Comparative Study of Magmatism in East Pacific Rise Versus Nearby Seamounts:Constraints on Magma Supply and Thermal Structure Beneath Mid-ocean Ridge

Major elements of 2202 basalts from the East Pacific Rise （EPR） and 888 basalts from near- EPR seamounts are used to investigate their differences in magma crystallization pressures and mantle melting conditions. Crystallization pressure calculation from basalts with 5.0wt%〈MgO〈8.0wt % shows that magma crystallization pressures beneath near-EPR seamounts are positively and negatively correlated with Nas and Fes, respectively. However, these correlations are indistinct in axial lavas, which can be explained by chemical homogenization induced by extensive mixing processes. In each segment divided by major transforms and over-lapping spreading centers （OSCs）, near-EPR seamount lavas have higher magma crystallization pressures, higher Fes and lower Nas than the EPR lavas, which indicate cooler lithosphere, lower degrees and shallower melting depths beneath near-EPR seamounts than the EPR. The correlations between magma crystallization pressures and melting conditions beneath near-EPR seamounts imply that the source thermal state controls the melting degree and melt flux, and then melting process controls the shallow lithosphere temperature and magma crystallization depth （pressure）. The cooler mantle sources beneath near-EPR seamounts produce a lower degree of melting and a less robust magma supply, which results in a deep thermal equilibrium level and high magma crystallization pressure. The magma crystallization pressure decreases significantly as spreading rate of the EPR increases from ~80 mm/year in the north （16~N） to ~160 mm/year in the south （19~S）, while this trend is unobvious in near-EPR seamounts. This suggests that the magma supply controlled by spreading rate dominates the ridge crust temperature and magma crystallization depth, while the near-EPR seamount magma supply is not dominated by the axial spreading rate. Because most seamounts form and gain most of their volume within a narrow zone of 5-15 km from ridge axis, they provide good constraint on magma supply and thermal structure beneath the EPR. High magma crystallization pressures in seamounts indicate dramatic temperature decrease from the EPR. The crystallization pressures of seamount lavas are well correlated with mantle melting parameters but in a blurry relationship with axial spreading rate. Despite the adjacency of the EPR and nearby seamounts, the thermal structure beneath the near-EPR seamounts are controlled by their own magma supply and conductive cooling, chemically and thermally unaffected by magmatism beneath the ridge axis.

Analysis on the Structure of Influencing Factors of Sustainable Supply Chain Implementation of Water Diversion Project

The systematic analysis of the hierarchical relationship among the factors affecting the sustainable supply chain implementation of water diversion projects has theoretical value and practical significance for the sustainable development of large-scale water diversion projects. Through the investigation of relevant literature, books, web pages, materials, and discussions with relevant experts and scholars, a total of 23 factors influencing the sustainable supply chain implementation of water diversion projects were identified. Then using ISM (Interpretative Structural Modeling Method) to analyze the causality of each factor, a multi-level hierarchical structure model was obtained. The results showed that: 1) The surface-level influencing factors of the sustainable supply chain implementation of the water diversion project mainly included 8 factors such as water-saving awareness and water-saving intensity in the diversion area, water quality, water pollution and other disasters, effective incentive mechanisms, etc., and surface-level influencing factors were directly related to the sustainable supply chain implementation of water diversion projects. 2) The indirect influencing factors of the sustainable supply chain of water diversion projects included 12 factors such as the water quality and quantity guarantee rate of the supply chain, the government’s enforcement of laws and regulations, water distribution, ecological compensation, and compensation mechanisms for residents in the water source area. Indirect influencing factor scan acts directly on the direct influencing factors, and intervening in the factors that can be controlled by humans is one of the important ways to improve the sustainable operation of water diversion projects. 3) The fundamental influencing factors for the sustainable supply chain implementation of water diversion projects included three factors: Resettlement policy, government financial support, and sound laws and regulations. Deep influencing factors had multi-channel influence and controllability, and intervening in them was the main means to improve the sustainable operation of water diversion projects.

Structures of Textile-apparel Supply Chain: Concepts and Cases

In recent years, supply chain management (SCM) has been in popularity as a new management philosophy for all industries, including textile and apparel industries. The textile-apparel supply chain is relatively complex because it encompasses many participants such as yarn manufa-cturers, fabric manufacturers, garment manufacturers and retailers. Although many scholars are engaged in rese-arching SCM in textile and apparel industries, a systematic classification of textile-apparel chain does not exist. The paper proposes three types of textile-apparel chain, nominated vertical integration chain, traditional sourcing chain and 3P-hub (third party as the hub) chain. Different coordinators exist in different types of chain. Three Hong Kong headquartered companies, Esquel Group, TAL Apparel Ltd., and Li & Fung (Trading) Ltd. are used as cases responding to each type of the structures respectively.

Supply-Side Structural Reform, Digital Economy and Corporate Default Risk

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 results of this article provide some evidence for the synergy between supply-side structural reforms and the digital economy.

Electrical characteristics of new three-phase traction power supply system for rail transit

A novel three-phase traction power supply system is proposed to eliminate the adverse effects caused by electric phase separation in catenary and accomplish a unifying manner of traction power supply for rail transit.With the application of two-stage three-phase continuous power supply structure,the electrical characteristics exhibit new features differing from the existing traction system.In this work,the principle for voltage levels determining two-stage network is dissected in accordance with the requirements of traction network and electric locomotive.The equivalent model of three-phase traction system is built for deducing the formula of current distribution and voltage losses.Based on the chain network model of the traction network,a simulation model is established to analyze the electrical characteristics such as traction current distribution,voltage losses,system equivalent impedance,voltage distribution,voltage unbalance and regenerative energy utilization.In a few words,quite a lot traction current of about 99%is undertaken by long-section cable network.The proportion of system voltage losses is small attributed to the two-stage three-phase power supply structure,and the voltage unbal-ance caused by impedance asymmetry of traction network is less than 1‰.In addition,the utilization rate of regenerative energy for locomotive achieves a significant promotion of over 97%.

Setting the Structural Reform of Supply-Side as the Focus and Shifting the Economic Development Model

To focus on SRSS during the 13th Five-Year Plan period(2016-2020) is a necessary response to the changes of the international economic environment and to China's goal of achieving the new normal in economic development. 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.

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.

In recent years,China’s sports industry has witnessed rapid development gradually forming an emerging strength in its Supply-side Structural Reform and thus increasingly being highlighted in the development of the nationa economy.Being integrated,society-based,green and sustainable,the sports industry is gaining popularity among the Chinese people.This paper studies the overall development of Chinese sports industry during the 12th FiveYear Plan period(2011-2015)and unveils the key achievements it made,such as the expansion of scale,the diversification of products and services,the improvement of industry policies,the apparent upgrading and optimization of the industry’s structure and its further integration with the Internet However,there are still some problems in the development of China’s sports industry&Chinese sports industry accounts for a fairly low proportion in the gross domestic product(GDP)and cannot yet compare with those of developed countries.Besides,given that its the sports services make up only a small share and that a supply-demand imbalance still exists in the sports products and services,its industrial structure requires further upgrading and optimization.In addition,failure to fully stimulate an innovation initiative restricts this industry’s further development.Targeting the bottleneck facing Chinese sports industry and corresponding path selection,this paper mainly analyzes its institutional mechanism reform,structural upgrading and layout product quality improvement and talent supply optimization.Based on the analysis,it is concluded that the development of Chinese sports industry is of great importance to China’s economic transformation,upgrading and healthy development and it echoes the call of Supply-side Structural Reform.

Supply-Side Structural Reforms of China's Industries

Supply-side structural reforms are structural adjustments and institutional reforms to address the mismatch between supply and demand and improve TFP. 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-Tianjin-Hebei integrated development, as well as develop the Yangtze River Economic Belt and the old industrial bases of the northeast.

The Supply-Side Structural Reforms——Adapting to and Leading China's New Normal

The Central Economic Working Conference proposed supplyside structural reforms which can be regarded as major innovations and necessary measures that adapt to and lead the new normal of economic development. The 13^(th) Five Year Plan is a critical period for the transformation of economic development patterns and economic restructuring, so clarifying the theoretical values and practical significances of the supply-side structural reforms, making a clear explanation of the scientific connotations and policy implications of these reforms from a scientific standpoint, and discussing concrete measures to promote the reforms against the background of the economic new normal not only has academic values but also has important practical implications. Viewed from the practical standpoint of China' s new normal and through analyzing the basic national conditions, this article proposes a roadmap for implementing the proposed reforms and points out that only by doing well in the hybrid operation of "addition, subtraction, multiplication and division", based on the framework of the "five policy pillars", an innovative path of the supply-side structural reforms with Chinese characteristics can be paved.

Research on the Socialization of Grassroots Meteorological Services in Agricultural Supply-side Structural Reform

In 2017, the No. 1 Document of the Central Committee proposed that "it is necessary to further promote agricultural supply-side structural reform, accelerate the cultivation of new kinetic energy for agricultural and rural development, and create a new situation in the construction of agricultural modernization". 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.

Analysis and Forecast of China’s Grain Supply and Demand Quality Grade Structural Balance

Based on the analysis of China’s grain production and demand quality grade, this paper uses the non-equidistance GM (1,1) model and the inference algorithm to predict the structural balance of the supply and demand grades of China’s four major grain crops. The results show that the supply and demand for wheat, corn and rice can maintain a quantitative balance. While, it’s difficult to achieve a quality grade balance in wheat and rice and keep a supply and demand balance in terms of quantity and quality of soybean. Simultaneously, the supply of premium grade corn is greater than the demand. The analysis and prediction results can reflect the existing structural balance matter of grain supply and demand at different quality grades in China, and provide theoretical basis for governments to formulate relevant policies.

China's Excess Oil Refining Production Capacity in the Background of the Supply Side Structural Reform

Through analysis of the current situation and newly-increased production capacity-of the oil refining industry of China, this Paper discusses both the continuous expansion trend and the serious excess of production capacity of the oil refining industry of China. Due to the entry of the Chinese economy into the new normal,the accelerated substitution of old energy by new energy and rigid restrictions composed of low carbon and environmental protection requirements, the oil demand of China will continue to increase overall, but the growth will obviously slow down. At the same time, the newly-increased production capacity in Shandong and coastal region will continuously expand, the supply and demand contradiction will intensify, and the structural excess production capacity of the oil refining industry of China will be prominent. It is suggested that the government should attach great importance to the production capacity of the oil refining industry at the macro level, and deeply carry forward the supply side structural reform, and that enterprises should speed up technical innovation,enhance regional and layout optimization, adapt to market changes and adjust product structure, control oil refining but increase chemical engineering, improve product quality and production efficiency, and constantly promote the international competitiveness of the Chinese petrochemical industry.
