Can Trade Facilitation Prevent the Formation of Zombie Firms? Evidence from the China Railway Express

Using data on firms listed on Chinese A‐share markets from 2009 to 2017, this paper applies the difference‐in‐difference model to test the effect of trade facilitation on preventing the formation of zombie firms. We find that the China Railway Express (CRE) significantly prevented the formation of such firms. Mechanism tests show: (i) the CRE has accelerated the speed of sales, which increased the overseas sales revenue of firms; (ii) the economies of scale and the capital accumulation effect caused by the CRE can help increase firms’ solvency and development ability. Heterogeneity analysis indicates that the effect of the CRE on preventing the formation of zombie firms is mainly reflected in non‐state‐owned firms, firms in highly competitive industries, and firms in the eastern region of China. We suggest that China should continue to promote trade facilitation by expanding the CRE and strengthening the market's dominant role in preventing the formation of zombie firms. Disadvantaged firms should seize the development opportunities brought by the CRE.     

企业过度投资挤出了创新吗——基于“中国企业-劳动力匹配调查”（CEES）的实证分析

与现有文献多从制度环境、企业家能力角度研究企业创新能力制约因素有所不同，从企业投资行为选择这一独特视角，就企业过度投资对自身创新能力的挤出效应进行稳健性检验。基于“中国企业-劳动力匹配调查”（CEES）一手微观数据进行检验，结果发现：在相关因素充分控制的前提下，企业在研发创新领域以外的过度投资对于企业专利产出与产品创新均具有显著负向影响，表明企业投资行为扭曲对自身创新能力形成了较为突出的挤出效应。进一步分析发现，过度投资显著降低了企业技术研发投入，不利于企业人力资本结构优化与管理效率提升，这些因素是企业过度投资抑制创新能力提升的主要渠道。为此，建议通过营造公平竞争的营商环境，抑制企业过度投资行为。

The Market Shares of Small and Medium Scale Enterprises in Taiwan Manufacturing

Small and medium-sized enterprises (SMEs) have played an important role in many countries’ industrial development. Among these countries, Taiwan is well known for the outstanding performance of its SMEs. Limited knowledge about the causes of such performance has been revealed gradually. The main purpose of this study is to explore the determinants of SMEs’ market shares in Taiwan’s manufacturing sector. According to economics literature, economies of scale determine the market share of SMEs. The usual explanation given is that economies of scale create barriers against SMEs entering the market and competing efficiently with larger firms. It is also said that the strong entrepreneurial drive to have a self-owned business is a crucial explanation for the creation of new businesses, usually as offshoots from a small one. Finally, such factors such as an even-handed policy scheme, the availability of technology in relation to R&D, transaction costs, and so forth, are also important for creating a favourable environment for SMEs. Applying cross-industry pooling data from 1976 to 1986, the market shares of SMEs in Taiwan’s manufacturing sector were found to be affected by the following factors: (1) SMEs’ performance related to labour productivity and their willingness to set up new enterprises; (2) institutional factors including low entry barriers, suitable technology, the adoption of a subcontract system, and prosperous export markets. The empirical findings are compared with those from studies of the US and Germany.
