新疆の4炭層メタンブロックを対象にシステムダイナミクスモデルを構築し、15年間の会計結果と坑井稼働を連動させた。炭層メタン価格・補助金・税制の各シナリオを検証し、価格10%上昇や法人税半減が累積損益を改善する一方、減退期の年間損失や投資遅延が残ることを示す。政策効果はブロックと開発段階ごとに評価すべきと結論づける。
English
A system dynamics model calibrated to four low-rank CBM blocks in Xinjiang links well commissioning to 15-year accounting outcomes. Scenarios on CBM price, output subsidies, and taxes show a 10% price rise or halved corporate income tax can turn cumulative results positive, yet annual losses persist in decline and investment lags blunt subsidy effects. Policy effects should thus be assessed by block and development stage.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では炭層メタン開発の直接的な政策接点は乏しいが、補助金・税制・投資回収期間を段階別に評価する枠組みは、日本のGX経済移行債やトランジション支援の政策設計議論に示唆を与える。
In the global GX context
Adds to transition-finance and energy-policy scholarship by quantifying how subsidy timing and tax incentives interact with long payback periods in early-stage fossil-gas projects, relevant to debates on transition finance eligibility and stranded-asset risk.

📄 Abstract（原文）
Against the backdrop of ongoing efforts to increase natural gas reserves and production and advance the low-carbon energy transition, the importance of developing low-rank coalbed methane is becoming increasingly evident. However, its early-stage development faces challenges such as phased production evolution, long investment payback periods, and uncertainty regarding the effectiveness of policy incentives. We calibrate a system dynamics model for four blocks in Xinjiang to link well commissioning and production with annual accounting outcomes over 15 years. Separate scenarios test changes in CBM price, incremental-output subsidies, and taxes; technological accumulation and carbon revenue are examined as extensions. Without reinvestment, Baicheng has the highest cumulative output but a CNY 138 million after-tax accounting loss. A 10% CBM price increase makes the accounting sum positive while annual losses persist late in decline. In the hypothetical case allocating all subsidy receipts to new wells, Baicheng adds 28 wells at the baseline subsidy rate under the one-year funding lag and whole-well investment rule, while retaining a cumulative accounting loss. In the tax scenarios with 3% profit reinvestment, halving corporate income tax raises Baicheng’s cumulative profit from CNY −143 million to CNY 14 million without changing its well count. These results distinguish immediate financial gains from subsequent investment responses and show why policy effects should be assessed by block and development stage.
