Abstract
In this paper, we establish an economy-energy-environment integrated model by introducing a new technical mechanism, that is, the revised logistic model, to be the technical core of the energy module. This gives the conventional top-down modes more bottom-up features and allows us to model the evolutionary pathways of multiple non-carbon technologies. The model’s simulations indicate that the mixed policy of both carbon tax and subsidy plays a significant part in promoting the development of new energy technologies. The shares in total primary energy usage for PV solar, geothermal power and wind energy, for example, will have increased to 24.9, 9.7 and 6.12 %, respectively. Meanwhile, technological progress can be significantly enhanced by introducing research and development (R&D) investment. As a result, the percentages of usage of the above three technologies are likely to increase to 26.2, 12.1 and 7.2 %, respectively, in that case. Besides, energy supply market will be locked up by non-fossil energy as early as 2035, or thereabouts, under the current R&D investment regime. Thus, the expansion of R&D may significantly improve the carbon-reducing potential of the mixed policy and perform well in easing the tax burden on businesses and consumers in the long run.

Notes
Gerlagh and van der Zwaan [9] give sensitivity analysis of substitution elasticities between fossil fuels and zero-carbon energy based on their DEMETER model. When the value of elasticity is set to be 2.0, 3.0 and 4.0 respectively, the carbon emissions in 2020 will range from 7.6 to 7.8 GtC, and the reductions will be in the interval 36–73 %; shares of non-fossil energy demand will change from 9 to 16 %.
Top-down models focus on macroeconomy, in which output is given by a production function, with capital, labour to be the inputs. Sometimes, energy or electricity is also input to be the complemented production factor, leaving energy technology advancement exogenized by automatic energy efficiency improvement (AEEI). Bottom-up models always get relatively rich set of specific energy technologies, making technological progress an exogenous process of cost and efficiency improvements. That is why the bottom-up models are often called “energy-system model” [8, 36].
Rubin et al. [39] did much research on the learning rates of multiple energy technologies, suggesting that the costs of the technologies are declining in the past few decades, with learning rates ranging from 10 to 12 %.
In the one-dimension case, the relationship between parameter χ and the standard deviation can be described as χ 2 = π 2/3σ 2 ≈ 1.81π 2/σ 2, when turning to the multi-dimension case, the relationship becomes more complex [2]. Overall, the dynamics of logistic curve is sensitive to the parameter value χ, for the formulation, S t = αS t − 1(1 − S t − 1), if α ≥ 3.57, the long run solution starts to become chaotic; if α ≥ 3.83, there will be unaccountable number of asymptotically α-periodic trajectories, as well as cycles for every integer period [26].

Data for R&D are only available for IEA countries (http://www. iea.org/stats/index.asp), data for the rest of world is not given in detail. Then we adopt the estimation of total public R&D expenditures for the entire world in 2000, and the share the R&D relates to energy is set to be 2 %, referring to Popp [36].
The CO2 emission in this model in 2100 is much lower than in the RICE model (38 GtC) while approaches to the projection in the DICE model (21 GtC), but the carbon projections in both E3METL and DICE model are in the IPCC’s projection interval of 5 to 35 GtC [33, 42]. The comparisons of the main results in this work to that of the existing models are listed in Table 4 in Appendix 1.
The results here are in line with that of most of the relevant studies; for example, Gerlagh and van der Zwaan [10] believed that at least half of the world’s energy supply would be provided by alternative technologies at the end of the century.

The “lock-up” points define the first time when the share of non-carbon technologies surpasses that of fossil fuels.
