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

Under the rapid growth scenario with the implementation of supply-side structural reforms, China's potential economic growth rate will reach an average of 6.5% and 5.8% respectively in the 13th Five-year Plan (2016-2020) and 14th Five-year Plan (2021-2025) periods. These rates are 0.2 and 0.3 percentage points higher, respectively, than that under the baseline scenario with the inertia of historic trends. In implementing supply-side structural reforms, China must transform governmental functions, break monopolies, create a comprehensive competitive market environment, foster the creation of pro-innovation mechanisms, refocus on quality and efficiency, and raise capital utilization and labor productivity.展开更多

China lags far behind advanced economies such as the United States, Germany and Japan in terms of the quality of transport infrastructures except railroad," electricity infrastructure is insufficient and service efficiency needs improvement; ICT infrastructure requires all-round upgrade and gaps in Internet bandwidth are striking. This paper suggests that, based on the needs of supply-side structural reform, China must reform its investment and financing systems to enhance the efficiency of infrastructure investment. Efforts must be made to enhance air transport and port infrastructure to support industrial upgrade; to develop the energy Internet to address emerging demands; and to forge a new generation of ICT infrastructure with industrial Internet as the priority to prepare China for the new round of industrial competition.展开更多

Firstly, the present situation of grain production is analyzed, and the problems facing the structural reform of grain supply side in China are analyzed from grain output and its import and export volume. Secondly, we use grey GM (1, 1) model to predict grain output and consumption, grain import and export volume and all kinds of grain crops output in China, and then analyze the future trend of grain production in China. Finally, we put forward construction of grain branding, rational allocation of grain planting varieties, construction of traceability system for grain production, further grain processing and development of “Internet agriculture” industrial model to promote structural reform of grain supply side.展开更多

The concept of green development refers to engaging in economic activities under the premise of fully protecting the environment and rationally utilizing resources. It is a good strategy to achieve harmony between man and nature on the basis of respecting the laws of nature. Based on the concept of green development, this paper attempts to explore the implementation path of structural reform of agricultural supply side from four aspects: industrial structure change, agricultural operation subject innovation, agricultural product brand construction and government safeguard measures. Agriculture is the foundation of the national economy.Effectively solving the obstacles in agricultural development and realizing agricultural modernization is of great value for improving China’s overall economic level, maintaining social stability and increasing farmers’ income.展开更多

The main reason why the focus shifts from changing EDM to reforming the supply-side structure lies in the fact that structural reform boosts the transformation of EDM, and only by accomplishing the former will the latter be realized. Today SRSS is faced with challenges like different ideologies, insufficient conditions and backward regulations. It should be led by the Five Major Development Concepts proposed by President Xi Jinping, "Innovation, coordination, greenness, openness and sharing," and the "supply-side" and "demand-side" must be simultaneously propelled.展开更多

Under the new normal, Zhejiang s agricultural development shows new characteristics and new trends of speed change, structural optimization, and power conversion, and meteorological services for agriculture have stronger demands, higher requirements, and heavier tasks. The socialization of meteorological services is a new type of system arrangement for the provision of meteorological services, and aims to provide high-quality and efficient meteorological service products for the public and promote the equalization of basic meteorological services in urban and rural areas. In this study, through research on the socialization of grassroots meteorological services in a new situation, a new way of the government to provide public weather services is proposed, and a mechanism of the government to purchase public meteorological services is established;social resources and forces are organized and guided to develop the innovation system and mechanism of public weather services, and social resources are fully mobilized to meet the demand for meteorological services in the process of agricultural supply-side structural reform.展开更多

The mismatch is exhibited at the supply side and arises from structural contradictions and must be addressed through reforms. Supply-side structural reforms can be analyzed at the levels of firms, industries and government to arrive at theoretical and systematic conclusions that offer practical guidance. Based on this perspective, this paper proposes policy recommendations on how to deal with zombie firms, reduce cost for manufacturing companies, deepen SOE reforms, eliminate overcapacity, implement "Made in China 2025" and Internet+ strategies, promote Beijing-l^anjin-Hebei integrated development, as well as develop the Yangtze River Economic Belt and the old industrial bases of the northeast.展开更多

A proper understanding of the proposal is crucial to the implementation of the reform which should be based on the backgrounds of macroscopic reform and cultural development of the country as well as the need for theoretical innovation. The reform should be carried out with a clear understanding of China's current conditions, a clarification of the reform thinking, the similarities and differences of supply–side structural reforms between the cultural and the economic sectors, as well as an analysis of issues related to the "supply–side" and "structure" in the cultural sector. Concerted efforts from the government through guidance, and market entities through operation should be made to apply appropriately to the reform principle of "unity of doubles effects." Innovations, especially those in technology and institutions, should be promoted as a new momentum to drive cultural development. Concerted efforts from the government and enterprises should underpin optimal supply and a mechanism for competition should be established to ensure effective supply in the cultural sector. In the meantime, the upgrading of demand should be used as a new guidance for effective supply and investment should be oriented to supplement the need for public cultural services. Attention should be paid to a satisfaction–oriented approach to fill the gaps in cultural consumption. For the cultural industry and undertakings, it is now the prime time which brings along great opportunities for development and challenges for reform. From now on the cultural sector should seek its development from transformation and upgrading. Supported by the central government through policy incentives and driven by technological innovations and the capital markets, the cultural industry will maintain stable growth for a relatively long period. In the implementation of supply–side structural reform in a well–organized and all–round way, governments, markets, enterprises, and the industry should each perform their functions and make concerted efforts for innovation to jointly promote the sound development and sustainable growth of the cultural sector.展开更多

The emergence of digital technology has brought new impetus to optimize the layout of industrial structures and transform the old and new kinetic energy. Combined with the 14th Five-Year Plan and the requirements of domestic and international dual-cycle development, we construct an evaluation index system for the efficiency of industrial supply-side structural reform from the five dimensions of benefit improvement, innovation-driven, structural optimization, ECO development, and people’s liveli-hood benefit. Based on the data of Guizhou and Sichuan province from 2010 to 2019, the efficiency of industrial supply-side structural reform in Guizhou from the horizontal and vertical perspectives is evaluated by using the entropy weight TOPSISI model, and policy suggestions for industrial development in Guizhou are put forward. Results show that:(1) the level of industrial supply-side structural reform in Guizhou was on the rise since 2015, but the development rate had slowed in the past two years, and the gap was obvious with Sichuan;(2) there is a problem of insufficient development imbalance in Guizhou, which is lagging in four aspects, including benefit improvement, innovation-driven, ECO development, and people’s livelihood benefit.展开更多
文摘In recent years, a lot of corporate defaults have had an impact on the capital market. 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 reform should be carried out with a clear understanding of China's current conditions, a clarification of the reform thinking, the similarities and differences of supply–side structural reforms between the cultural and the economic sectors, as well as an analysis of issues related to the "supply–side" and "structure" in the cultural sector. Concerted efforts from the government through guidance, and market entities through operation should be made to apply appropriately to the reform principle of "unity of doubles effects." Innovations, especially those in technology and institutions, should be promoted as a new momentum to drive cultural development. Concerted efforts from the government and enterprises should underpin optimal supply and a mechanism for competition should be established to ensure effective supply in the cultural sector. In the meantime, the upgrading of demand should be used as a new guidance for effective supply and investment should be oriented to supplement the need for public cultural services. Attention should be paid to a satisfaction–oriented approach to fill the gaps in cultural consumption. For the cultural industry and undertakings, it is now the prime time which brings along great opportunities for development and challenges for reform. From now on the cultural sector should seek its development from transformation and upgrading. Supported by the central government through policy incentives and driven by technological innovations and the capital markets, the cultural industry will maintain stable growth for a relatively long period. In the implementation of supply–side structural reform in a well–organized and all–round way, governments, markets, enterprises, and the industry should each perform their functions and make concerted efforts for innovation to jointly promote the sound development and sustainable growth of the cultural sector.

文摘In the era of the digital economy, great changes have taken place in the production and trading of enterprises. The emergence of digital technology has brought new impetus to optimize the layout of industrial structures and transform the old and new kinetic energy. Combined with the 14th Five-Year Plan and the requirements of domestic and international dual-cycle development, we construct an evaluation index system for the efficiency of industrial supply-side structural reform from the five dimensions of benefit improvement, innovation-driven, structural optimization, ECO development, and people’s liveli-hood benefit. Based on the data of Guizhou and Sichuan province from 2010 to 2019, the efficiency of industrial supply-side structural reform in Guizhou from the horizontal and vertical perspectives is evaluated by using the entropy weight TOPSISI model, and policy suggestions for industrial development in Guizhou are put forward. Results show that:(1) the level of industrial supply-side structural reform in Guizhou was on the rise since 2015, but the development rate had slowed in the past two years, and the gap was obvious with Sichuan;(2) there is a problem of insufficient development imbalance in Guizhou, which is lagging in four aspects, including benefit improvement, innovation-driven, ECO development, and people’s livelihood benefit.
