[0014] Figure 1This is a structural schematic diagram of a carbon market efficiency evaluation method considering multi-dimensional perspectives according to the present invention. DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] Embodiment 1, Figure 1 The present invention provides a carbon market efficiency evaluation method considering multi-dimensional perspectives, comprising the following steps: S1, obtain the enterprises participating in carbon credit trading in the tested area, and obtain carbon market efficiency impact data based on the enterprises.
[0017] Carbon credit impact index refers to the price paid for emitting one unit of greenhouse gases such as carbon dioxide under the carbon trading or carbon pricing mechanism. It reflects the external cost of carbon emissions to the environment and society and is an important economic signal to encourage companies and individuals to reduce carbon emissions. By observing the carbon credit impact index, policymakers can encourage investment in low-carbon technologies and the use of renewable energy, thereby promoting greenhouse gas emissions reduction and supporting sustainable development goals.
[0018] The specific steps for obtaining the carbon credit impact index are as follows: Obtain the historical supply and demand data of carbon credits in the area to be tested, remove abnormal fluctuation data in the historical supply and demand data of carbon credits, and use the moving average method to obtain the average value of supply and demand; Obtaining historical carbon credit demand in the area to be tested, and calculating carbon credit demand elasticity through linear regression analysis method based on the historical carbon credit demand; Obtaining the historical supply of carbon credits in the region to be tested, and obtaining the supply elasticity through a regression analysis method based on the historical supply; According to the supply and demand data, the average value of the supply and demand is obtained by the moving average method, the average value of the supply and demand is used as a threshold, and the external influencing factor is obtained by calculating based on the supply, demand and the threshold of the supply and demand based on a preset external influencing factor formula; The carbon credit impact index is calculated based on a preset carbon credit impact index formula according to the carbon credit demand, carbon credit supply, external influencing factors, carbon credit demand elasticity and carbon credit supply elasticity to obtain a carbon credit impact index.
[0019] The specific calculation formula of the carbon credit impact index is as follows:
[0020] The specific calculation formula of the external influencing factor is as follows:
[0021] In the formula, is the Carbon Credit Impact Index, is the cost of the carbon credit demand curve, which depends on the quantity demanded and the elasticity of demand, is the cost of the carbon credit supply curve, which depends on the quantity supplied and the supply elasticity, is an external influencing factor, is the carbon credit demand, is the carbon credit supply, is the carbon credit demand elasticity, is the carbon credit supply elasticity, is the flat threshold of carbon credit supply, is the threshold for carbon credit demand.
[0022] It should be noted that the costs of demand and supply depend not only on quantity, but also on elasticity. Higher elasticity means that price changes have a greater impact on demand or supply. External influencing factors reflect possible influences in the market, including but not limited to carbon tax policies, fluctuations in the international carbon trading market, and advances in environmental protection technologies. The denominator introduces the difference between demand and supply and takes into account the impact of elasticity, which makes changes in carbon prices more flexible and dynamic.
[0023] Further, the advantages of analyzing the price elasticity of demand and the price elasticity of supply on the carbon credit impact index are as follows: By comprehensively considering the elasticity of demand and supply, the carbon price can better reflect the real dynamics of the market, enhancing the applicability and accuracy of the model. Secondly, the introduction of external factors enables the model to accurately capture the impact of technological progress on the market and improve its adaptability to changes in the market environment. By considering the differences in demand and supply, it allows for in-depth analysis of the price formation mechanism, which helps policymakers evaluate the effectiveness of different policy tools. The complex formula provides a more comprehensive perspective for academic research and practical applications, supports the goals of sustainable development and low-carbon economic transformation, and promotes a deep understanding and predictive ability of the carbon market.
[0024] Emission reduction adjustment factor, the emission reduction adjustment factor refers to the amount of greenhouse gas emissions reduced through various measures and policies. In environmental science and climate policy, the emission reduction adjustment factor is often used to evaluate the effectiveness of emission reduction measures and the impact of environmental policies. Specifically, the emission reduction adjustment factor is calculated by comparing baseline emissions with actual emissions.
[0025] The specific steps for obtaining the emission reduction adjustment coefficient are as follows: Obtain historical emission data of the area to be tested, identify and remove outliers and erroneous data in the data, and sum up the historical emission data to calculate the average carbon emissions, and use the average carbon emissions as the benchmark emissions; Obtain carbon emission data for a period of time before and after the introduction of the emission reduction technology, and calculate based on the carbon emission data for a period of time before and after the introduction of the emission reduction technology to obtain the emission reduction ratio after the introduction of the emission reduction technology; The adjusted emissions are calculated based on the baseline emissions and the emission reduction ratio caused by technological progress based on a preset adjusted emissions formula to obtain the adjusted emissions; Obtain historical carbon emission data in the area to be tested, and capture time dependencies and complex patterns through time series models to determine the impact of time factors; The emission reduction adjustment coefficient is calculated based on a preset emission reduction adjustment coefficient formula according to the baseline emission amount, actual emission amount and the influence of time factors to obtain the emission reduction adjustment coefficient.
[0026] The specific calculation formula of the emission reduction adjustment coefficient is as follows:
[0027] The specific calculation formula for the actual emissions is as follows:
[0028] In the formula, is the emission reduction adjustment factor, is the baseline emission, is the actual emission, It is the influence of time factor. It is the emission reduction effect caused by technological progress.
[0029] It should be noted that the calculation of the emission reduction adjustment coefficient not only takes into account static emission differences, but also reflects dynamic technological development factors, thereby providing policymakers with more accurate decision-making basis. This complex calculation method helps to more comprehensively understand and evaluate the effectiveness of emission reduction measures.
[0030] Furthermore, the advantages of obtaining the emission reduction adjustment coefficient by introducing the emission reduction effects caused by policy factors, the emission reduction effects caused by technological progress, and the emission reduction effects caused by economic factors are analyzed as follows: The introduction of technical factors can more accurately capture the impact of different driving factors on emission reduction, including the fact that technological progress effectively reduces the carbon footprint of production and consumption. This comprehensive analysis reveals complex causal relationships, allowing the model to more accurately reflect the actual situation and provide decision-making support; The consideration of time factors effectively captures the lag in the effects of policy implementation and technological progress on emission reduction. Through dynamic modeling, the changing trends of emissions at different time points can be identified, making the model more flexible and adaptable to the changing environment. Such flexibility not only enables the model to respond to short-term emergencies, but also effectively supports long-term emission reduction strategies and planning. The dynamic nature of the model allows it to be used not only for short-term assessments, but also to provide support for long-term environmental planning and emission reduction target setting, helping to achieve sustainable development goals. The implementation of this model requires the collection and analysis of relevant data, thereby promoting data-driven decision-making processes and improving the scientific nature of decision-making.
[0031] Price volatility status, price volatility status is an important indicator to measure the degree of price change, which is used to analyze market risks and uncertainties. In the financial field, price volatility status refers to the fluctuation range of prices within a specific time period, reflecting the instability of market prices.
[0032] The specific steps for obtaining the price fluctuation status are as follows: Obtain historical carbon price data for the area to be tested, process the acquired carbon price data, and remove outliers and missing values; Calculating according to the carbon price data to obtain an average carbon price; Setting the carbon price data to a plurality of observation points, and obtaining the carbon price data at each observation point; The price fluctuation state is obtained by calculating the carbon price data of each observation point and the average value of the carbon price based on a preset price fluctuation state formula.
[0033] The specific calculation formula for the price fluctuation state is as follows:
[0034] In the formula, is the price fluctuation state, is the total number of observed time points, is the carbon price at the i-th time point, is the average carbon price.
[0035] S2, constructing a carbon market stability assessment model based on the carbon market efficiency impact data and a machine learning algorithm to obtain the carbon market stability status.
[0036] In this embodiment, the carbon market stability assessment model is constructed based on the machine learning algorithm according to the carbon market efficiency impact data to obtain the carbon market stability status, specifically: According to the carbon credit impact index, emission reduction adjustment coefficient, price fluctuation status and policy transparency, a carbon market stability assessment model is constructed based on a machine learning algorithm to obtain the carbon market stability status.
[0037] The specific calculation formula of the carbon market stability assessment model is as follows:
[0038] In the formula, is the stability of the carbon market, is the Carbon Credit Impact Index, is the emission reduction adjustment factor, It is a price fluctuation state.
[0039] It should be noted that if the carbon market stability value is greater than 1, it means that the carbon market is relatively stable; if the carbon market stability is less than 1, the carbon market faces the risk of instability; the higher the price volatility, the more unstable the market, so the price volatility has a negative impact on stability; the carbon credit impact index and policy transparency are proportional to the stability of the carbon market. The higher the carbon credit impact index and policy transparency, the more stable the market. By monitoring these four parameters, market participants regularly evaluate the stability of the carbon market and adjust their strategies to cope with sudden market changes.
[0040] Furthermore, the advantages of the carbon market stability model are analyzed from four aspects: carbon credit impact index, emission reduction adjustment coefficient, price fluctuation status and policy transparency. The specific advantages are as follows: By multiplying the carbon credit transaction price with the emission reduction adjustment coefficient, the carbon market stability model formula directly reflects the combination of market economic incentives and environmental benefits. High carbon credit impact index and emission reduction adjustment coefficient values indicate that the market has strong economic incentives for emission reduction, which helps to promote the enthusiasm of market participants and thus enhance market stability. Taking policy transparency into consideration, the impact of transparent policies on market confidence is emphasized. Higher transparency enables market participants to better predict future policy changes, reduce market shocks caused by policy uncertainty, and improve market stability. The carbon market stability model is flexible and can adjust parameters according to the specific conditions of different regions and markets. It is applicable to a variety of market environments and provides a basis for related market analysis and research.
[0041] S3, obtaining the carbon market efficiency according to the carbon market stability state.
[0042] In this embodiment, the carbon market efficiency is obtained according to the carbon market stability state, specifically: If the carbon market stability value is greater than 1, a stability signal is issued; If the carbon market stability value is less than 1, a danger signal is issued.
