城市规模与分产业制造业企业全要素生产率的关系研究

On the relationship between urban scale and total factor productivity of manufacturing enterprises

通过在城市规模与企业全要素生产率关系研究中控制产业变量,使用2000—2013年企业数据和城市层面数据结合建立面板门槛模型。结果发现:在不控制产业变量时,当人口规模在283万~812万时,城市规模对企业全要素生产率影响系数最大;城市规模对劳动密集型企业在城市规模较小时系数最大,对资本密集型企业在城市规模较大时影响更大;按国民经济大类区分产业时,城市规模对产业企业全要素生产率的影响表现为3种不同的情况。由于城市规模对不同产业的企业全要素生产率影响不同,城市在产业政策上应选择能最大程度发挥城市规模优势的产业,而企业在选址决策中也应将城市规模因素纳入考虑范围。

Through the study on the city scale and enterprises＇ total factor productivity by controlling industry variables,using combining data of enterprises from 2000 to 2013 and city level data,this paper has set up panel threshold model and found： in the model without controlling industry variables,when the population size is in 2. 83 ~ 8. 12 million,city scale have the biggest influence coefficient on total factor productivity of enterprises; city scale of labor intensive industry enterprises in the coefficient of city scale is small,the largest impact on capital-intensive enterprises total factor productivity,a greater role in urban size is larger; According to the categories of the national economy to distinguish industries,city scale of industry enterprises performance of total factor productivity is characterized three different situations. Urban size for total factor productivity affect different enterprises of different industries,urban industrial policy should be aimed at the urban scale selection for maximum absorption of the city scale advantage industry,and urban scale factors should be taken into account while making decisions about enterprises＇ location.
