Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, to the technical side of the embodiment of the present invention
Case is clearly and completely described.Obviously, described embodiment is the part of the embodiment rather than whole of the present invention
Embodiment.Based on described the embodiment of the present invention, those of ordinary skill in the art's all other embodiments obtained, all
Belong to the scope of protection of the invention.
Embodiment 1：In the following, it is further illustrated the present invention by taking Henan Province as an example.
Estimate the conspicuousness of Henan Province's energy-consuming effect on environment, structure considers Henan Province's energy efficiency of Environmental costs
Calculating model, Henan Province's energy efficiency under analysis environments constraint.
(1) impact analysis of Henan Province's energy-consuming to environment.Energy-consuming passes through along with a degree of pollution
Quantitative analysis carrys out the degree of quantitative study energy-consuming effect on environment, and setting multivariate regression models is as follows：
Wherein, pollution refers to environmental pollution, will use the discharge of ammonia nitrogen compound, two in waste water COD discharge capacity, waste water respectively
Sulfur oxide emissions amount, nitrogen oxide emission and cigarette (powder) dirt discharge capacity are weighed；EC is energy consumption, is that core becomes
Amount；Pcgdp refers to GDP per capita.Fdi is direct foreign investments；ε is Disturbance.The energy based on 18 prefecture-level cities of Henan Province,
Environmental data carries out simulation measuring and calculating, the results detailed in Table 1 to the environment influence of Henan Province's energy-consuming.
Influence of 1 energy-consuming of table to environment
Note：1. it is t values in bracket.
2. * is represented in 10% level significantly, * * represent that in 5% level significantly, * * * are represented in 1% level significantly.
From Regression Analysis Result as can be seen that Henan Province often consumes 1,000,000 tons of standard coals, waste water COD discharge capacity can be generated
0.362 ten thousand tons, 0.040 ten thousand tons of ammonia nitrogen compound discharge capacity in waste water generates 0.710 ten thousand tons of SO2 emissions, generates nitrogen oxygen
0.509 ten thousand tons of compound discharge capacity, cigarette (powder) dirt discharge capacity can increase by 0.833 ten thousand tons.It can be seen that Henan Province's energy-consuming is to ring
The influence highly significant in border.
(2) the energy efficiency assessment under environmental constraints.When estimating energy efficiency, chemical oxygen demand in waste water is considered as a whole
The pollutant emissions indexs such as object discharge capacity, SO 2 in waste gas discharge capacity and the measurement of cigarette (powder) dirt discharge capacity, as non-
Desirable output is included in input-output analysis frame.
It is assumed that constant returns to scale, using each provinces and regions as decision package (DMU), each provinces and regions capital invested (K), labour
(L) and the energy (E).Output is divided into two classes, and one kind is desirable output, and (Y) is weighed with each province's regional GDP；Another right and wrong
Desirable output is weighed respectively with chemical oxygen demand object discharge capacity, SO 2 in waste gas discharge capacity and cigarette (powder) dirt discharge capacity in waste water
It measures (being represented with vectorial B).With some provinces and regions DUMkFor, the planning type of the non-desirable output rear direction distance function model of introducing
For：
maxβ
s.t.
X·λ+β·gx≤xk
Y·λ+β·gy≥yk
β·λ+β·gb=bk

Wherein, xkIt is DUMkVector input, ykIt is DUMkDesirable output vector, bkIt is DUMkNon- desirable output to
Amount.gx、gyAnd gbIt is direction vector, features the situation that input, desirable output and non-desirable output change respectively, β is to invalid
Rate is estimated, but it is influenced by direction vector length, after non-desirable output is introduced, further by direction distance function efficiency
Value is modified to：
θkIt is used directly for measure of efficiency.Wherein, wi IState the flexible strategy to i-th kind of input, wr GFor the desirable output of r kinds
Flexible strategy, wt BFlexible strategy for the non-desirable output of t kinds.The effect of above-mentioned flexible strategy is to embody the significance level of different indexs, can
Construct weight matrix
After considering environmental constraints, in Index Weights each to input and output, weight matrix is set as (1/9,1/9,1/9,
1/3,1/9,1/9,1/9) it, is meant that various inputs, desirable output and the non-equal fair play of desirable output, respectively assigns 1/3
Weight；In view of sharing 3 kinds of inputs, further averagely assign the weight for putting into part to capital, labour and the energy, i.e., it is various
The weight of input is respectively 1/9；Non- desirable output is also equally handled, will be two in chemical oxygen demand object discharge capacity, exhaust gas in waste water
Sulfur oxide emissions amount and cigarette (powder) dirt discharge capacity weigh the weight of each imparting 1/3.After considering environmental constraints, each provinces and regions in the whole nation entirely will
Plain energy efficiency results of measuring refers to table 2.
Each provinces and regions total-factor energy efficiency under 2 environmental constraints of table
Note：1. the efficiency value θ in efficiency ranking, that is, formula (5) in tablek, weight matrix for (1/9.1/9,1/9,1/3,
1/9.1/9,1/9)。
②《New China's compilation of statistical data in 60 years》With《China Statistical Yearbook》.
3. the calculating of material values storage employs continuous inventory method, the method for employing single hero (2008).
4. substance base stock and actual GDP are calculated with nineteen fifty-two fixed price.
After using environmental pollution as non-desirable output, 2010, Fujian, Shanghai and Jiangxi were in efficiency leading surface
Row 4,5 are divided in province, the i.e. optimum level in energy efficiency, Guangdong and Beijing, and Henan ranks the 23rd.Fujian in 2014 and
Shanghai is still the highest province of energy efficiency, and as Beijing highly energy-consuming trade moves outside, the energy efficiency of Beijing is promoted to the
Three, and the 23rd, the whole nation is ranked in Henan Province, is further expanded with the gap of national optimal level.As it can be seen that environmental constraints are received
After entering appraisement system, the energy efficiency in Henan Province be in the whole nation fall behind it is horizontal, illustrate the current energy utilization patterns in Henan Province and
Industrial system is still more extensive, and the transition progress of economic structure and energy resource structure lags behind average national level, Henan Province
It needs to accelerate the upgrading of Promoting Industrial constructional transfer, accelerates to promote clean energy resource consumption proportion.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
