Against the background of economic globalization and domestic deepening reform in the new era,it is of great significance to establish the basic position of competition policy in the new era for the overall work of comprehensively deepening reform,comprehensively governing the country by law and transforming the strategy of economic development.This paper introduces the basic connotation and great significance of China's competition policy in the new era,and on this basis analyzes and summarizes the feasible legal path of China's competition policy,which focuses on the construction of the fair audit system is analyzed,in order to boost China's economic development.

Bi-level optimization based two-stage market clearing model considering guaranteed accommodation of renewable energy generation

The existing electricity market mechanisms designed to promote the consumption of renewable energy generation complicate network participation in market transactions owing to an unfair market competition environment,where the low cost renewable energy generation is not reflected in the high bidding price of high cost conventional energy generation.This study addresses this issue by proposing a bi-level optimization based two-stage market clearing model that considers the bidding strategies of market players,and guarantees the accommodation of renewable energy generation.The first stage implements a dual-market clearing mechanism that includes a unified market for trading the power generations of both renewable energy and conventional energy units,and a subsidy market reserved exclusively for conventional generation units.A re-adjustment clearing mechanism is then proposed in the second stage to accommodate the power generation of remaining renewable energy units after first stage energy allocations.Each stage of the proposed model is further described as a bi-level market equilibrium problem and is solved using a co-evolutionary algorithm.Finally,numerical results involving an improved IEEE 39-bus system dem-onstrate that the proposed two-stage model meets the basic requirements of incentive compatibility and individual rationality.It can facilitate the rational allocation of resources,promote the economical operation of electric power grids,and enhance social welfare.

Driving Factors, Effect Analysis and Countermeasures of the Development of China’s Live Broadcast Platform

The outbreak of coronovirus-19 epidemic has an unprecedented impact on economic and social development.Many traditional industries have stopped at one time,but the platform economy which is based on digital technology has accelerated its development and become a new driving force of China’s economic growth.As a new type and mode of business,live broadcast has grown rapidly with unique transmission advantages in this special environment,which not only meets the“no contact”demand during the epidemic situation,but also promotes the integration of online and offl ine.The development of live broadcast platform not only energizes the traditional industry,but also opens up the new growth space of China’s economy,expands the new fi eld of labor and employment,and plays an important role in rural revitalization and overcoming poverty.As a new form and model of business in recent years,the live broadcast platform needs the active guidance and support of the government,and needs to strengthen supervision and governance to promote its healthy,orderly and sustainable development.
