This paper seeks to analyze the relationship between China and the Northeast region of Brazil, aiming to identify how the renewable energy sector is being developed.

The authors analyzed secondary data from the official databases from China-Brazil chambers of commerce to establish the main points related to renewable energy in Brazil's Northeast.

It is possible to notice the main investments, highlighting the wind energy as a more prominent source recently. The authors also point the huge influence from China on Brazil's Northeast energy sector.

It is difficult to identify the amount of Chinese capital due to the large number of mergers and acquisitions that has been taking place in recent years.

Identification of regions that have been receiving investments and the main interests of Chinese investors in the renewable energy sector.

Demonstration of how the renewable energy sector has taken an important turn in Brazil due to Chinese investment.

To evaluate a regional consortium, analyzing its strategies for partnerships with China to help each other in global questions, as is the case of renewable energy.

This paper aims to systematize the contextual factors that influence the intention to use citizens and governments-initiated platforms, presenting them as non-functional requirements (NFRs), to facilitate their understanding to implementers.

A systematic mapping of the literature was done to identify the contextual factors from citizens and governments (C2G) adoption, followed by a survey applied to 938 potential users of this type of technology. The results were analyzed through logistic regression to understand the impact of the contextual factors on the intention to use C2G platforms and then those contextual factors were formalized as NFRs represented by a Softgoal Interdependence Graph.

Among the results, the most prominent factors were the influence of the “users perceived contribution” and the “citizens concern about the city conditions”. Finally, some strategies are suggested to help public managers and developers to optimize the factors that have shown to be significant.

This study can support e-gov policies in the implementation of C2G platforms because several municipalities need assistance in taking actions to foster greater citizens’ engagement. An example of this type of contribution is the indication of the factors of greatest impact in the adoption of use and the indication of paths to be followed if the manager and developers decide to focus on each of them.

The identification of several contextual factors which influence C2G platforms adoption and their systematization with the purpose of jointly visualizing and evaluating them.
