【Abstract】Over the past decades, the global financial system has become more integrated than ever, and finance has gradually replaced trade as one of the most important channels of risk contagion across countries. A clear understanding of the impact of global capital flow on its recipient countries thus has great significance to both policymakers and market regulators. Despite this, there remains a lack of rigorous empirical studies of how global capital flow impacts recipient countries, especially emerging markets. The literature uses time-series analysis (VAR) of aggregated variables to study the influences of short-term global capital flow (SGCF) on recipient countries. However, VAR analysis may not provide much insight into the channel of how SGCF affects these countries, as it not only overlooks the cross-sectional differences but also suffers from the identification problem. We use a panel data approach to investigate the impact of SGCF on Chinese firms’ cost of debt. A panel regression not only takes care of the cross-sectional difference of firms, but also controls for fixed effects. This advantage allows us to identify the heterogeneous impact of SGCF across firms. The uniqueness of the Chinese market makes it particularly suitable for such panel data analysis. China is one of the few countries in the world to adopt a managed floating exchange rate system and impose strict control on cross-border capital flows. This causes a significant amount of SGCF to sneak into China’s bank deposits through faked international trade by artificially inflating export prices and deflating import prices, which implies that custom cities with higher volumes of foreign trade are easier destinations of SGCF. In addition, the markets of bank loans are regionally segmented across different cities, and SGCF is expected to have a heterogeneous influence on the cost of debt of firms in different cities. Therefore, we hypothesize that the cost of debt of firms in these cities should be more sensitive to SGCF than those with lower volumes of foreign trade; this SGCF impact on cost of debt is consistent with changes in local bank deposits. To test these hypotheses, we consider the single term of SGCF and its interaction with the city’s previous-period foreign trade volume. We find that SGCF has a significant and heterogeneous impact on firms’ cost of debt. Consistent with our hypotheses, firms headquartered in cities with higher volumes of foreign trade are affected more by SGCF. In comparison, the general influences of SGCF based on aggregated VAR analysis are insignificant. The relation between cost of debt and SGCF may be reversed; that is, local credit conditions may shift the direction and increase the magnitude of SGCF. We deal with this issue by using the lag-period inflation rate of the United States as the instrument variable (IV) of SGCF. The empirical result of the IV analysis reveals that the endogeneity issue is not a concern for the crucial relation between SGCF and foreign trade volume. To further explore the channels of how SGCF affects the cost of debt of firms in different cities, and to verify our hypothesis that SGCF has a heterogeneous influence on the bank deposits of various cities, we run a regression analysis of bank deposits with SGCF and its interaction with local trade volume serving as the explanation variables. Our results show that those cities with larger trade volumes indeed see more bank deposit increases through capital flow. Furthermore, we study whether the impact of SGCF on the cost of debt can vary across industries. We find that the cost of debt of the manufacturing industry is more sensitive to SGCF than that of other industries. Further analyses show that this is because firms in the manufacturing industry rely more on bank loans as their funding resources than firms in other industries. Finally, we divide the sample into subsamples based on three periods and try other control variables to ensure the robustness of our results. We also carefully compare the empirical findings of this paper with the theoretical studies of SGCF and the sterilization operations of the People’s Bank of China.

    [2]. ① There are direct and indirect methods for the estimation of short-term global capital flows in the academic community. The direct method was first proposed by Cuddington (1986) and obtained the scale of short-term global capital flows by directly adding several items in a country’s balance of payments. However, Su and Tong (2011) pointed out that on the one hand, the coverage of direct method is too small, and the definition of hot money is somewhat arbitrary; on the other hand, the direct method ignores the hot money that may be hidden in the current account. The indirect method can avoid the above problems, so scholars use the indirect method to estimate short-term global capital flows, which was first proposed by the World Bank (1985).

    [3]. ① It is worth mentioning that the dollar inflation rate as a time series may also be related to the unobservable factors affecting the financing cost of enterprises, so that the instrumental variable of the dollar inflation rate is not exogenous. But we believe that, first, the dollar inflation rate reflects the development of the US domestic economy, which mainly affects the cost of capital for hot money. Therefore, the impact on the financing cost of Chinese enterprises is mainly reflected in the short-term global hot money flow. Second, in all regression analysis of this paper, we have controlled the main time series variables such as China’s loan interest rate, local financial development level index, local economic development GDP, and local inflation rate CPI, which may affect the financing costs of local enterprises. Therefore, in addition to the international hot money we want to consider, the dollar inflation rate should not be related to other unobservable factors that may affect corporate financing cost.
