Research of Transforming Grassroots Government Function Based On Principal Component Analysis

According to principal component analysis theory, through government functions of network platform, performance of organization departments, the software power and information reflected by public to participate in the government network platform construction, to improve the transformation of government function, establish a reasonable standard of government network platform. According to the four secondary indexes, it comprehensive develop 18 evaluation factors as the main factors and targets that influence transformation of town government functions, to get the weight proportion of each index, and analyze on the transformation of town government function in the network era.


Introduction
Computer network have a large number of users, according to 2014 statistics, Chinese internet users reached to 632 million, and mobile internet usage is growing fast.Government department consciously sorting and planning network platform, and its purpose are to constitute reasonable government networks.For now, the town government network platform is not very perfect, and lack of real-time attention and update for web information.In the internet age, the government network platform is effective channels and measures to reflect the public state and anticorrosive.Because ordinary petition or supervision need a long time and higher cost, so establish a efficient and reasonable government network platform is very important.

Construction of town government network platform
To speed up the urbanization construction is an important decision for coordinated developing urban and rural areas in China.Villages and towns function transformation is an important part of the change of government function [1] .With the further concept optimization of a service-oriented township government, to indicate the direction for town government to better serve the society, serve the public.So "service-oriented town government" is the functions orientation of town government in the new rural construction [2] .In terms of network system, the balance between individuals and organization market of network business and disciplinary and the township government is particularly important., selects a kind of index, on the condition of the economic factors, social factors, the network communication coexist [3] , based on principal component analysis to quantify the establishment of the town government network platform.Set up relationship of the target layer, criterion layer and project layer, as shown in table 1.
Target layer: construction of town government network platform.Rule layer: the influence factors of scheme, the functions of government network platform 1

Principal component analysis model theory
Through the above account, this article can be drawn three levels of indicators system about function evaluation of town government network platform.Among them, every level's factor analysis is extracted by lead level, and the weight is combine factor analysis and hierarchical analysis to study reasonably.
In this paper, by applying the principal component analysis method to determine the weight allocation rate and its matching principle as follow: Assuming it has n indicators, each indicator has p corresponding variable, thus has a n p u x x x } , analyze them synthetically, so corresponding indicator is: The ij l must be: The inconsistency test of A is valid, and movement in allowed range, weight vector can be substituted for A feature vector.Principal component analysis method calculated as followed: (1) Construct factor sets U, (2) Construct judge sets V, In the type, i x and j x related original variables are corresponding coefficient ij r i j 1 2 p) } , so its calculation formula is: ( 1,2, , ) The total contribution is Above all are the principal component analysis steps to calculate the objective weighting, and will specifically apply it.

Determination of factor index
By using the detection method of factor analysis for testing, the result is 0.879 .It shows that factor analysis can be done, but also proved that the factor analysis method is effective, according to the relevant data of each index, by using the method of principal component analysis to get the variance cumulative rate, as shown in table 3: Through the above table we can get: the larger load on functions of network platform are Y8, Y13; the bigger load on software power are Y5, Y7, Y12, Y18; the bigger load on the performance of all kinds of town government organization department are Y9, Y10, Y14, Y15, Y17; bigger load on public information are Y1, Y12, Y3, Y4, Y6, Y11.So we mainly study the multiage participation in network governance [4] , get the corresponding secondary indexes: network platform function, software, load reported by all the people, the performance of all kinds of organization department.Government network platform is based on the propagation theory and governance theory [5] , is not only the embodiment of the government management system, but also a kind of medium.

SHS Web of Conferences
Have above knowable, we can get the corresponding characteristic values for the four indicators, From the table we can score each factor coefficient matrix respectively, and using the matrix, respectively get scores of observation variable factor, as shown below: By the above calculation process, we obtain the evaluation index system of the town government network system functions, shown in the table below: Unified planning, unified standards, and integration of resources, global services are the goal of network information construction [6] .It aware that the composition analysis of the network functions transformation in the construction of towns network platform, can effectively assign responsibilities, allocate task.Based on shown in table 5, in order to clearly show the weight relationship between the network system function of towns government, the paper get as shown in the figure below:

Conclusions
Network media is the media based on the internet to spread information.And it reflects the government's decision-making and the real-time dynamic.Network platform is the most important media, also reflects the government image [7][8] .In the era of network, the construction of a reasonable government network platform is the effective channels and measures to react public information, anti-corrosion.This article based on principal component analysis to get the information reflect by various levels indicators of the government network platform functions, performance of all kinds of organization department, software power and information reflect by public, to study for the towns government function change.Through unit's influence and ICMETM 2015 02008-p.7 information uploading indexes' composition proportion, which established in this paper, we can get main aspect and evaluation system in town government platform.
