China Finance and Economic Review 2018年第4期7卷 48-70页

作者： Wen Wang zao sun School of Economics and Finance of Xi’an Jiaotong University

Considering the important role the demand from manufacturing has played in the development of producer services,this paper analyzes the influence mechanism of manufacturing demand on producer services efficiency through two channels,which are the scale effect and innovation ***,the paper also evaluates the moderating effect of economic development level on the relationship between manufacturing demand and producer services *** on the panel data of China’s manufacturing industry and producer services from 1995 to 2014,the empirical result shows that:(1)the demand from manufacturing was helpful to improve producer services efficiency,and compared with the labor-intensive manufacturing,the demand from capital-intensive manufacturing played a more important role in improving producer services efficiency;(2)at different stages of economic development,the promoting effect of manufacturing demand on producer services efficiency showed a nonlinear threshold effect rather than a simple linear effect,namely after crossing a certain threshold of economic development level,the promoting effect would be more *** specifically the threshold level faced by capital-intensive manufacturing industry was higher than that faced by labor-intensive manufacturing *** findings may be helpful for governments to make industrial development strategy.

本土需求与企业自主创新——为何合理的收入分配更有利于企业创新

通过内需市场培育本土企业的自主创新能力迫在眉睫。文章认为收入不平等加剧导致的“创新产品需求不足”和消费结构中“进口高端产品挤出效应”会对本土创新产品市场需求产生明显抑制,最终将阻碍本土企业自主创新能力的提升。文章利用中国工业企业数据库及中国各省统计年鉴中规模以上工业企业相关数据,结合泰尔指数与广义熵指数等,在经验研究层面考察了开放条件下不同收入群体对于中国创新产品市场需求和本土企业自主创新能力的影响。结果表明:(1)高收入阶层相对较低的边际消费倾向不仅会通过一般商品的需求对本土企业的自主创新能力带来负面影响,同样也会通过创新产品的需求显著抑制本土企业自主创新能力的提升;(2)收入不平等还会通过进口产品消费偏好对本土企业自主创新能力产生负面影响;(3)扶贫和合理调节过高收入等政策都可以有效降低收入不平等对本土企业创新产品需求的负面影响,同时对过高收入的合理调节可以进一步控制进口产品带来的挤出效应,促进本土企业自主创新能力的提升。本文的研究有深刻的政策含义,新时期需要一个相对公平且更加有效的收入分配方案来正确引导本土市场需求,以有效承接本土企业的创新产品并促进企业自主创新,从而从需求侧为构建“国内大循环为主体、国内国际双循环相互促进的新发展格局”打造坚实基础。

去工业化促进了服务业效率提升吗

世界产业发展史表明,当一国进入工业化中后期,随着生产效率大幅提升,其产业结构演变亦呈现出明显的去工业化特征。以工业化国家为参照,现阶段我国人均收入远未达到工业化国家去工业化时的水平,此时收缩工业产出和就业规模,可视为一种被动去工业化,客观上不利于服务业效率的提升。本文利用2005—2014年我国制造业和服务业数据估计了去工业化对服务业效率的影响。在控制住市场结构和所有制结构等因素的影响后,研究结果显示:(1)去工业化与服务业效率之间呈现负相关关系;(2)去工业化通过提高劳动力成本对传统服务业效率产生负效应;(3)去工业化通过削弱制造业对服务业的有效需求从而不利于生产性服务业效率的提升。

文章利用浙江和陕西的经验数据估计了财政分权制度及地方政府优惠政策供给水平对转型期民营企业发展绩效差异的相关贡献。文章的主要发现是,由财政分权制度引发的地方政府激励差异对地区民营企业发展绩效差异的贡献并不像已有文献强调的那么显著;在地方政府的政策变化中,税收和融资政策贡献较为显著。文章的结论进一步揭示,与优惠政策本身相比,尽快从上到下形成一系列有效的政策执行体系,保证兑现政策政府与企业投资之间的交易承诺可能更具实质性意义。
