中国木材加工企业生产率与出口关系研究——基于经济政策不确定性视角

Research on the Relationship between Productivity and Export of Chinese Wood Processing Enterprises——Based on the Perspective of Economic Policy Uncertainty

选取中国工业企业数据库木材加工业微观层面的面板数据,基于OP法、ACF-OP法及LTFP的测算方法来计算木材加工企业的全要素生产率和劳动生产率,研究出口企业与内销企业生产率之间的关系以及中国木材加工业是否存在“生产率悖论”的现象。通过构建双向固定效应模型进而对中国木材加工企业全要素生产率与出口规模进行回归分析,并采用经济政策不确定性作为中国木材加工企业全要素生产率与出口规模之间的调节变量深入研究二者变量间的影响机制。研究结果表明:①1998—2013年中国木材加工企业中出口企业数量远小于内销企业,且1998—2011年木材加工企业不存在“生产率悖论”现象,中国木材加工企业的全要素生产率对企业出口规模具有促进作用;②在经济政策不确定性上升的情况下,中国木材加工企业全要素生产率对企业出口规模的正向影响更显著;③企业规模、企业盈利情况及企业资本密集度均为中国木材加工企业出口规模的正向影响因素。

By selecting the panel data at the micro level of wood processing industry in China's industrial enterprise database,this paper calculated the total factor productivity and labor productivity of wood processing enterprises based on the measurement methods of OP method,ACF-OP method and LTFP,and it studied the relationship between the productivity of export enterprises and domestic enterprises,and whether there was a“productivity paradox”in China's wood processing industry.By constructing a two-way fixed effect model,this paper made a regression analysis on the total factor productivity and export scale of Chinese wood processing enterprises,and used economic policy uncertainty as the regulating variable between the total factor productivity and export scale of Chinese wood processing enterprises to deeply study the influence mechanism between the two variables.The results showed that:①the number of export enterprises in China's wood processing enterprises from 1998 to 2013 was far less than that of domestic enterprises,and there is no“productivity paradox”in wood processing enterprises from 1998 to 2011.The total factor productivity of Chinese wood processing enterprises could promote the export of enterprises;②With the increase of economic policy uncertainty,the positive impact of total factor productivity on the export scale of Chinese wood processing enterprises was more significant;③Enterprise scale,enterprise profitability and enterprise capital intensity were all positive factors affecting the export scale of China's wood processing enterprises.
