At present, the stress should be laid on tertiary sectors like finance, foreign trade, commerce, real estate, far-ocean transport, post and telecommunication, information and travelling service and so on. In the secondary industry, export processing and high and new technological industries should be put first, while the original raw-material industry should be improved in processing depth.

The potential benefits of utilizing crowdsourcing in product design are well-documented, but little research exists on what are the barriers and opportunities in adopting crowdsourcing in new product development (NPD) of manufacturing SMEs. In order to answer the above questions, a Proof of Market study is carried out on crowdsourcing-based product design under an Innovate UK funded Smart project, which aims at identifying the needs, challenges and future development opportunities associated with adopting crowdsourcing strategies for NPD. The research findings from this study are reported here and can be used to guide future development of crowdsourcing-based collaborative design methods and tools and provide some practical references for industry to adopt this new and emerging collaborative design method in their business.展开更多

Principal component analysis is used to delineate spatial patterns. The analyses show that prior to the reform China's spatial development pattern was characterized by the dominance of the three municipalities and the Northeast, as well as by both the coast-interior and the north-south disparities. Northern provinces were generally more industrialized and economically powerful than the southern ones. After two decades of reform, regional development has become multi-centered with South China, the Yangtze Delta and the Beijing-Tianjin area being the three most important regions of the country. The coastal provinces as a whole rose to prominence on China's economic map while the Northeast has diminished its clout. The coast-interior gap not only remains but may have widened. The north-south disparity also still exists but there has been a role reversal with the south now in the lead position. Virtually all inland provinces now find themselves at or near the low end of the development spectrum. We argue that the major reason for the recent shifts in Chinese space economy is the spatially differentiated economic growth resulted from the reform and open door policy and from the new, uneven development strategy adopted by the Chinese government. The paper discusses four specific factors that have reshaped China's spatial development patterns.展开更多

It is a non-profit institute. Those scientists who really dedicate themselves to science and loving science more than anything else can become its member. In the friendly door-opened Institute, they can maximize their time and energy to engage in their scientific creativity. They have also believed that science would be more truthful and wonderful if scientists do not have to spend a lot of time on funding application, and that great scientific findings and creations in history were often made by those who were least supported or funded but driven by interesting imagination and curiosity. Recollected in this review article is its establishing and developing processes, as well as its philosophy and accomplishments. Particularly, its productive and by-productive outcomes have covered the following five very hot topics in bioinformatics and drug development: 1) PseAAC and PseKNC;2) Disported key theory;3) Wenxiang diagram;4) Multi-label system prediction;5) 5-steps rule.

Two measures of financial development were used: broad money and domestic credit to the private sector, each as a ratio of gross domestic product (GDP). In this regard, two models were developed for each indicator. The Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) tests were used to determine stationarity of all the variables. Furthermore, Johansen test was employed to ascertain possible cointegration among variables. The vector error correction model (VECM) was employed to examine the short-run and long-run dynamics among the variables in each model. The results indicate that the relationship among financial development, trade openness, and economic growth is sensitive to the financial development indicator chosen.展开更多

With its long-standing cultural heritage and forward-looking development vision, Shanghai has created a lot of cultural and creative parks. At present, these industrial clusters have begun to take shape, forming a certain concentration of creative design. In this investigation, we focused on the investigation of the creative industrial park in the Pudong New Area. We found several typical cases of good development in Beijing, Hangzhou and other old districts in Pudong New Area. Through these successful and typical investigations, we will gain effective experience in property fights protection, institutional design, government supervision, service enhancement, etc., in addition to providing advice on intellectual property rights for the three-in-one bureaus that are exploring ways of working, and also related to The management department provided suggestions from other relevant parties and worked together to contribute to the creation of the Shanghai "International Creative Industry Center" program.展开更多
