Assessing the Implementation of Local Emission Trading Schemes in China T when the regulated firms actively manage their compliance after the disclosure of verified emission and before the submission deadline of allowances valid for year T-1 (Alberola, Chevallier, and Chèze 2008). There are limited empirical studies on the price dynamics of the piloting ETSs in China. Among a few recent empirical studies that did focus on CO 2 emission allowance (CEA), Zeng et al. (2017), Zhang and Zhang (2016), and Fan and Todorova (2017) examined the relationships between CEA price and energy prices. Zeng et al. (2017) employed a structural VAR approach showing that during April 2014–November 2015, coal price had a significant and positive impact on Beijing CEA price within a short period, but it became negative after two days when firms started to substitute coal with less carbon-intensive energy sources or use carbon-reduction measures. Based on a quantile regression method, Zhang and Zhang (2016) argued that oil price had a slight positive impact on the Shanghai CEA price, consistent with the substitution effect theory. Fan and Todorova (2017) investigated into the response of emission allowance price to energy prices and macroeconomic indicators in Beijing, Shenzhen, Guangdong and Hubei from the launching dates to December 2016. The results showed that Hubei CEA price was weakly related to natural gas price, while Guangdong CEA price had a significant positive relation with oil price. However, overall, the empirical studies on the influence from energy prices to CEA prices have been scarce and scattered. Given that there are still few empirical studies on the prices of China’s CEA and considering that ETS will continue to play an important role in reducing CO 2 emissions in China, this study aims at examining the price dynamics of CEA, with a focus on the relations between energy markets and ETS markets. The rest of the article is organized as follows. Section 2 details the data and method. Section 3 starts with the descriptive analysis of the CEA price and trading volume data, following by co-integration tests and multivariate regressions to examine the relationship between energy prices and CEA price. Section 4 presents concluding remarks and policy implications of the findings. 2. Data and Method 2.1. Data We collected the daily CEA price data and daily transaction volume data from the website (www.tanpaifang.com) that compiles the market data published by Emission Exchanges of the seven ETS pilots. The website was created in 2012, organized by the Zhongke Carbon Information Technology Research Institute, providing data, regulatory information and consultancy about ETS. As Chinese ETS allows for only spot trading, all price data collected are closing spot trading price data. The market data of China’s seven piloting ETSs can also be found from the website (www. chinacarbon.net.cn) organized by Climate Limited, which is a UN-accredited online media company.
