| Summary/Abstract |
The renewable portfolio standard (RPS) in China is to put into effect at the beginning of 2020, which will inevitably affect the strategy of stakeholders in retail electricity market. To study the effect of RPS on retail electricity market, we take the regulators (energy regulatory authorities) and two types of power sales companies with heterogeneous strength into consideration. Then a system dynamics model of tripartite evolutionary game is developed to analyze the strategy interaction of stakeholders and simulate the corresponding evolution process. Based on the background of Chinese renewable power industry, the scenario analysis method is employed to investigate the impacts of key parameters in relation with RPS scheme on stakeholders’ strategy selections. The results show that, to basically ensure all the power sales companies comply with quota obligation, TGC price of different stages should maintain at desired levels, net profit of renewable power sales should be no less than that of conventional power sales, and incentive and punishment should be within a reasonable range. In particular, the results reveal some policy effects such as reversal effect, blocking effect and over-reliance effect. More importantly, these results provide some policy recommendations for the rapid development of renewable power industry.

| Summary/Abstract |
The implementation of renewable portfolio standards (RPS) in China is limited by the interests of the sector being regulated. Power companies generally lack the incentive to generate renewable power. They can be expected to resist the implementation of RPS standards, which will in turn affect the successful implementation of the RPS policy. Thus studying the strategic interaction and co-evolution between the government and power companies under the RPS regulation is of great importance.

| Summary/Abstract |
Prefabrication construction method has been considered an effective way for enhancing the environmental performance and sustainable development of the construction industry. Many countries have imposed policies to stimulate the implementation of prefabrication. However, the efficiency of the incentive policies in China did not turn out as expected because of the existing benefit game between real estate enterprises and the government under the influence of consumers' purchasing intention. An evolutionary game model was established on the basis of 16 variables influencing the strategy selection of game players for determining the effective incentive policies. The interaction effect of the two players’ behaviours was discussed. Four probable scenarios of evolutionary stable strategy (ESS) exist in the game. However, the probabilities of “Incentive” from the government and “Implement” from real estate enterprises depend on the values of the 16 variables. The simulation of the evolutionary system was conducted to analyze the critical variables influencing the game. The increase of reputational incentives, financial incentives, the acceptance level of consumers and penalty and the reduction of additional costs can speed up the achievement of ESS between the government and real estate enterprises. Incentive policies should focus not only on real estate enterprises but also on consumers, manufacturers of prefabricated components and contractors.

| Summary/Abstract |
In countries highly dependent on coal and oil, the substitution of relatively cleaner energy for fossil fuels in industrial and residential sectors (cleaner energy substitution, or CES) is conducive to technology advancement and pollution abatement. Since CES is a process met with resistance by a portion of enterprises in China, this study will investigate the roles of external factors by simulating CES diffusion in enterprise networks. The PEST (political, economic, social, and technological factors) analysis framework, referencing corporation strategy management, is employed to select potential external factors of CES diffusion. The results show that factors will affect the diffusion of CES by changing the payoffs of different enterprises. Reducing the costs of cleaner energy and related equipment will promote diffusion. Besides, improving consumer preferences for green products, consolidating responses to public complaints on pollution and promoting information exchange among enterprises are beneficial to diffusion. It is novel that this paper demonstrates that diffusion will be hindered by supply interruptions of cleaner energy, which means that stable supply after a wide range of adoption is important. Focusing on PEST factors, this study introduces a useful framework to investigate the potential factors of enterprises’ green decisions and behaviours and offers fresh insights into promoting CES adoption and energy transition in developing countries.
