摘要：
Counter-terrorism policies are classified into three kinds based on the terrorism decision whether to commit terrorist acts. The policy effectiveness is probed quantitatively. We find: The early effectiveness of proactive policies is positive, while the effectiveness ceaselessly becomes weaker on the whole. Passive policies have long term effectiveness though overall effectiveness is small. The initial effectiveness of policies dealing with root causes is little. However, the significance gradually increases. Among proactive policies, the military attack functions better in the early stage compared with the politics attack, while its effectiveness becomes weaker in the later stage. Among passive policies, reinforcing the law and system is more significant than improving the embassy guard in both the short and long term.
摘要：
With the rapid development of China's economy, the agricultural industry chain has a new mode of operation. The rise of big data technology can collect the relevant information of the agricultural industry chain in all aspects more rapidly, accurately and comprehensively, so that the agricultural production, logistics and information flow can be unified, so as to realize the optimization of the resource structure of the industrial chain, and the operation efficiency is higher. In this paper, the analysis method combined with big data was used to construct the industrial chain of ecological agriculture. The ecological agriculture industry in Wuwei was regarded as the specific research object, and a large amount of empirical data was collected by means of consulting literatures and field surveys. The input analysis and output analysis of the agricultural production in Wuwei were carried out and the original industrial chain model was evaluated, and the deficiency of the influence factors was improved. The agricultural industry chain was the developmental situation of a dynamic organization, which had important methodological significances. This paper attempted to put forward some suggestions for the rational development of the agricultural industry chain.

With the continuous development of economy and the integration of the Internet information network, the network language is playing an increasingly important role in people's lives. Since the economists put forward the linguistic economics in 1965, the economic value of language has become the consensus of the people of all countries, and now it is a new and hot topic to study and analyze the English network language. In this paper, a system for evaluating the economic value of English network language was designed. Analytic hierarchy process (AHP) and qualitative methods were used, and the economic value of network language was quantified.

摘要：
As a new discipline in the world, language economics is developing rapidly in Europe and America. The language economics is an important field in economic trade. To explore economic value of language and the relationship between language and economy is the important content of the international financial and economic academic circles. Therefore, it is of great significance to study the development trend of foreign language economics researches, and it has a strategic guiding role for the development of domestic macroeconomic objectives. In view of this, in this article, the papers about language economics published in Europe and the United States in 2005-2015 were arranged and analyzed by using literature visualization analysis method, the frequency of the regional classification, the distribution of hot spots and key words discussed in this paper was got. Results show that the European and American language economics is more inclined to study the relationship between language and economic and trade development, which is strongly different from the domestic focus who emphasizes theoretical links, and this plays an important role in the future study of language economics in the future.
