Study on China’s Industrial Competitiveness - Original PDF
نویسندگان: خلاصه: International competitiveness, which rose in the 1980s and became a hot spot in the world in the 1990s, driven by the economic globalization, information technology revolution and the rapid development of high-tech industry, has gradually become an important research field and attracted the attention of all countries in the world. Economic competition, in the final analysis, is industrial competition. The overall economic competitiveness of a country or region is determined by the competitive- ness of its main industries. With the rapid development of economic globalization and the promise of China to accede to WTO, how to deal with the open international market become the concerned issue of corporate, industrial, government, research institution and the public. China has strong competitiveness in the market potential and human resource. But from 1994 to 2006, the international competitiveness of China was ranked in around 28th dues to the weakness of enterprise competitiveness. Industry competitiveness is the biggest bottleneck for China to improve the international competitiveness
Institutions and Economic Development - Original PDF
نویسندگان: خلاصه: Arguably, the most important question in Economics and probably in social sci- ence is ‘why are some nations rich, and others poor?’ Not only is this an interesting theoretical question, it has practical relevance to human living. According to the World Bank, 9.4% of the global population are still living below the poverty line of US$1.90-a-day (The World Bank, 2020). Understanding the factors that con- tribute to a nation’s economic development will help clarify the path forward for development policymaking. This Companion will explore the phenomenon of economic development and review the leading theories explaining why it is present in some nations and absent in others. Such a task will necessarily require one to be selective, as development studies is a complex field involving various disciplines with no easy answers. Even today, development economists debate the causes of development and how to foster it in poor nations, if at all possible. Before diving into development theories, however, this chapter will first define some basic concepts and establish general facts. The subsequent sections will pin down the concept of ‘economic development’ and provide factual information about changes in living standards over time. We show that a real and sustained improvement in living standards has indeed occurred—called the ‘Great Enrich- ment’ which started in the late eighteenth century onwards. Accordingly, we explore the deep determinants of this development and focus on the rules and values in society which have facilitated this improvement in living standard
China’s Food Security - Original PDF
نویسندگان: خلاصه: Our planet was formed about 4.5 billion years ago, while human beings evolved 2 or 3 million years ago, and the history of growing grain began more than 10,000 years ago. Following the agricultural and indus- trial civilizations, we are currently in the age of information civilization. Humans have landed on the moon, soared freely in space, but yet to get rid of hunger! Human history has witnessed several wars over food and land. Many nations prospered because of food, but many regimes perished because of food shortages. Being a primary human need, food has always been an influential factor for the survival and health of human beings, and a prerequisite for peace and stability of the world. Based on our history and experience, food is essential to human beings, to economic devel- opment, to social stability, and to national autonomy. Food is also a bargaining chip for diplomatic negotiations and a tool for international competition
Contemporary Economic Issues in Asian Countries: Proceeding of CEIAC 2022, Volume 2 - Original PDF
نویسندگان: خلاصه: CSR is the way in which corporations attribute their resources to take responsibility in order to improve the society and environment for a long term which goes beyond the merely economic strategy and legal requirements. It is one of the important factors affecting firm performance. Along with the shift from “traditional CSR” to “modern CSR,” our study assesses the impact of online CSR disclosure on firm performance of listed banks in Vietnam to fill the research gap both in theory and in experimental application. Content analysis and Pool-OLS regression methods are applied to calculate and evaluate the results of testing the research hypotheses. The results show that online CSR disclosure produces a positive effect on firm perfor- mance in terms of ROA indicator and the online disclosure of CSR information can produce protection shield to reduce the negative impacts of uncertainty events as COVID-19. Our study provides empirical suggestion that managers should utilize CSR as a strategic action to gain higher firm performance. This result implies that in terms of policy, it is necessary to establish standardized systems that guide and control CSR practices to enhance the effectiveness of CSR disclosure
Bioeconomy Theory and Practice - Original PDF
نویسندگان: خلاصه: Our universe started with Big Bang approximately 13.5 billion years ago. Earth formed 4.6 billion years ago. Simple organisms emerged 3.8 billion years ago. Homo habilis appeared in Africa 2.5 million years ago and Homo sapiens lived 70,000 years ago.1 The agricultural revolution began to accelerate 12,000 years ago, the first industrial revolution began 200 years ago, and the first information revolution started 70 years ago. To date, human society is about to enter a new era, having gone through transformations such as hunting and gathering, agricultural plantation, and large-scale industrial manufacturing and having experienced agricultural, industrial, and information civilizations
High temperature strain of metals and alloys: physical fundamentals - Original PDF
نویسندگان: خلاصه: Creep and fatigue are the most prevalent causes of rupture in superalloys, which are important materials for industrial usage, e.g. in engines and turbine blades in aerospace or in energy producing industries. As temperature increases, atom mobility becomes appreciable, affecting a number of metal and alloy properties. It is thus vital to find new characterization methods that allow an understanding of the fundamental physics of creep in these materials as well as in pure metals. Here, the author shows how new in situ X-ray investigations and transmission electron microscope studies lead to novel explanations of high-temperature deformation and creep in pure metals, solid solutions and superalloys. This unique approach is the first to find unequivocal and quantitative expressions for the macroscopic deformation rate by means of three groups of parameters: substructural characteristics, physical material constants and external conditions. Creep strength of the studied up-to-date single crystal superalloys is greatly increased over conventional polycrystalline superalloys. From the contents: - Macroscopic characteristics of strain at high temperatures - Experimental equipment and technique of in situ X-ray investigations - Experimental data and structural parameters in deformed metals - Subboundaries as dislocation sources and obstacles - The physical mechanism of creep and the quantitative structural model - Simulation of the parameters evolution - System of differential equations - High-temperature deformation of industrial superalloys - Single crystals of superalloys - Effect of composition, orientation and temperature on properties - Creep of some refractory metals For materials scientists, solid state physicists, solid state chemists, researchers and practitioners from industry sectors including metallurgical, mechanical, chemical and structural engineers.
Phase Transformations of Elements Under High Pressure - Original PDF
نویسندگان: خلاصه: The study of transformations of materials under high pressures promises to yield modifications with important applications in materials science and other fields including, by way of example, the dense metallic modification of hydrogen possessing extremely high superconducting properties. This work presents recent theoretical and experimental information gathered on phase diagrams of 96 elements. Data is presented on first- and second-phase transitions, melting lines, crystal structures of the stable and metastable phases, important phase properties such as the Curie and Neel temperature, and the superconducting temperature. Information is provided on elements' liquid state, amorphization, and metallization. Temperature-pressure diagrams are given for most of the elements.
