基于浙江工业企业微观数据的国有资本带动产业升级累计效应分析

Cumulative Effects Analysis of State-Owned Capital Driven Industry Promotion——Using Micro Data of Industrial Enterprises in Zhejiang

使用面板门限模型,通过国有资本比重对绩效影响系数在门限值前后的变化,分析国资带动产业升级作用的累计效果。通过设置虚拟变量区分不同行业类别,考察国资在哪些类别行业中能够起到对于整体的带动(挤进)作用或者挤出作用。实证结果显示,国资比例提高到门限值对于浙江整体企业管理水平有显著正向作用。国资在精细化工和医药等产业中的比例提升对于浙江整体经济的绩效有相比其他行业更加显著的正向作用,而这些行业不是明显的垄断行业。由此得出结论:国资在重点行业中的示范带动作用应该强化,以期累计作用结合混合所有制推进从而达到挤进民资和促进民企产业升级。

This article uses the panel threshold model to analyze the leading effect of the state- owned fund via analyzing the proportion on the state-owned funds and the private-owned funds to the change of performance elasticity coefficient. By segmenting different industries and setting up dummy variables, it is reasonable to find out the leading effects （squeezed in or squeezed out） of state-owned funds in different industries, and to analyze the causes and mechanism. The empirical results show that if the proportion of the state-owned funding meets the threshold, there is a positive relationship between the state-owned funds and the management level of private-owned funds in Zhejiang. The effect performs more significantly in the industry of metals and fine chemical and pharmaceutical man- ufacturing industry, and these industries are not obvious monopoly. Conclusion： The demonstration role of SOE in key industries should be strengthened ; advancing cumulative effects combined with mixed ownership will make the ＂squeeze into effect＂ with the qualitative changes of Chinese private enterprises and the promotion of industrial upgrading.
