1、 Data authenticity
Let's start with the source of trade data.
Trade data of foreign trade States is a first-hand data purchased from the official customs agencies of various countries. The formal source channels allow commercial use. High data integrity and continuous update are a point to distinguish data quality. And in the process of using data, we can easily judge whether the data source is normal or not through the content of data.
The content of trade data is divided into two parts: one is purchasing information and the other is the list of purchasers. The real purchasing information, which provides the data of the bill of lading and customs clearance, includes the data of the national bill of lading and the customs import and export declaration information, all of which record the real import and export transactions of each country. Because the sea bill of lading is a non-standard document, not only the contents and styles of the field of the bill of lading in different countries, but also do not strictly require the specification and format when filling in. In addition, the contents of the fields disclosed by various countries are not uniform, so there are also inferior data in the market, and the trade data are fake by customs statistics and the list of purchasers.
This is very good to distinguish. We can verify through two methods. One of the above mentioned methods is whether the data provided can be kept updated continuously after purchasing the data. The other is to provide the data of submitting and closing documents, and we can see whether the detailed transaction records of both parties are collected or only the list of purchasers.
After getting access to channels and content, let's say, "is it legal to use trade data? “
2、 Data legitimacy
First, one said one. As early as 1996, the United States has promulgated its own trade data worldwide through government legislation and authorized professional companies to operate commercialized. Open trade data is in the interests of the country and is beneficial to economic development, and is an inevitable trend of international trade. After that, more and more first-line countries and regions have also disclosed their trade data. Of course, each country has strict legal provisions on information disclosure and public content. It is inconsistent to disclose what content and what information is disclosed.
Next, let's talk about whether trade data can be used in China? In fact, in the 1990s, China began to introduce open trade data, and then there were service providers joining the trade data service industry. Now more than 100 companies in China are providing data services. At present, the state vigorously encourages foreign trade export, and the export policy does not explicitly restrict the use of foreign trade data. Moreover, the trade data of the first-line countries that have been opened and published are true and legal. We can use them at ease.
