Performance Measurement of Turkish and Chinese Manufacturing Firms: A Comparative Analysis  [PDF]
Nizamettin BAYYURT,Gokhan DUZU
Eurasian Journal of Business and Economics , 2008,
Abstract: The aim of this paper is to compare the relative efficiencies of manufacturing companies of China, one of the BRIC countries (BRIC: Brazil, Russia, India, China) that are expected to dominate the world economy in 2050s, and Turkey, that is an attractive emerging market (Morgan Stanley Index 2006) with great potential. We will determine the relative performances of Turkish and Chinese manufacturing firms using weight restricted Data Envelopment Analysis (DEA). Weights of inputs and outputs are estimated by canonical correlation analysis. Mean efficiencies of the firms of the two countries are compared by t-test. The results of DEA and statistical analyses indicate that Chinese manufacturing firms are highly efficient than Turkish manufacturing firms on average.
Chinese kangs and building energy consumption
YuGuo Li,Zhi Zhuang,JiaPing Liu
Chinese Science Bulletin , 2009, DOI: 10.1007/s11434-009-0129-z
Abstract: Chinese kangs are an integrated system for cooking, sleeping and heating in rural Northern China with more than 2000 years history. In 2004 there were 67 million Chinese kangs used by 44 million rural families or 174 million people. Chinese kangs store surplus heat from stove during cooking and releases it later for both home heating and localized bed heating. Such a widely used heating system has been rarely studied. Understanding kangs is important for developing new effective home heating systems for better energy efficiency and improving indoor air quality in Northern China. In this paper, we review and present some preliminary results from our field measurement and mathematical modeling, and discuss the development of Chinese kangs as related to future energy consumption in rural homes, and building energy consumption in China in general. We suggest that transition and new technologies for rural home heating in Northern China, i.e. the future of Chinese kangs, should be considered as the top priority in managing future building energy consumption in China.

International Journal of Digital Multimedia Broadcasting , 2011, DOI: 10.1155/2011/926363
Abstract: Smart grid, as an intelligent power generation, distribution, and control system, needs various communication systems to meet its requirements. The ability to communicate seamlessly across multiple networks and domains is an open issue which is yet to be adequately addressed in smart grid architectures. In this paper, we present a framework for end-to-end interoperability in home and building area networks within smart grids. 6LoWPAN and the compact application protocol are utilized to facilitate the use of IPv6 and Zigbee application profiles such as Zigbee smart energy for network and application layer interoperability, respectively. A differential service medium access control scheme enables end-to-end connectivity between 802.15.4 and IP networks while providing quality of service guarantees for Zigbee traffic over Wi-Fi. We also address several issues including interference mitigation, load scheduling, and security and propose solutions to them. 1. Introduction The smart grid is an intelligent power generation, distribution, and control system. It enhances today’s power grid with intelligence, bidirectional communication capabilities and energy flows [1]. These enhancements address the efficiency, stability, and flexibility issues that plague the grid at present. In order to achieve its promised potential, the smart grid must facilitate services including the wide-scale integration of renewable energy sources, provision of real-time pricing information to consumers, demand response programs involving residential and commercial customers, and rapid outage detection. All these tasks demand the collection and analysis of real-time data. This data is then used to control electrical loads and perform demand response. In order to obtain the full benefit of smart grids, their communication infrastructure must support device control and data exchanges between various domains which comprise the smart grid. The smart grid must be allied with smart consumption in order to achieve optimum power system efficiency. This necessitates the integration of smart buildings, appliances, and consumers in order to reduce energy consumption while satisfying occupant comfort. Building automation systems (BASs) already provide this intelligence, enabling computerized measurement, control and management of heating, ventilation, air-conditioning (HVAC), lighting, and security systems to enhance energy efficiency, reduce costs, and improve user comfort. Buildings consume 29% of all electricity generated in the United States [2]; therefore, the ability of BASs to communicate

Kevin Nagorny, Pedro Lima-Monteiro, Jose Barata, Armando Walter Colombo
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2017, DOI: 10.4236/ijcns.2017.103003
Abstract: The technological evolution emerges a unified (Industrial) Internet of Things network, where loosely coupled smart manufacturing devices build smart manufacturing systems and enable comprehensive collaboration possibilities that increase the dynamic and volatility of their ecosystems. On the one hand, this evolution generates a huge field for exploitation, but on the other hand also increases complexity including new challenges and requirements demanding for new approaches in several issues. One challenge is the analysis of such systems that generate huge amounts of (continuously generated) data, potentially containing valuable information useful for several use cases, such as knowledge generation, key performance indicator (KPI) optimization, diagnosis, predication, feedback to design or decision support. This work presents a review of Big Data analysis in smart manufacturing systems. It includes the status quo in research, innovation and development, next challenges, and a comprehensive list of potential use cases and exploitation possibilities.
A Review to the Development of Foreign Capital Manufacturing Industry in China: Looking forward to Made in China, 2025  [PDF]
Jiawan Xia
American Journal of Industrial and Business Management (AJIBM) , 2017, DOI: 10.4236/ajibm.2017.75045
Abstract: This paper argues China through the establishment of special economic zones at the beginning of reform and opening up, as well as the formulation of “super national treatment” and other preferential policies to attract foreign investment. To now have a large number of foreign manufacturing enterprises’ withdraw behind China’s contrast, is a reflection of China’s economy growing stronger, and is the inevitable result compatible with the “made in China 2025”. This paper hopes to help some enterprises to correctly understand the phenomenon of foreign investment. This paper reviews the different historical periods under the different performances of China’s policy on foreign investment to explore “made in China 2025” by the historic significance, but also shows good hope for the development of Chinese manufacturing industry.

The Size Distribution of Chinese Manufacturing Firms: From the Perspective of Industry Life Cycle  [cached]
Yanying CHEN,Li WANG,Gaofeng TIAN
International Journal of Economics and Finance , 2012, DOI: 10.5539/ijef.v4n7p67
Abstract: Using panel data of Chinese manufacturing firms between 2003 and 2008, this paper aims to examine the evolution of firm size distribution (FSD) as the industry goes through its life-cycle. The results reveal that during the life-cycle process, China’s manufacturing firms’ average size becomes larger then shrinks, and the degree of firm size heterogeneity and industry concentration increases all the time. Empirical results also indicate that the change rate of FSD is affected by firms’ net entry rate into industry. When net entry rate is higher, average firm size’s growth rate is smaller, while size heterogeneity and industry concentration rises more dramatically.

International Transaction Journal of Engineering, Management, & Applied Sciences & Technologies , 2011,
Abstract: This study discussed a comparative study on building structural construction between Traditional Chinese Building and Kampung Laut’s Old Mosque (KLOM). The objective is to identify the level of influence of the traditional Chinese building structural construction to the structural construction of KLOM. The result is one of the ways to support an argument using evidence on the building construction that the religion of Islam was spread to South East Asia from China and Indochina (East) in contrast to most arguments from Arabian region and India (West). The scope was limited to the analysis of the building structures. There were 10 factors were identified as the measurable factors in the literature study. The results showed that there are influences from traditional Chinese construction on building structures of KLOM.

Abstract: Economic transition, which can be conceptualized a triple process of marketization, globalization and decentralization, has significantly shaped China's economic geography. Marketization introduced market competition and allowed market forces to distribute resources, stimulating firms to locate along the line of comparative advantages. Economic globalization further opened the Chinese economy to international competition, encouraging the geographical concentration of Chinese industries. Regional decentralization however induced fierce interregional competition, resulting in local protectionism and rational imitation of industrial policies and therefore stimulating the geographical dispersion of Chinese industries. As economic transition proceeds, there has been substantial spatial restructuring in Chinese manufacturing industries. Most industries experienced spatially dispersing process in the 1980s and have been increasingly agglomerated since the early 1990s. Chinese provinces had been diversifying their industrial compositions in the 1980s but have been gradually more specialized since the late 1990s. The geographical patterns of Chinese manufacturing industries significantly vary by industry. Statistical results show that significant locational determinants of Chinese manufacturing industries include industrial policies, labor quality and cost, scale economies, natural resources and market accessibility. The significance of locational determinants also depends on the nature of industries. The empirical results would provide scientific supports for regional industrial policies.
