High-speed rail reshapes how cities borrow money, study finds
New research reveals that high-speed rail projects materially alter municipal financing strategies and debt structures. The finding matters for city planners and investors evaluating infrastructure investments, as rail corridors appear to reshape local government access to capital markets and long-term fiscal planning.
Originaltitel: The impact of high-speed rail on city government debt financing
<p>While high-speed rail (HSR) investments in China are largely funded by the central government, their localized benefits often accrue to city governments. To examine how this mismatch shapes city financing behavior, we implement a difference-in-differences (DID) analysis using a comprehensive city–year panel dataset that includes HSR infrastructure, 3.69 billion individual HSR ticket sales records, and detailed information on Chengtou bonds (CTBs) issuance and outstanding balances. We find that HSR operation significantly increases CTBs issuance, with stronger effects associated with HSR passenger flows than with HSR mileage; in cities with higher land prices, greater population density, and higher fiscal openness; and for trunk HSR lines as well as bonds issued by HSR-related entities. However, this effect raises city governments’ debt-to-GDP and debt service ratios, particularly in less developed western regions, heightening local debt risks. These findings highlight the need for coordinated transport and fiscal policies to ensure sustainable infrastructure investments.</p>
