Open source software (OSS) movement, which is a particular phenomenon in the software industries, seems to be a challenging opportunity for the developing countries that wants to move their own software industries up the value chain. This paper, using China as an example, identifies the issues that need to be addressed for the software industry, as well as the special characteristics of software products that need to be dealt with carefully. It proposes promoting OSS as a strategy the Chinese government should adopt to grow the software industry and the specific actions that should be taken.展开更多

This paper uses the Revealed Comparative Advantage (RCA) index, Export Similarity index and Gray Model to analyze the competitiveness and complementarities of the software industry between China and India. The results show weak competitiveness of China and India’s software products in the main export markets; therefore it will be enhanced in the long-term. The software industries of the two countries are highly complementary. Therefore, China and India should strengthen cooperation in this industry to seek more benefi ts.展开更多

[Method] Based on long-term energy alternative planning system software （LEAP）, ＂LEAP of China＇s cement industry＂ model was established to simulate energy conservation and emission reduction in China＇s cement industry from 2010 to 2040 in different technologic situations. E ResultJ To save ener- gy and reduce CO2 emissions, new dry process kiln has priority over other technologies or measures, followed by equipment enlargement, mechani- cal shaft kiln, power generation system based on waste heat, as well as high-efficiency and energy-saving grinding technology, and new prepara- tion technology. If all the advanced technologies and measures are adopted, energy consumption and C02 emissions can be reduced by about 40.76% and 42.97% respectively. [ Condusion] LEAP of model is suitable for analyzing energy saving and emission reducing in China＇s cement industry and other industrial fields.展开更多

A conceptual framework was generated to guide the investigation. Data were elicited using a detailed questionnaire which generated 53 usable responses; follow-up interviews with 17 of the 53 respondents; and four interviews with relevant government officials （civil servants from the Ministry of Science and Technology and state-owned banks）. There were three main fmdings. Chinese software SMEs tend to be reluctant to adopt new technologies from local tmiversities; there is a lack of common purpose between the parties; and entrepreneurs who did undertake such technology transfer felt the process was badly impeded by the lack of available finance, and expressed fears about poor protection of intellectual property rights in China. The majority of the sample firms acted opportunistically, taking advantage of the benefits offered under government schemes to earn rapid returns mainly using extant technologies. These conclusions suggest that the Chinese government＇s policies in this area of technology transfer have had only limited success.展开更多
