摘要
过程创新和产品创新作为技术进步的具体形式,通过产品与服务生产效率的提高和产品种类的增加影响着经济体中的生产要素分配、劳动者收入和就业以及最终消费。通过构建产品与服务生产的两部门模型,分析过程创新和产品创新对服务消费影响的具体路径,并根据中国省际1995—2017年的面板数据进行实证检验。研究发现,技术进步通过中介变量劳动力就业影响居民服务消费水平,其中就业人数在过程创新和服务消费关系中起到部分中介效应,就业人数在产品创新和服务消费小样本关系中起到完全中介效应;进一步的,当前我国过程创新降低了服务消费的收入弹性,产品创新则提高了服务消费的收入弹性。
As the specific forms of technological progress,process innovation and product innovation affect the distribution of production factors,labor income,employment and final consumption through the improvement of product and service production efficiency and the increase of product categories.This paper constructs a two-sector model of product and service production,analyzes the specific path of the impact of process innovation and product innovation on service consumption,and conducts an empirical test based on China’s provincial panel data from 1995 to 2017.The study found that technological progress affects the level of residents’service consumption through the intermediary variable labor employment.The number of employees plays a partial mediating effect in the relationship between process innovation and service consumption and a complete mediating effect in the relationship between product innovation and service consumption in a small sample.Further,China’s current process innovation reduces the income elasticity of service consumption,while product innovation improves the income elasticity of service consumption.
