Based on your understanding, describe the Causes of unemployment in terms of economic reason.

One of the causes that lead to unemployment will be economic trends. Sometimes, when the trends have come, there will be a lot of new enterprises or people will start to open new businesses. However, if the trends pass, the demand for those products will start to fall and cause a lot of people to lose their jobs. This situation will be significant, especially in the industrial sector. This is because the industry sector uses more temporary contract workers to fit with the sudden increase in demand. While the trends are gone, demand goes down, and industries will fire and terminate most of the contract workers too.

导致失业的原因之一将是经济趋势。有时，当趋势来临时，会有很多新的企业或人们开始开辟新的业务。但是，如果趋势过去，对这些产品的需求将开始下降，并导致很多人失业。这种情况将很严重，尤其是在工业领域。这是因为该行业使用更多的临时合同工来适应需求的突然增加。虽然趋势消失了，需求下降，但行业也将解雇并解雇大部分合同工。

Even more, if there was economic depression, most the companies will start to fire unimportant employees to decrease the cost of human resources, even sometimes fire the employee who has a high salary just because of experience and hires new employees to save the cost. At this time, it would increase the unemployment rate too.

更有什者，如果经济不景气，大部分公司会开始解雇不重要的员工以降低人力资源成本，甚至有时会因为经验而解雇高薪员工并聘请新员工以节省成本。这个时候，失业率也会上升。

Other than that, the impact of technology is also one of the reasons. While new technology has been found, the economy will start to grow. But however, if the technology is about automation which is able to increase production for the economy, it will also cause a lot of unemployment rate too because machines have taken over people's jobs.

除此之外，技术的影响也是原因之一。虽然发现了新技术，但经济将开始增长。但是，如果这项技术是关于自动化的，它能够为经济增加产量，但它也会导致大量的失业率，因为机器已经取代了人们的工作。
