中国装备制造业服务化水平测度——基于价值流动视角

依据GERT模型，从价值流动视角揭示国民经济系统整体视域下中国装备制造业与其它产业间价值增值量的变化规律及价值流动网络结构。依据产业间价值流动的价值增值乘数和价值平均转移次数等参数，构建中国装备制造业投入服务化和产出服务化水平指标并加以测度。结果表明，2002—2018年间，中国装备制造业投入服务化水平整体高于产出服务化水平，装备制造业投入服务化水平整体上呈轻微上升趋势，装备制造业产出服务化水平自2012年以后呈现上升发展趋势。

Measurement of the Service Level of China's Equipment Manufacturing Industry:based on the Perspective of Value Flow

Based on GERT model, this paper reveals the change law of value added and the structure of value flow network between China's equipment manufacturing industry and other industries from the perspective of value flow.Based on the parameters of value-added multiplier and average value transfer times of inter industry value flow, this paper constructs and measures the input service level and output service level of China's equipment manufacturing industry.The results show that: from 2002 to 2018, the level of "input service of equipment manufacturing industry" in China is higher than that of "output service of equipment manufacturing industry" on the whole, the level of "input service of equipment manufacturing industry" has a slight upward trend on the whole, and the level of "output service of equipment manufacturing industry" has an upward trend since 2012.
