"Without an appropriate research setting, a study cannot be qualified as a reasonable piece", this notion is manifested in the methodological polices. In this research, we attempt to examine previous studies within the scope of technology evolution and market perception in telecommunication industry through extracting research structures, methodologies, corresponding variables, and processing methods. A general process of social scientific research is adopted to analyze eighty-four selected papers; and simultaneously, the framework for doing this analysis is established, as well. In this manner, we inspect the subjects and the issues in these papers according to product types, academic domains, and divisions of technological evolution (from 1G to 4G). Then, their research designs are anatomized into the key dimensions of general research conventions. This research eventually provides an entire picture of a research scenario for mobile telecommunication industry; and apparently, this framework can help scholars to establish specific tendencies for academic scenarios in future research plans. Also, we propose the main streams and emerging issues can be expected to engage in the future within both the academic and the operational fi elds. 展开更多

This article explores the effects of investment upon energy intensity by applying a unique panel data of China's 27 provinces between 2004 and 2013.In addition,it also particularly stuthes other factors,such as energy price,economic structure,and urbanization.The results,based on four econometric regression model results,suggest that in general,the indigenous investment on research and development is a more powerful tool to decrease China's energy intensity regardless of region disparity.The foreign direct investment(FDI) has a prominent but not persistent effect on energy intensity.However,the outward direct investment has not shown its significant impact on energy intensity.At the level of an aggregate economy and China's eastern region,the results demonstrate that FDI improves energy efficiency significantly.For the central and western provinces,FDI does not support the similar conclusion.Based on these analyses,we present the corresponding regional policies for policymakers. 展开更多

Background:Though many countries,including China,are moving towards malaria elimination,malaria remains a major global health threat.Due to the spread of antimalarial drug resistance and the need for innovative medical products during the elimination phase,further research and development(R&D)of innovative tools in both epidemic and elimination areas is needed.This study aims to identify the trends and gaps in malaria R&D in China,and aims to offer suggestions on how China can be more effectively involved in global malaria R&D.Methods:Quantitative analysis was carried out by collecting data on Chinese malaria-related research programmes between 1985 and 2014,invention patents in China from 1985 to 2014,and articles published by Chinese researchers in PubMed and Chinese databases from 2005 to 2014.All data were screened and extracted for numerical analysis and were categorized into basic sciences,drug/drug resistance,immunology/vaccines,or diagnostics/detection for chronological and subgroup comparisons.Results:The number of malaria R&D activities have shown a trend of increase during the past 30 years,however these activities have fluctuated within the past few years.During the past 10 years,R&D on drug/drug resistance accounted for the highest percentages of research programmes(32.4%),articles(55.0%in PubMed and 50.6%in Chinese databases)and patents(45.5%).However,these R&D activities were mainly related to artemisinin.R&D on immunology/vaccines has been a continuous interest for China’s public entities,but the focus remains on basic science.R&D in the area of high-efficiency diagnostics has been rarely seen or reported in China.Conclusions:China has long been devoted to malaria R&D in multiple areas,including drugs,drug resistance,immunology and vaccines.R&D on diagnostics has received significantly less attention,however,it should also be an area where China can make a contribution.More focus on malaria R&D is needed,especially in the area of diagnostics,if China would like to contribute in a more significant way to global malaria control and elimination. 展开更多

The goal of this study is to measure the effectiveness of a career development system implemented at a research and technology organization at satisfying the context requirements of a decree issued by the Basque Country government.Through in-depth surveying of 80 R&D professionals over the five years,the authors aimed to determine whether a career development system,when it is linked to context requirements and researchers’contributions,could offer researchers feedback about their career aims and increase their job satisfaction.During the five years of the study,the researchers’capacity to meet career requirements improved by 20%,and job satisfaction,although it declined at first,increased substantially in the last two years,reaching a historic high for the employee satisfaction survey. 展开更多

Researching China's innovative economic and financial innovation issues under the background of the New Normal, we need to carefully analyze the internal structure and interaction of China's macroeconomics.The computable general equilibrium(CGE) model has outstanding advantages on predicting the external shock influences on economic system, but previous studies on forecast for China's future economy mostly considered a high growth rate which is hard to comply with the New Normal scene. By constructing China's macroeconomic dynamic CGE(DCGE) model and anticipating the economic impact of the New Normal, this paper finds that the New Normal has a certain extent inhibition on China's macro-economy and innovation. However, after adding the research and development(R&D) subsidy policy, the negative impacts of the New Normal on macro-economy can be eliminated to realize the optimization of economic structure. In addition, after combining the financial innovation promoting policy and the Ke Qiang index through the simulation of macro-economy, we find that the quality of economic growth is improved. Finally, we provide the policy recommendations for the realization of an innovative economy under China's New Normal. 展开更多

In this paper, we study the location distribution and determinants for Chinese firms’ overseas Research and Development(R&D) activities, based on a dataset of 1,500 Chinese firms that established overseas R&D subsidiaries during the years 2010-2014. Integrating Dunning’s eclectic paradigm and Uppsala Model, we construct a two-dimensional model, which consists of the determinants from host countries and from the interactions between the host countries and the home country, China. We use a multiple-regression method to analyze the determinants and rationale of the location choice of Chinese firms’ overseas R&D activities. By identifying the determinants of the location of the Chinese firms, we aim to reveal whether and where the location strategy of Chinese firms’ R&D globalization differs from those of the firms in the U.S., Europe and Japan;and to provide a reference for Chinese firms in their strategy-making on R&D globalization. 展开更多
