基于关联度和梯度的浙江省产业间影响力分析

Analysis on Inter-industrial Influence in Zhejiang Province Based on Industrial Correlation Degree and Industrial Gradient

利用2002年、2005年和2007年浙江省的投入产出表,测度上述3个年份浙江省的产业关联度和梯度,并进行产业分类。结果显示:利用产业梯度测度方法可直接抓住对地区经济发展最有影响力的产业,其测度效果优于产业关联度测度方法,但产业关联度测度在产业分类上具有优势。根据关联度进行排序,同时进行梯度测度,对照验证发现:浙江省的化学工业,通用、专用设备制造业,纺织业,建筑业是对其经济发展贡献最大的支柱产业;金属冶炼及压延加工业、金属制品业、电子通信设备及计算机制造业等是对其经济增长贡献快速增长的产业;批发和零售贸易业,农业,电力、热力的生产和供应业的贡献虽然有所减小,但其稳定经济的作用不可忽视。

Based on I/O Tables in Zhejiang province in 2002,2005 and 2007, this paper measures the industrial influence correlation degrees and the industrial gradients of Zhejiang province in three years,and classifies the industries in Zhejiang province. The result shows as follows：measuring industrial gradient helps to grasp the industry influencing regional economy most significantly,and its effect is better than that of industrial correlation degree,but the latter has the classification advantage; chemical industry, general purpose equipment industry, textiles industry and construction industry make the greatest contributions to Zhejiangs economic development;metal smelting industry,fabricated metal product industry, electronic communications equipment and computer manufacturing industry are improving rapidly; wholesale and retail trade industry, agricultural industry, electricity, heat production and supplement industry contribute to it at a weaken level, but their stabilities could not be ignored.
