日本語

本論文は、制度・政策、インフラ・技術、金融・投資、社会・環境、人材・研究開発の五本柱フレームワークを構築し、ベトナムと中国の再生可能エネルギー法制度を比較分析する。中国は法体系の統合度・系統計画・資金調達手段・技術力で優位だが補助金未払いや地域的系統不均衡を抱え、ベトナムは電力法・直接PPA制度を整備したものの法規の分散や系統混雑、契約リスク配分の弱さが課題と示す。中国は移転可能なモデルではなく文脈適合的なベンチマークであり、ベトナム向けに規制継続性や銀行可能な契約等の段階的改革を提案する。

English

This article builds a Five-Pillar Framework (institutions, infrastructure, finance, society/environment, human resources) to compare renewable energy governance in Vietnam and China. China shows a more consolidated statutory framework, coordinated grid planning, and stronger technological capacity but faces subsidy arrears and regional grid imbalances; Vietnam has modernized electricity law and direct PPA rules yet suffers from legislative dispersion, grid congestion, and weak contractual risk allocation. China serves as a context-sensitive benchmark, and sequenced reforms are proposed for Vietnam.

📄 Abstract(原文)

Renewable energy transitions depend not only on capacity targets and financial incentives but also on coherent legal arrangements governing institutions, infrastructure, investment, environmental protection, and technological capability. This article develops a Five-Pillar Framework comprising Institutions and Policies, Infrastructure and Technology, Finance and Investment, Society and Environment, and Human Resources and Research and Development. It applies a comparative doctrinal and policy analysis to Vietnam and China, two state-led Asian economies with similar transition objectives but different regulatory maturity and implementation capacity. The assessment uses three cross-cutting criteria—legal certainty, institutional coherence, and implementation capacity—and is supplemented by a 2026 survey of 150 Vietnamese stakeholders from four professional groups. The findings show that China has a comparatively more consolidated statutory framework, coordinated grid planning, diversified financing instruments, and stronger domestic technological capacity, while also facing subsidy arrears, regional grid imbalances, and socio-environmental risks. Vietnam has modernized its electricity legislation, direct power purchase framework, and renewable-energy regulation, but implementation remains constrained by legislative dispersion, grid congestion, weak contractual risk allocation, and remaining limitations in the specificity and implementation of storage, social-impact, and innovation rules. China therefore offers a context-sensitive benchmark rather than a directly transferable model. The article proposes sequenced reforms for Vietnam, prioritizing regulatory continuity, bankable contracts, grid flexibility, social safeguards, legal coordination, and domestic innovation.
