电动执行器市场近几年十分活跃，竞争相当激烈。东亚和东南亚的电动执行器进出口增长迅速，北美的欧共体等发达国家间的市场贸易持续发展，德国、意大利、日本、中国等国家和地区的出口扩大，美国、英国、法国等国家进口的高速增长,形成了电动执行器市场繁荣的支撑点，再者，由于世界经济进一步化，跨国公司将不断推动电动执行器市场的发展，贸易地区化是毕成为另一大特点。
electric actuator market has been very active in recent years, and the competition is fierce.The import and export of the electric actuators in East and Southeast Asia has increased rapidly, and the market trade between the European Community and other developed countries in North America continues to develop. The exports of Germany, Italy, Japan, China and other countries and regions are expanding, and the import of the United States, the United Kingdom, France and other countries is increasing rapidly.In addition, as the world economy is further internationalized, transnational corporations will continue to promote the development of the international electric actuator market, and the regionalization of international trade becomes another major feature.
一、国内外电动执行器市场特征
一．The characteristics of the electric actuator market at home and abroad
从整个电动执行器市场来看，主要有两个：
From the whole electric actuator market, there are two main markets：
1、国内市场，国内市场又分新建、扩建程项目市场，老装置维修、改造项目市场。
1, the domestic market and the domestic market will be divided into the new construction and expansion project market, the old equipment repair and transformation project market.
从这两块市场来看，普通电动执行器产品严重供大于求，其次，企业之间竟相压仰，无序竞争，伪劣产品……，市场很不规范，导致某些电动执行器生产企业在惨烈的竞争中，连年大幅度亏损。从这两块市场的需求来看，随着市场经济的发展和完善，特别是进步世界贸易组织(WTO)，其市场变化越来越大，企业受市场的影响越来越深，用户对市场产品的需求越来越高，对产品开发、生产周期的需求越来越短。
From these two markets, the common electric actuator products are seriously oversupplied, and secondly, the enterprises are competing against each other, and there exists disorderly competition, counterfeiting and shoddy. The market is very irregular, causing some electric actuator manufacturers to lose substantially in the fierce competition.From the demand of these two markets, with the development and improvement of the market economy, especially the progressive World Trade Organization (WTO), the market changes a lot, the enterprises are more and more affected by the market, the demand for the market products is getting higher and higher, and the demand for the product development and production cycle is getting shorter and shorter.
2、国外市场。国外市场近几年十分活跃，竞争相当激烈。东亚和东南亚的电动执行器进出口增长迅速，北美的欧共体等发达国家间的市场贸易持续发展，德国、意大利、日本、中国等国家和地区的出口扩大，美国、英国、法国等国家进口的高速增长，形成了电动执行器市场繁荣的支撑点，再者，由于世界经济进一步化，跨国公司将不断推动电动执行器市场的发展，贸易地区化是毕成为另一大特点。
2,Foreign market. Foreign market has been very active in recent years and the competition is fierce..The import and export of the electric actuators in East and Southeast Asia has increased rapidly, and the market trade between the European Community and other developed countries in North America continues to develop. The exports of Germany, Italy, Japan, China and other countries and regions are expanding, and the import of the United States, the United Kingdom, France and other countries is increasing rapidly.In addition, as the world economy is further internationalized, transnational corporations will continue to promote the development of the international electric actuator market, and the regionalization of international trade becomes another major feature.
二、国内市场
二．Domestic market
我国电动执行器生产厂家约2300多个，能提供的电动执行器产品有几大类，3500多个品种，40000多个规格。
There are about more than 2300 electric actuator manufacturers in China. There are several categories, more than 3500 varieties and more than 40000 specifications of electric actuator products that can be provided.
(1)城市建筑用电动执行器：城建系统一般采用低压电动执行器，目前正向环保型和节能型方向发展。环保型的胶板阀、平衡阀及中线蝶阀、金属密封蝶阀正在逐渐取代低压铁制闸阀。国内城市建筑需用电动执行器多为平衡阀、软密封闸阀、蝶阀等。
(1) Urban building electric actuators：Urban construction systems generally use low pressure electric actuators, which are developing towards environmental protection and energy saving. environmentally-friendly rubber plate electric actuator, balance electric actuator, middle line butterfly electric actuator and metal seal butterfly electric actuator are gradually replacing low voltage iron gate electric actuators. Domestic urban buildings need to use electric actuators, such as balance electric actuator, soft seal gate electric actuator, butterfly electric actuator and so on.
(2)城市供热用电动执行器：城市代热系统中，需用大量的金属密封蝶阀、水平平衡阀及直埋式球阀、因这类阀解决管道纵向、横向水力失调问题，达到节能、代热平衡的目的。
(2)Urban heating electric actuator: in the urban heat generation system, a large number of metal sealing butterfly electric actuators, horizontal balance electric actuators and directly buried ball electric actuators are needed to solve the longitudinal and lateral hydraulic imbalance of the pipeline, so as to achieve the purpose of energy saving and heat balance.
(3)环保用电动执行器：国内环保系统中，给水系统主要用于中线蝶阀、软密封闸阀、球阀、排气阀(用于排除管道中的空气)。污水处理系统主要需用软密封闸阀、蝶阀。
(3) environmental protection electric actuator: In the domestic environmental protection system, the water supply system mainly needs the middle line butterfly electric actuator, the soft seal gate electric actuator, the ball electric actuator and the exhaust electric actuator (to exclude the air in the pipeline).
(4)城市燃气用电动执行器：城市燃气占整个天然全市场的22％，电动执行器用量大，其类型也多。主要需要球阀、旋塞阀、减压阀、安全阀。
(4) urban gas electric actuator:city gas accounts for 22% of the whole natural market, and the number of electric actuators is large. It mainly needs ball electric actuator, plug electric actuator, pressure reducing electric actuator and safety electric actuator.
