On the basis of a rich panel data set of large- and medium-sized Chinese manufacturing enterprises, we observe that different types of firms (i.e., state-owned enterprises [SOEs], foreign-funded ownership [FFO] of firms, Hong Kong-Macau-Taiwanese [HMT] companies and privately-owned firms) exploit different stages of the innovation – productivity chain depending on the extent of market concentration. By applying a modified CDM model, this study reveals that SOEs tend to be more active in making innovative decisions and pursuing innovative investments but are less efficient in terms of innovation output and labour productivity, whereas FFO firms have relatively high labour productivity but are less active in the first three stages of the innovation – productivity chain. Market competition favours SOEs in the production of additional innovation products. Foreign firms are efficient in labour productivity if they are operating in a concentrated market. By using the metaphor of DNA, this study explains the heterogeneity among these different forms of ownership and generates several managerial implications.

This study examines how competitive and cooperative relationships within R&D consortia influence member firms’ innovation output. We propose a U-shaped relationship between the presence of market competitors for a member firm and the firm's joint R&D output with other consortium members, and examine how the relationship is mediated by interactions with other members at the firm level and moderated by collaborative efforts at the consortium level. Using a unique sample of 320 firms from 52 R&D consortia in China, we find support for our predictions. This multi-level study extends our understanding of competition and cooperation in multi-party networks and provides insights for creating a balance between the two forces that is conducive to innovation.

Motivational characteristics are influential in shaping adolescents' desire to persist in sport or to discontinue their sport participation. Self-determination theory (Deci & Ryan, 2000) was utilized as the theoretical framework for this study. This theory examines whether sustained participatory involvement, defined as continued participation in the sport through the next year, was influenced by individuals' self-determined motivation and by the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness. Four hundred ninety two soccer players between the ages of 13 and 17 years comprised the sample. Results indicated sport dropout was explained by higher levels of amotivation, external regulation, and introjected regulation and by lower satisfaction of relatedness and autonomy needs. The findings of this study contribute to the knowledge base on sport dropout as they supported many of self-determination theory.

In line with self-determination theory (SDT: Deci & Ryan, 1985, 2002) the satisfaction of the basic psychological needs for autonomy, competence, and relatedness has been identified as an important predictor of behavior and optimal functioning in various contexts including exercise. The lack of a valid and reliable instrument to assess the extent to which these needs are fulfilled among Portuguese exercise participants limits the evaluation of causal links proposed by SDT in the Portuguese exercise context. The aim of the present study was to translate into Portuguese and validate the Basic Psychological Needs in Exercise Scale (BPNES: Vlachopoulos & Michailidou, 2006). Using data from 522 exercise participants the findings provided evidence of strong internal consistency of the translated BPNES subscales while confirmatory factor analysis supported a good fit of the correlated 3-factor model to the data. The present findings support the use of the translated into Portuguese BPNES to assess the extent of basic psychological need fulfilment among Portuguese exercise participants.

China's rapid growth and increased integration with the global economy over the past three decades have significant economic impacts and political implications for Latin America. This paper reviews the debate over whether these impacts have on balance been positive or negative for the region. It argues that those who emphasise the positive economic impacts of China have been over-optimistic and underplay some of the negative impacts associated with Chinese competition in manufacturing and increasing Latin American specialisation in primary products. On the other hand, when focusing on the political dimensions, there has been a tendency to exaggerate both the extent of China's influence in the region and the fears to which this gives rise, particularly among US commentators.
