Research on Online Education of Talent Training and Young Teacher Growth Based on Multimedia Technology

Information technology education has played a more important role under the background of“Internet+”.However,a combination of education and information technology is only limited between online teaching platforms and massive open online courses(MOOC).This paper proposes a visual teaching system based on cloud computing and big data techniques via combing virtual and real techniques online and offline to provide rich teaching resources for students.It can also use the digital human-computer interaction answering function to address students’questions.Additionally,it can provide a medium for young teachers to quickly improve their professional teaching skills.This paper aims to achieve a multimedia system via integrating“Internet+”technology with education to help improve talent training and abilities of young teachers.

Properly Understanding Supply–side Structural Reform in the Cultural Sector

The proposal of supply–side structural reform in the cultural sector is based on theoretical inspiration from the economic sector and actual issues in the cultural sector. 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.

Renminbi in Africa： Progress and Challenges

One important aspect of China-Africa financial cooperation is to expand the renminbi's use in bilateral economic and trade exchanges. Despite progresses made, the renminbi's current use in Africa has many limitations in terms of size and scope of functions.

China’s grain production: status and prospects

In this paper, we first look back at China’s grain production since reform and opening up and review the main factors of grain production at different stages. Secondly we find that the improvement of the per unit yield has become a major factor in the increase of grain production, and that corn has become a major grain production support variety; compared with the other varieties, paddy rice is most vulnerable in production; grain production has increasingly become dependant on scientific and technological progress and the role of infrastructure. Thirdly, the transformation of low-yielding fields in the future, the development of reserve land resources and acceleration of scientific and technological progress – these factors together promote China's great potential for grain production; but through adjusting variety structure to promote grain production is nearly impossible. Finally, the main constraints of China’s future grain production are as follows: reduction of arable land and water shortages is becoming increasingly constrained; agricultural comparative advantage is low; opportunity cost is high and accelerating at the same time; and the uncertainties of (1) whether the agricultural inputs by government at all levels of can significantly increase the intensity; (2) whether support of the reform of grain production and systems can achieve breakthrough; and (3) whether the risk of the development of grain production can be effectively prevented. On this basis, we draw the relevant conclusions and policy recommendations.

Classification of Growth Clubs and Convergence: Evidence from Panel Data in China, 1981-2004

This paper uses provincial panel data to examine club convergence in China during 1981- 2004. We estimate the province-specific initial technology level, A（O）, and classify the Chinese economy into ＂developed club＂ and ＂underdeveloped club ＂ based on the economic characteristics of A（O）, instead of on geographical location. We find significant evidence of conditional convergence across provinces, and that the convergence speed in the developed club is faster than that in the underdeveloped club. We also find that.＂ （i） human capital accumulation contributes more than physical capital does to club convergence,＂ （ii） there is a positive correlation between infrastructure and growth convergence at the national level and within the developed club, while the spillover effect of infrastructure has not been developed in the developing club; and （iii） the effect of economic openness on convergence is tiny, and insignificant across and within clubs.

Social-Justice Principles Should Apply in Public Expenditure

In the absence of household data, this article attempts to convert variables to build a public expenditure incidence assessment model by using middle-level data to analyse and explain the disequilibrium between the rich and poor in their public expenditure benefits. By using China's provincial data to validate this model, we have found a lack of sufficient public security services for the rich; an increase in cultural, educational and healthcare provisions as well as social relief for the poor over recent years; a lack of social security services for the poor; the availability of immediate economic services, but a lack of those with long-term benefits to the poor; the provision of subsidies to the rich and the furnishing of special-purpose services and support to the poor. The disparity in the provision of public services is primarily attributable to economic strength, economic deficiency, public preference and the government financial transfer payment mechanism. Last but not least, the paper presents some policy recommendations.

DISTRIBUTING ENERGY AS NEEDED A system anchored with clean energy could be an effective way to achieve green low-carbon energy transformation

China has a big demand for energy but limited energy resources.To achieve green and low-carbon development,it must accelerate construction of a distributed energy system(DES)with high energy utilization efficiency and low environmental pollution,which will be a tremendously significant step towards the country’s goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060(the“3060”target).

Manager Mobility and Private Equity Syndications from the Perspective of Coupling Networks:Evidence from China’s Private Equity Industry

This study explores whether manager mobility can influence syndications between private equity(PE)firms by constructing coupling network models.Using data from China’s private equity market from 1993 to 2017,we found that driving forces,resistant forces,and network structure play significant roles in determining resource flows between PE firms.Specifically,driving forces indicate that managers moving from domestic and foreign PE firms to state-owned PE firms are more likely to induce syndications.Furthermore,if the manager is promoted when changing jobs,mobility is likely to enhance the flow of resources.Resistant forces indicate that increased geographical distance reduces syndications.As for the influence of structure,if managers leave PE firms with higher status,they are more likely to induce syndications.This study contributes to the coupling network literature by providing a clarified three-factor framework.By exploring the characteristic of managers in state-owned private equity firms,we specified the syndication theory in China.This study can help private equity firms hire valuable managers and expand syndication networks in practice.

Study on Optimization of Passenger Flow at a Metro Station Based on AnyLogic-Case Study of Youfangqiao Station of Nanjing Metro Line 2

In this study,simulation software AnyLogic was used to establish a station simulation model for a metro line.First,a basic model of the environment of the metro station was drawn,and accordingly,reasonable assumptions and simplifications were proposed.Then,a diagram of the passenger walking path was created and the simulation variables and functions for passenger flow management were designed.Considering Youfangqiao Station of Nanjing Metro Line 2 in China as an example,the real passenger flow data of this station were statistically analyzed.To simulate the station passenger flow management,input parameters such as the passenger space diameter,passenger flow generation rate,delay rate of automatic fare collection equipment and security check machine,and the number of gates were considered.Passenger flow management was optimized for the morning and evening peak periods,and reasonable suggestions were proposed based on the optimization results,providing a theoretical basis for the construction planning and pre-evaluation of station operation capacities of urban rail transit systems.
