理论上认为,资源性资产具有收益能力,进而推知资源开采企业存在超额收益率。验证这一理论结论,可以计量评价资源开采企业的真实收益,会为资源会计准则、资源收益分配和资源税费改革制度的制订和完善提供坚实基础。本文在ElSerafy相关理论的基础上,提出了基本的研究假设,并使用我国采掘类上市公司2001-2005年的财务会计资料对上述问题进行了实证研究。经验数据表明:我国资源开采企业的收益率超过其他行业,存在超社会平均收益率;从配对样本的检验来看,其收益率仍然是偏高的,如总资产收益率要高出约4个百分点。根据这一结果,笔者提出了资源会计准则完善与创新的初步建议。
Theoretically, resource assets have profitability, and it is inferred that there are excess returns in resource mining companies. Validation of this theoretical conclusion can measure and evaluate the real benefits of resource mining companies, and provide a solid foundation for the formulation and improvement of resource accounting standards, resource income distribution, and resource taxation and fee reform systems. Based on ElSerafy’s related theories, this paper puts forward the basic research hypothesis, and uses the financial accounting data of China’s listed companies during 2001-2005 to conduct empirical research on the above issues. Empirical data show that: China’s resource mining companies have higher returns than other industries, and there is a super-societal average rate of return; from the perspective of a paired sample test, its yield is still high, such as total assets return rate is higher by about 4 percentage point. Based on this result, the author proposes preliminary suggestions for the improvement and innovation of resource accounting standards.
