日本語

本研究は、グリーンクレジット(市場志向)とグリーン補助金(政府主導)の低炭素資源配分効果を統一フレームワークで比較。中国A株上場企業のデータを用いた実証分析により、両政策とも低炭素企業に優先配分されるが、グリーンクレジットの方がより強い選別効果を持つことを示した。政策改善への示唆を提供する。

English

This study compares the low-carbon resource allocation effects of green credit (market-oriented) and green subsidies (government-led) within a unified framework. Using data on China's A-share listed firms, it finds that both policies preferentially allocate resources to low-carbon firms, but green credit exhibits stronger screening. Provides implications for policy improvement.

📄 Abstract(原文)

Green credit is a market-oriented financial instrument. Green subsidies are government-led fiscal instruments. Both are important policy instruments for directing resources toward green sectors. However, existing studies have generally examined the two instruments separately, with few comparing their target recipients and low-carbon resource allocation characteristics within a unified framework. This study develops a theoretical model incorporating firms, banks, and the government and compares the allocation of capital and output to low-carbon firms relative to high-carbon firms under alternative policy scenarios. Building on this framework, this study conducts an empirical analysis using data on China’s A-share listed firms. The results show that corporate carbon emission intensity is significantly negatively associated with the probability of obtaining both green credit and green subsidies, indicating that both types of policy resources are generally allocated preferentially to low-carbon firms. Compared with green subsidies, green credit exhibits stronger screening of low-carbon firms. This study reveals differences between green credit and green subsidies in low-carbon resource allocation and provides guidance for improving both policy instruments.
