According to Arrow’s Impossibility Theorem (that is, it is impossible to deduce the group preference order from the individual preference order)，True public needs are impossible to display accurately，Big data may subvert this theorem。By comparing different areas、Analysis of big data generated by different groups of people when receiving public services and conducting other activities，Can quickly identify more real public needs。Integrate common public needs，Respond promptly，Quickly form public decisions，And make timely adjustments and corrections，Thus achieving on-demand supply of public services。

Public service big data includes: service object data、Service policy data、Exchange interactive data、Service facility data、Service staff data、Service Fund Data、Service item data、Service performance data, etc.。Discover big data for public needs，Part of it is the direct big data generated by the public’s active expressions in the process of public services，The other part is the indirect big data formed by other related and non-related behaviors of the public，Hidden demand information can be discovered through refining analysis。

Bet365 app download Big data technology enables a variety of massive public voices to be recorded、Save，Make it more necessary for the government to respond to public needs in a timely manner、Respond seriously，Thus improving the efficiency of public service supply decision-making、Scientific degree of decision-making and service quality。For example，Through big data，Public services targeting some groups，Can more accurately determine whether a person needs it、Suitable for this service，And whether you are eligible to enjoy this service。If an elderly person needs care services，Some type、Whether people with a certain level of disability can obtain certain rehabilitation services，Wait。

Big data is not only useful for government public services，Government data can also help guide non-governmental forces to clarify the targets they serve、Content and method。Conducive to the relationship between upper and lower levels of government、Between different government departments、Integrating resources between government and non-governmental organizations，Optimized configuration，Realizing collaborative supply of public services，Reduce the disadvantages caused by fragmented supply。

　　Improving the level of public services

The application of big data is conducive to improving the supply of public services。The sharing of big data is conducive to improving the application and approval process of public services，Improve efficiency，Convenience to the public，Reduce welfare fraud、Secret operations and rent-seeking。For example，In social assistance services、The service access of vulnerable groups in housing services can be accurately determined through big data。At the same time，bet365 best casino games Big data is also beneficial to public services for the floating population，Especially public services for migrant workers in cities，Enable migrant workers and their children with complicated mobility situations to obtain relevant services in migrant areas in a timely manner。

For specific public service methods，Big data can improve effectiveness。For example，Using big data in public health and medical health services，Especially diagnosis and treatment big data、Utilization of clinical big data，To improve the judgment of diseases and the selection and adjustment of treatment methods，It has a great effect。Primary medical institutions can also use shared big data to improve diagnosis and treatment。For city buses，Big data is beneficial to vehicle deployment、Optimization of lines、Bus priority setting、Prediction of arrival time, etc.。Big data is also conducive to automatic inspection of the operation of public service facilities around the clock，Repair problems promptly。For example, public fitness equipment、Street trees、Street light、Fire hydrant、Park seats and other public facilities，By sensing、Monitoring devices can quickly identify operating conditions。Using big data in education，Can discover the personality of students、Specialties、Interest、Knowledge accumulation、Learning ability、Knowledge accumulation，Teach students in accordance with their aptitude，Meet students’ learning needs，Improve learning effectiveness。Remote primary and secondary schools can use shared big data to improve teaching standards。

The application of big data is conducive to improving the provision of public services。Digital library built through big data、Digital Museum、Digital Art Museum、Digital display Bet365 lotto review of immovable cultural relics，Not only can the public stay at home or not on the ground，You can obtain corresponding public cultural services，And get a three-dimensional panorama、Human-computer interaction、Virtual Reality (VR)、Experiences not found in real-life services such as augmented reality (AR)。

The application of big data is beneficial to the government’s public service supervision。The government’s public service departments、Public service agency、Public welfare organizations and market public service entities bear regulatory responsibilities。Social credit system formed by using big data，Credit supervision can be carried out on public welfare organizations and enterprises engaged in public services，It is also beneficial to the government’s purchase of services、Government financial subsidies、Scientific decision-making on government punishment and other matters，It can also promote government honesty and trustworthiness。For example，Monitoring the hospital’s medical insurance diagnosis and treatment behavior through big data，Can effectively reduce excessive medical treatment，Curb insurance fraud，Control the excessive growth of medical insurance expenditures。

In addition，The application of big data is also conducive to real-time monitoring and dynamic management of the public service supply process，Conducive to more accurate performance evaluation of public service providers，Especially external performance evaluation。

　Face up to the shortcomings of technology and promote technology application

The use of big data may cause privacy violations、Threat to freedom、Data dictatorship、Data only theory、Disadvantages such as big dataism，Applications in public services are Bet365 lotto review no exception。For example，Analysis and use of interactive communication data between supply and demand for public services，Considering that there are many falsehoods in the virtual space、Excessive、Emotional、Untrue、Irrational expression，How to extract the true public opinion is a difficult problem。Over-reliance on data、It’s scary to let data decide everything，Rely only on data support to make public service decisions，It will lead to the lack of humanistic care、Value-oriented deviation、Weakening of fairness and justice。Instrumental rationality cannot replace value rationality，For example，In education, it is not advisable to evaluate students and recruit teachers based solely on test scores。

Application of big data in public services，Need a big data platform for government and society，Data processing required by government and society、Analysis、Development Agency，Need the opening of government data and the exchange of enterprise data、Transaction，Requires related hardware、Software、Technology、Service、Talent、Funds，These are undoubtedly the contents of the development of the big data industry、Guarantee and boost。

The government has the following ways to strengthen the application of big data in the provision of public services。1.The government uses its own big data。Barriers should be broken down between various public service departments of the government，Realize data sharing，Thus promoting the formation of big data。Government data must not only be exchanged、Share，More analysis is needed、Use。The government can set up departmental and cross-department big data development agencies，You can also outsource Bet365 app download some data to professional companies、Processed by research institutions、Analysis。2.The government purchases big data from enterprises for public services。Big data includes big data owned by the government and big data owned by enterprises，The ideal situation is that the two are open to each other、Mutual use，But in reality when it comes to cost and profit issues，Often difficult to achieve。If the government needs big data owned by enterprises (including commercial databases) to provide public services，Purchasing is also possible。3.The government opens big data to public service enterprises and charity organizations。Public service enterprises under government regulation，Is one of the main providers of public services。Also，Public welfare organizations are also increasingly important suppliers of public services。The government actively opens the public service big data it generates and controls to them，Can promote the utilization of big data。For example，Urban traffic control departments open their own big data to navigation software companies，Enable public transportation services to alleviate congestion、Play a role in facilitating travel。Of course，The opening of government big data can be free，It can also be appropriately paid。

For big data companies，Applications in public services are also a market opportunity。For example，The Australian Public Service Big Data Strategy released in 2013 promoted the application of big data in the country’s public services。In our country，In 2015, the General Office of the State Council issued "Several Opinions on Using Big Data to Strengthen Services and Supervision of Market Entities"，On this basis，We should further bet365 live casino games promote the strategy and policy of “using big data to strengthen public services”，Adopt comments、Planning and other forms promote the application of big data in my country’s public services。
