1、Jilin Provinces population growth and energy consumption analysisDemonstrationIllustrationConduction & suggestionEnglishMajor Statistics Student No. 0401083710 Name Niu Fukuan Jilin Provinces population growth andenergy consumption analysisSummarySince the third technological revolution, the energy
2、has become the lifeline of national economy, while the energy on Earth is limited, so in between the major powers led to a number of oil-related or simply a war for oil. In order to compete on the worlds resources and energy control, led to the outbreak of two world wars. Chinas current consumption
3、period coincided with the advent of high-energy, CNPC, Sinopec, CNOOC three state-owned oil giants have been going out to develop international markets, Jilin Province as Chinas energy output and energy consumption province, is also active in the energy corresponding diplomacy. Economic globalizatio
4、n and increasingly fierce competition in the energy environment, Chinas energy policy is still there are many imperfections, to a certain extent, affect the energy and population development of Jilin Province, China and even to some extent can be said existing population crisis is the energy crisis.
5、KeywordEnergy consumption; Population; Growth; Analysis;Data sourceI select data from China Statistical Yearbook 2009 Jilin Province 1995-2007 comprehensive annual financial data (Table 1).

11、iversal life energy consumption (kg of standard coal) index showed a rising trend, the total population of the annual data series Xt and national annual energy consumption data sequence Yt not smooth, the two may have long-term cointegration relationship.2. Data smoothing(1)Sequence Logarithm Figure
12、s 1 and 2 by the intuitive discovery data sequence Xt and Yt showed a significant growth trend, a significant non-stationary sequence. Therefore, the total population of first sequence Xt and universal life energy consumption (kg of standard coal) Yt, respectively for the number of treatment to elim
13、inate heteroscedasticity. That logx = lnXt, logy = lnYt, with a view to the target sequence into the linear trend trend sequence, by EVIEWS software operations, the number of sequence timing diagram, in which the population sequence logx timing diagram shown in Figure 3, the full sequence of energy
14、consumption logy timing diagram shown in Figure 4.Figure3 Figure 4Figure 3 shows the total population observed sequence logx and universal life energy consumption (kg of standard coal) sequence logy index trend has been basically eliminated, the two have obvious long-term cointegration relationship,
15、 which is the transfer function modeling an important prerequisite. However, the above sequence of numbers is still non-stationary series. Respectively logx and logy sequence of ADF unit root test (Table 5 and Table 6), the test results as shown below.(2)Unit root testHere we will be on the provinces total population and the whole sequence Xt energy consumption (kg of standard coal) sequence data Yt be the unit root test, the results obtained by Eviews software operation is as follows:Table 2 Of the total population sequence logxObtained from Table 2: Total population sequence data Xt of the
