Financial Risk Analysis of Green Certificate Market Based on Sustainable Development of Renewable Energy
This study employs a "goal-mechanism-risk-governance" framework and empirical analysis of Chinese data to identify critical financial risks in the green certificate market, revealing significant price volatility, liquidity paradoxes, and high entity concentration that collectively elevate the comprehensive financial risk index despite rising certificate prices.

Imagine the world's energy system as a giant, bustling kitchen where chefs (power plants) are trying to cook up clean meals using wind and sun instead of fossil fuels. But there's a problem: these clean meals are expensive to make, and sometimes the kitchen is chaotic. To fix this, governments invented a special "Green Certificate." Think of it like a digital sticker or a collectible trading card that proves you've used clean energy. Companies buy these stickers to show they are helping the planet, just like collecting rare cards proves you're a serious gamer. However, just like any trading card market, these stickers can be tricky. Sometimes their value goes up and down wildly, sometimes it's hard to find someone to trade with, and sometimes the rules of the game change overnight. If the market for these stickers gets too shaky, the whole kitchen might stop cooking clean energy, which is bad news for our planet's future.
This paper is like a detective story where the author, Zhongying Zhang, investigates the financial health of this "Green Certificate" market in China. The goal is to figure out if the market is stable enough to keep renewable energy growing or if it's about to crash. The study looks at two main things: how the prices and trading volume behave (the "Market Dimension") and how risky the money side is for the people buying and selling (the "Financial Dimension").
The investigation reveals a market that is growing fast but is also a bit wobbly. First, the prices are jumping around. Between April and June 2025, the average price of a certificate climbed from 2.31 yuan to 3.40 yuan. That's a big leap, with one month seeing a massive 63.24% increase! But here's the twist: the market loves "fresh" certificates and hates "old" ones. Certificates from the new production year (2025) are hot, with prices soaring from 4.12 yuan to 6.48 yuan. Meanwhile, certificates from 2023 or earlier are losing their value fast, dropping as low as 0.33 yuan. It's like having a brand-new iPhone versus an old one; the new one is worth a fortune, while the old one is barely worth the battery.
Even though more people are trading (the volume went up to 50.59 million certificates in June), the market isn't as deep as it should be. The author describes this as a "liquidity paradox." Imagine a crowded party where everyone is shouting to trade, but there are only a few people actually willing to buy or sell at a fair price. The "bid-ask spread" (the gap between what sellers want and what buyers will pay) stayed wide at an average of 0.85 yuan, meaning it's still expensive and difficult to trade quickly without losing money.
On the financial side, the risks are stacking up. The market is dominated by a few big players; the top five entities hold more than 60% of the certificates. This is like a game where five friends control almost all the cards, making the game risky if one of them decides to quit. The study found that the chance of these big players defaulting (not paying up) is rising. When you combine this with the fact that the rules keep changing (policy uncertainty) and it's getting harder to get loans (tightened credit), the overall "financial risk score" for the market went up from 0.45 to 0.58. This suggests the market is moving from a medium risk level to a medium-high risk level.
The paper concludes that while the Green Certificate market is doing its job of moving money toward clean energy, it's currently a bit of a rollercoaster. The prices are volatile, the trading pool is shallow, and the rules are uncertain. The author suggests that to keep the renewable energy train moving, we need to make the market deeper, spread out the power so it's not held by just a few people, and make the government rules clearer and more stable. Without these fixes, the financial risks could get in the way of saving the environment.
