大数据应用的关键点是数据来源、产品化和价值创造，数据资源和质量不足、应用场景较少以及创值能力差，严重制约了大数据应用。大数据应用前景广阔，但数据资源分布不均，在数据密集领域更易获得突破。促进大数据产业发展，需要政府开放数据资源并率先垂范，关键是要对不当的行业管理模式进行改革以促进大数据在已有各个行业中的应用。
The key of the big data application is the data source，productionalization and value creation. However，the lack and poor quality of the data source，shortage of the applied scene and poor of creation ability have seriously restricted the big data application.

Meanwhile，the data source is uneven distributed.It is a necessary for the government to open the data source to promote the big data industry development，especially to reform the inappropriate industrial management mode which will enhance the existed big data application.
