17、ect of various factors5.1.1 the analysis of national tourism revenuetourism is a industry that is remarkably affected by social factors. once society have unusual happened, it can make tourism bought inhibit or positive impact. the expo held in shanghai, will increase chinas reputation to some degre

18、e and attract large numbers of tourists at home and abroad. in 2000 the tourism revenues until 2009, such as shown in table 1. table 1 2000 until 2009 tourism revenue unit: billion yuanyear2000200120022003200420052006200720082009tourism revenues4519499555664882682076868935109571160012900in order to

19、study the effects of expo how, we use until 2009 tourism revenues to estimate of year 2010 tourism income, 2000 in 2009 tourism income drawn scatterplot chart shown, as shown in figure 1.figure 1 tourism revenues and year relations scatterplot chartthrough the scatterplot chart easily found in 2003,

20、 except the data anomalies in 2003, tourism revenues outside kept a level for abnormal growth, easy to understand, according to a 2003 are analyzed, the 2003 domestic and worldwide the spread of sars, seriously affecting tourism. we delete 2003 abnormal data, and other data roughly into a straight l

21、ine growth, establish a linear regression mode.l.using least-square method for solving the correlation coefficient. ,且.by the correlation coefficient knowable, its value is close to 1, regression equation is remarkable.inspection parameters f value is larger, regression equation markedly, the probab

22、ility of f is, to explain the built model that was established,we get the regression equation for: , put into equations obtained without considering opening bid for the expo (refers to the world expo success but not yet started) under the condition of the tourism revenues in 2010, its result for the

23、 prediction: 13894 billion yuan.after the world expo 2010, we use the first half of tourism revenue to predict 2010 year tourism revenue. we assume the first and the second half of the same tourism revenue in 2010. the first-half tourism revenue is 75 million yuan in 2010. since the second half of t

24、he data is currently unavailable,but we can use half a years estimated annual data .we can get considering the world expo in 2010 under the condition of tourism revenues of approximately $15,000 billion yuan. according to the internet provides experts predict data floating billion yuan ,we measure w

25、ith the prediction error during the first half of 4%, error is not large.we may define the expo directly affect benefit factor for tourismthus we can get , is greater than 1 ,which shows the shanghai world expo tourism to produce a leading role.is the stronger the leading role.5.1.2 infrastructure c

26、onstruction total investment analysisin order to successfully host the world exposition, shanghai will build some infrastructure and increase investment in environmental protection, and these infrastructure to build before the start of the expo, because of the 2009 infrastructure construction total

27、to consider expo data,from 1995 to 2009 shanghai infrastructure investment as shown in chart 2. table 2 from 1995 to 2009 shanghai infrastructure units: billion yuanyear19951996199719981999200020012002infrastructure construction273.78378.78412.85531.38501.39449.90510.78583.49year20032004200520062007

33、2777.31therefore,we can map out import and export trade of scatterplot chart, as figure 3 shows that, by graph of the 2009 declined, this is due to the international financial crisis to import and export trade brings inhibition.figure 3 import and export trade of scatterplot chartfrom the scatterplo

34、t chart we are not easy to see the regularity of data, so original data accumulation generation and accumulation generations main purpose is to put the nonnegative of numbers or any irregular sequence into the filamentous columns. transformed into the data tend to have certain regularity. using afte

35、r conversion of data, drawings, as shown in figure 4 roughly movements as shown.figure 4 accumulated generation after data trendwe can see from the chart 4 after 2003 roughly a straight-line growth in 2005, after some more obvious respectively, the 2003, 2004, 2005 after a fitting data, through comp

36、arison and analysis, as shown in figure 5 shows, in 2005 after data will be fitted in the results minimum error.figure 5 2005 after data fitting figurethus we can gain a fitting function for: , through this function prediction of 2010 accumulation generation value for 21669.79 billion dollars, and i

37、ts accumulation generation with 2009 18934.02 billion dollars for poor value, we finally obtained import and export volume of 2010 for 2735.77 billion dollars.through the predicted values and the relative error accumulation generation value are analyzed, such as shown in table 4, it can be seen that

38、 the relative error is lesser, accumulation generation of practical value is more accurate.table 4 predicted values and relative error accumulation generation value analysisyearpredictionaccumulation generation actual valuethe relative error %20057540.947830.72-0.03701200610366.7110105.620.025836200
