日本語
中国の再エネ上場企業186社・2012〜2023年のパネルデータを用い、政府補助金がグリーンイノベーションを促進することを二方向固定効果モデルで示した。資金制約は正の調整効果を持ち、制約が厳しい企業ほど補助金の限界効果が大きい。非国有企業、中小企業、中西部所在企業で効果が強い。
English
Using a 2012–2023 panel of 186 Chinese listed renewable energy firms, two-way fixed effects show government subsidies significantly promote green innovation. Financing constraints positively moderate this effect—subsidies matter more for cash-constrained firms, signaling creditors. Effects are stronger for non-SOEs, SMEs, and firms in central/western China.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX推進では脱炭素投資への公的支援（GX経済移行債、補助金）と資金制約の関係が政策的焦点であり、補助金設計の差別化や非上場・中小企業への支援配分を考える上で示唆がある。SSBJ開示とは直接の接点は薄いが、移行金融の実効性評価に参考となる。
In the global GX context
This adds empirical evidence to the global debate on how industrial policy and transition finance interact—showing subsidies work best where capital access is weakest. It informs subsidy design under frameworks like the EU Green Deal Industrial Plan and speaks to the effectiveness of public support for transition investment.

📄 Abstract（原文）
Renewable energy enterprises are central to the low-carbon transition, yet their green innovation is constrained by high technological uncertainty, long payback periods, and limited access to external finance. Government subsidies are among the most widely used policy instruments for correcting the resulting under-investment, but whether they actually stimulate green innovation, and under what financial conditions they work best, remains unclear. Drawing on market-failure theory, information-asymmetry theory, and signaling theory, this study examines the effect of government subsidies on green innovation in Chinese renewable energy listed companies and tests the moderating role of financing constraints. Using an unbalanced panel of 186 A-share listed renewable energy firms observed from 2012 to 2023 (1,794 firm-year observations), two-way fixed effects estimates show that government subsidies significantly promote green innovation, and the result is robust to alternative measures, instrumental-variable estimation, and Poisson pseudo-maximum likelihood estimation. Financing constraints positively moderate this relationship: the marginal effect of subsidies is larger for firms facing tighter constraints, consistent with the view that subsidies compensate for scarce external funds and send positive signals to creditors. The promoting effect is also stronger in non-state-owned enterprises, small and medium-sized enterprises, and firms located in central and western China. These findings enrich the literature on the financial conditions under which industrial policy is effective and offer practical implications for designing targeted and differentiated subsidy schemes that support the green transformation of the renewable energy sector.
