潜在比较优势与重点产业政策效果——基于企业僵尸化的视角

重点产业政策是引导企业实现特定经济社会目标、明晰潜在转型路径和推动结构调整的重要手段。文章基于2001—2015年中国海关数据,从行业相似度视角测度了潜在比较优势,然后采用中国工业企业数据,考察了重点产业政策偏离潜在比较优势对企业僵尸化的影响及作用机制。研究发现,当重点产业政策偏离潜在比较优势而产生政策扭曲时,会形成"僵尸企业"诱发效应。考虑央地关系的结果表明,中央和地方同时支持形成的重点产业政策扭曲对企业僵尸化的正向影响最大,而仅地方支持的影响最小。异质性分析显示,重点产业政策偏离潜在比较优势的"僵尸企业"诱发效应在国有企业、劳动密集型企业、融资约束较大的企业中更加显著。机制检验表明,重点产业政策与潜在比较优势的偏离从投资不足和过度投资两个方面加剧了企业非效率投资,并通过挤出正常企业和挤入"僵尸企业",阻碍正常企业进入和"僵尸企业"复活等方式扭曲了企业进入退出机制,最终加深了企业僵尸化程度。文章拓展了重点产业政策经济效应评估的视角,丰富了"僵尸企业"影响因素的研究,为减少产业盲从行为并唤醒因势利导的产业发展意识提供了有益的政策启示。
Potential Comparative Advantages and the Effect of Key Industrial Policies: From the Perspective of Firm Zombification
Key industrial policies are important measures for the government to intervene in the eco-nomy with tangible hands, but in the actual process of policy implementation, key industrial policies may devi-ate from potential comparative advantages of the region. At the same time, China's economic development is still faced with the problem of zombie firms, and the COVID-19 epidemic has also provided conditions for the survival of zombie firms. Therefore, it is worth paying attention to whether there is a certain correlation between the implementation of industrial policies and the formation of zombie firms, and revealing the rela-tionship between the two has practical significance.Based on the data of China's industrial firms and customs, this paper examines the impact and mechan-ism of the deviation of key industrial policies from potential comparative advantages on firm zombification. The study finds that this deviation will lead to the induced effect of zombie firms. Considering the central-loc-al relationship, the results show that the distortion of key industrial policies formed by both central and local support has the largest impact on zombie firms, while the impact of only local support is the smallest. Hetero-geneity analysis shows that the induced effect of zombie firms with key industrial policies deviating from po-tential comparative advantages mainly exists in state-owned firms, labor-intensive firms, and firms with large financing constraints. Mechanism testing shows that the deviation of key industrial policies from potential comparative advantages promotes inefficient investment and distorts the entry and exit channel, ultimately deepening the degree of firm zombification.The marginal contributions of this paper are as follows: First, based on the unique perspective of the devi-ation of key industrial policies from potential comparative advantages, it explores for the first time the in-duced effect of key industrial policies on zombie firms, which effectively supplements the relevant literature on the influencing factors of zombie firms. Second, the systematic investigation on the zombie effect of key in-dustrial policies deviating from potential comparative advantages not only expands the scope of industrial policy research, but also expands the relevant literature on the evaluation of the economic effect of industrial policies. Third, it extends the strategic trade theory and the product space theory from the perspective of do-mestic division of labor, and responds to the debate in relevant research on whether key industrial policies should follow comparative advantages. This paper also provides important insights for the government to choose key supporting industries, improve industrial policy implementation plans, and effectively dispose of zombie firms.
