*3.1. Analysis of Current Situation of Energy Saving and Environmental Protection Information* 3.1.1. Quantitative Distribution of ESEP Information

Sorting out the quantity, quality and content of ESEP information released by listed companies in the energy industry is helpful for us to grasp its development status and trends as a whole. In order to investigate the quantity of ESEP information release, this study provides statistics on the ESEP information release of sample companies from 2006 to 2017, and the year-by-year change trend is shown in Figure 3.

**Figure 3.** Quantity distribution of energy saving and environmental protection information disclosure.

As can be seen from Figure 4, the amount of ESEP information released in the energy industry showed a steady increasing trend during 2006–2017, but the release rate was still low. From 2006 to 2017, only 42.44% (N = 59) of enterprises in the energy industry released ESEP-related information reports (378 social responsibility reports/sustainability reports/employee responsibility reports), and 56.12% (N = 78) of enterprises did not release any ESEP-related information reports during this period. This shows that regular release of ESEP information has gradually become the consensus of listed companies in the energy industry, but there is still a big gap between the development of the national strategy of "beautiful China" and "healthy China". After further concluding ESEP related information of the company, it can be found that the central state-owned enterprises ESEP information release quantity (45.41%) was significantly better than that of local state-owned enterprises and private enterprises, reflecting that the central state-owned enterprise society responsibility consciousness is stronger and ESEP management level is higher, but the local state-owned enterprises and private enterprises release quantity remains to be further improved.

#### 3.1.2. Industry Distribution of ESEP Information

This study further provides statistics on the industry of the company releasing ESEP information. It can be seen from Table 3 that different industrys' nature leads to great difference in the release rate of ESEP information. The oil and gas extraction industry has the highest release rate (80.00% in the last three years), while the gas production and supply industry has the lowest release rate (25.57%).
