【摘要】：隨著河北省大面積霧霾天氣的頻繁出現(xiàn),與人類生存息息相關(guān)的大氣污染問題越來越受重視。環(huán)保投資作為降低污染物排放的重要手段,是改善大氣污染現(xiàn)狀的必要條件。本文主要研究河北省環(huán)保投資(治理工業(yè)廢氣投資)對工業(yè)廢氣排放的影響。本文在已有文獻(xiàn)研究的基礎(chǔ)上,提出環(huán)保投資可以通過規(guī)模、結(jié)構(gòu)和技術(shù)效應(yīng)實現(xiàn)工業(yè)廢氣減排的假設(shè)。通過描述性統(tǒng)計分析了河北省環(huán)保投資和工業(yè)廢氣排放的基本情況。并基于1996-2014年的統(tǒng)計數(shù)據(jù),運用多元回歸模型,考察河北省治理工業(yè)廢氣投資與工業(yè)廢氣排放及相關(guān)變量之間關(guān)系;然后利用對數(shù)平均迪氏分解法(LMDI),將河北省工業(yè)廢氣排放總效應(yīng)分解為三種因素:規(guī)模效應(yīng)、結(jié)構(gòu)效應(yīng)和技術(shù)效應(yīng),并對重點行業(yè)進(jìn)行了單獨分解;最后運用多元線性回歸模型考察河北省治理工業(yè)廢氣投資對三種效應(yīng)的影響。本文通過理論和實證研究得出以下結(jié)論:(1)本文分別對河北省工業(yè)廢氣排放總量和河北省重點行業(yè)廢氣排放量應(yīng)用LMDI因素分解法,將總效應(yīng)分解為規(guī)模、結(jié)構(gòu)和技術(shù)三種分效應(yīng)。從分解的結(jié)果看,無論是總量的分解結(jié)果還是重點行業(yè)的分解結(jié)果,規(guī)模效應(yīng)是促進(jìn)排放總量增加的主要因素,結(jié)構(gòu)效應(yīng)次之,而技術(shù)效應(yīng)是污染減排的主要因素。(2)河北省治理工業(yè)廢氣投資對河北省工業(yè)廢氣排放的減排效果并不顯著,這就導(dǎo)致河北省大面積霧霾天氣出現(xiàn);究其原因是河北省治理工業(yè)廢氣投資未能有效降低工業(yè)廢氣排放的規(guī)模效應(yīng)和結(jié)構(gòu)效應(yīng);雖然河北省治理工業(yè)廢氣投資對技術(shù)效應(yīng)存在負(fù)向影響,但是技術(shù)效應(yīng)的減排作用較小。因此,河北省現(xiàn)階段應(yīng)該繼續(xù)加大環(huán)保投資;同時結(jié)合供給側(cè)改革的步伐,轉(zhuǎn)變經(jīng)濟(jì)增長方式;特別是加快高耗能、高污染行業(yè)向低耗能、低污染行業(yè)的轉(zhuǎn)型;此外,還應(yīng)加強(qiáng)環(huán)境監(jiān)管并加大企業(yè)研發(fā)投入,從而實現(xiàn)對河北省工業(yè)廢氣排放的有效控制。
[Abstract]:With the frequent appearance of haze weather in Hebei Province, more and more attention has been paid to the problem of air pollution, which is closely related to human survival. Environmental protection investment is an important means to reduce the emission of pollutants. It is a necessary condition to improve the present situation of air pollution. This paper mainly studies the effect of environmental protection investment (investment in treating industrial waste gas) on industrial waste gas emissions in Hebei Province. It is suggested that investment in environmental protection can be carried out through scale. This paper analyzes the basic situation of environmental protection investment and industrial waste gas emission in Hebei Province by descriptive statistics. It also bases on the statistical data from 1996 to 2014. The multivariate regression model was used to investigate the relationship between the investment in industrial waste gas treatment and industrial exhaust gas emissions and related variables in Hebei Province. Then, the total effect of industrial waste gas emissions in Hebei Province is decomposed into three factors: scale effect, structure effect and technical effect, and the key industries are decomposed separately by using the logarithmic average Dee decomposition method (LMDI). Finally, the effects of industrial waste gas investment on three kinds of effects in Hebei Province are investigated by using multiple linear regression model. The following conclusions are drawn by theoretical and empirical research: 1). In this paper, LMDI factor decomposition method is applied to the total amount of industrial waste gas emissions in Hebei Province and to the exhaust gas emissions of key industries in Hebei Province. The total effect is decomposed into three sub-effects: scale, structure and technology. From the result of decomposition, the scale effect is the main factor to promote the total emission increase, whether it is the decomposition result of the total amount or the decomposition result of the key industry. The structure effect is the second, while the technology effect is the main factor of the pollution reduction. This led to the emergence of a large area of haze weather in Hebei Province; The reason is that the scale effect and structure effect of industrial waste gas emission can not be effectively reduced in Hebei Province. Although there is a negative effect on technology effect in Hebei Province, the emission reduction effect of technology effect is relatively small. Therefore, Hebei Province should continue to increase investment in environmental protection at the present stage. At the same time, combining the pace of supply-side reform, changing the mode of economic growth; In particular, accelerate the transformation of high energy consumption, high pollution industry to low energy consumption, low pollution industry; In addition, it is necessary to strengthen environmental supervision and increase R & D investment of enterprises so as to realize effective control of industrial exhaust emissions in Hebei Province.
