In 2014,Intergovernmental Panel on climate change(IPCC) released the fifth assessment report points show that global warming is very likely(95%) is caused by human activities, the greenhouse gas emissions caused by the burning of fossil fuels has reached an unprecedented level, which has brought adverse effects to the production of human life. By 2015, climate conference held in Paris, global 195 parties countries of the United Nations Framework Convention on climate change through the historic global climate change agreement, the commitment of the parties to the independent contribution "to participate in the global response to climate change action. China as a responsible developing country, also made an independent commitment to emission reduction,which is 2030 unit GDP carbon dioxide emissions dropped 60% to 65% than 2005 and non fossil energy accounts for the proportion of primary energy consumption reached about 20%. At the same time, in 2016,the thirteen five year plan proposed to further promote energy revolution, efforts to promote energy production and use patterns change, optimize the structure of energy supply, improve energy efficiency, building low-carbon clean, safe and efficient modern energy system, namely to carry out the development of the concept of" innovation, coordination, green, open sharing" to achieve sustainable development of energy, economy and environment.Based on the above-mentioned background, this paper uses the ridge regression analysis and vector autoregressive model to study the carbon emission reduction effect of the energy industry investment in fixed assets, to provide a theoretical basis for promoting the energy supply side reforms and establishing modern energy system to. The results showed that: energy fixed assets investment through the economic aggregate, energy structure, energy efficiency of three ways to affect carbon dioxide emissions, but exist a certain block. In addition, the carbon emissions and economic growth of the relative variable carbon intensity, further study the relationship between fixed assets investment and carbon intensity in different energy industry. The results showed that the coal mining industry investment in fixed assets increase will promote carbon intensity increased, that is not conducive to carbon dioxide emission reduction; the other three industry investment fixed assets increased will significantly reduce carbon intensity, that will promote the increase of carbon dioxide emission reduction and economic benefits. In addition,from a long-term point view, in addition to the coal mining industry, carbon intensity reductions will result in a significant increase in the energy investment in fixed assets and economic benefits, namely carbon emission reduction policies have stimulative effect to investment increase and economic development. Thus give advice to strictly control the coal industry investment, strengthen the use of clean and efficient coal development; steady development of oil production, vigorously develop the natural gas, increase oil and natural gas proportion; vigorously develop renewable energy, and gradually replace fossil energy. |
