渔民总收入的贡献率和拉动力，分析发现，家庭其他经营收入对家庭经营收入提供的贡献率和拉动力高于来自渔业生产收入所提供的贡献率和拉动力，这表明渔民劳动力已产生明显分化。生产性补贴成为影响渔民收入的第二大要素，其对渔民收入的贡献率与拉动力皆名列第二。渔民工资性收入的拉动力主要来源于其他行业，说明渔业雇工水平低、渔业产业工资水平低；渔民土地和水面经营权租金对渔民财产性收入的增长产生明显的负影响，作业渔场缩减等问题制约了渔民增收。

Analysis of the changes of fishermen's income structure and the traction from 2008 to 2013 in China

According to the latest fishermen income statistics system stipulated by China National Bureau of Statistics, this paper analyzes the changes about fishermen's income structure between 2008-2013 in China. Through comprehensive computation model of grey incidence degree, we analysed the correlation degree about fishermen's income structure and fishermen's income in view of the rate differences and the absolute differences. We found the fishermen's family management income has the highest relevancy degree with fishermen's income. Based on the rate differences, the relevancy degree of fisehermen's property income is at the second place. Based on the absolute differences, the relevancy degree of fisheermen's wage income is at the second place. Through the analysis of the contribution rate and the traction from every part of Chinese fishermen's total income. We found that the contribution rate and traction offered by other household income to household business operation income are higher than that offered by fishery production income. It shows that the labour force of fishermen has obviously differentiated. The productive subsidy becomes the second element which affects fishermen income. The productive subsidy has the second relevancy degree with fishermen's income, the contribution rate and traction to fishermen's income. The traction of fishermen's wage income mainly came from the other industries, it means the low level of fishery employment and the low level of fishery industry wage. Fisheremen's rent of land-use right has the obvious negative impact to the increase of fishermen's property income, the cutting of fishing grounds restricts fishermen to increase their income.
