As the study suggested that the basic position of the primary forestry industry should be strengthened and promoted, deep processing capacity and resources utilization of the secondary industry should be further developed, and the leading role of the tertiary industry should be further enhanced in accordance with the low carbon concept.展开更多

How to prevent corporate default risks has become an important topic of concern for the academic community, enterprises and the government. We took China’s A-share listed companies from 2012 to 2018 as a sample, and used the double difference method to analyze the impact of supply-side structural reforms on corporate default risks. We found that supply-side structural reforms have reduced the risk of corporate default, and the inhibitory effect has gradually increased. In the relationship between supply-side structural reforms and corporate default risks, corporate financing capabilities have played an intermediary role. Supply-side structural reforms can improve the company’s endogenous financing capabilities, thereby reducing the risk of corporate default. However, we also found that the mediating effect of a company’s exogenous financing capability is not significant. At the same time, the regression results show that the digital economy can play a regulatory role. It can not only actively regulate the relationship between supply-side structural reforms and corporate default risks, but also mediate the mediating effect of corporate endogenous financing capabilities. The results of this article provide some evidence for the synergy between supply-side structural reforms and the digital economy.展开更多

However, the effectiveness of this model of industry-dominate industrial structure and the role of industrial structure pattern in promoting regional economic growth are yet to be researched. By using shift-share analysis method, we judge the importance of factors of industrial structure in regional economic growth of Jiangsu Province, and point out that factors of industrial structure are not the dominant forces in economic growth of Jiangsu Province; among the contributions of three industries to economic growth of Jiangsu Province, the contribution of the primary industry is greatest, followed by the contribution of secondary industry and the contribution of tertiary industry successively; real estate industry makes the greatest contribution to economic growth of Jiangsu Province; financial industry and construction industry make relatively small contributions; the potential of industry needs to be further developed. In the process of economic development of Jiangsu Province, the industrial structure is yet to be further optimized so as to give play to the role of industry in promoting the development of Jiangsu Province.展开更多

However, in order to take control of the state-owned shares in the end making the state ownership economy become the principal position and to enlarge the scale of state-owned shares, which guides the common development with the non-public sectors of the economy, how to determine the proportion of state-owned shares? Under the background of the mixed ownership reformation, the article explains the mixed ownership by explaining how to enlarge the state-owned assets controlling scale and how to improve the stateowned company 'economic effi ciency and how to protect the interests of small shareholders. The final conclusion is that the SASAC should use the thinking of relative holdings, instead of the absolute control thinking, and should make use of the games among the large shareholders and the pyramidal ownership structure to make the pattern of ownership diversify.展开更多
