Praised as gathering together the auspicious electronic race apparatus of the brand of the first nationality, the output reached 7,000 in that year, the sales volume reaches 5,000, has held the beginning of producing the domestic electronic race apparatus. Up to the production capacity of producing 100,000 per year by 2004 through the technological transformation not stopping , sell race apparatus 4 in the same year. 80,000, output value is 93,600,000 yuan, income from sales is 72 million yuan, finished ISO9001 and European Union CE authentication at the same time , and is chosen as leading brand products in Shandong.Gather together the auspicious electronic race apparatus in order to expand the production scale , the resources of production of rational utilization, successively for some domestic enterprises sticking brand production , improved the domestic occupation rate of the electronic race apparatus greatly, have offer for numerous enterprises and develop samples too, has driven the flourishing development of the whole trade.The electricity runs: Fashionable body-building products of the fairly comfortable lifeAt present, enterprises which produce the electronic race apparatus centre in the coastal area of the Changjiang Delta , Shandong Peninsula , Guangdong , Fujian, the total amount is about more than 50, it is about 15 that possess scale among them, and the joint-venture , proprietorship account for 50%.The electronic race apparatus is the integrated products of electromechanics, adopt assembler language programming, control with the computer, it is the development trade that the country encourages . The development of this product has driven making, plastic products , electronics industry of steel tube , electrical machinery industry ,etc. series develop , make people health is it limit by place , environment , climate to do exercises, contain physical training in recreation amusement, improve the national physique in an all-round way. In this production course, there are not pollutant and harmful substance that are produced , purchase the steel , plastic fittings outside, the electronic devices and components are assembled, is the green manufacture industryThe Central Party Committee which regards Hu Jintao as the General Secretary advocates building harmonious and orderly development environment in a more cost-effective manner, the development of the electronic race apparatus sticks to this theme closely, is playing an important role in driving the trade structural adjustment. Raise through the national income entering the well-off society, the electronic race apparatus begins to enter the family too in recent years, it for example cant gather together the auspicious brand race apparatus not electronic in in, sales volumes of small city chase there arent annual increment, a lot of urban and rural residents growing rich choose this superior way of building up body one after another , the race apparatus designed in large quantities of humanization is coming out, improve through electronic technology , the technology of the computer , transformation of making the equipment frock , its development space is very big, is a kind of products with sustainable development prospectThree major key elements of promoting national economy to increase healthily are consumption , investment , net export. The development of and the electronic race apparatus, occupy very great proportion among them. One that is with domestic Engel coefficient constant to reduce, by clothing,food,lodging and transportion to raise life quality develop people, the electronic race apparatus will be the optimum seeking apparatus of compatriots fitness , because by the look of experience of foreign countries, go on balance temper and become the fashion at electronic race apparatus. Classifying looking from national economy, it belongs to the tertiary industry that sports is consumed, it exceeds 10% in succession to accelerate in recent years, and the speed is accelerated year by year. The share of spuring grwoth of the national economic of consumption of sports and keeping fit will inevitablely continue increasing . This kind of fitness is consumed and contained relatively widely, have both consumption of resident and public consumption (such as health club ), its consumption acceleration rate exceeds 20%, among them, the electronic race apparatus exceeds 40%, have stronger growth momentum.Intellectual property right and trade frictionThe intellectual property right becomes soft rib of the sports goods industry of our country, it is the production that because we are correlated with to market economy and with the sports products, it invent, trade,etc. the knowledge one possession, belong to, know little about game the rules and laws and regulations and the information not relevant not transfer. One sports apparatus or equipment know which country invent , others had already registered unexpectedly, under the situation which contents are registered, but we have produced and sold for many years. Not merely the style , structure are the same for some products, even appearance , color are very close , the more sad one is, because to to ignore above-mentioned situation, we hold oneself is it reach product this birthplace go for exhibiting , sale to produce also, we say , an invention technology or the patented product must go through long and difficult exploration and study , It has condensed the intelligence and energies of the scientific research personnel of sports, the original inventor has paid hardships of going beyond the normal condition for this, ought to receive the protection of the respect and law of the society . One of market obtain products that patent sanction is it copy to copy producer of us already in our country, there is not innovation , this not merely serious others patent for invention of infringement at all, Make the bringing the doctrine and entering into the mistaken idea in vogue for a time of sports goods industry of our country too. Do it in this way, in comparatively close planned economic system, may little someone find or investigate , but today, the gateway of a country is opened further, we must pay a price for this . In 2001, our family participated in U.S.A.s super exhibition, the sample was just a exhibition, have been detained all products, carry on negotiations several times and make a self-criticism in writing on the grounds of infringing by others, have paid the expensive fine finally; This year, at the rich meeting of German body, the exhibit of another enterprise of ours is asserted and infringed, the other side must speak to and does not forgive people , our enterprises admit a fault , ready to pay the penalty and does not miss , and humiliate this enterprise by every means in public , pass the diplomatic channel finally, the embassy negotiates, has dealt with this . Happen when this kind of case is on our countrys market , on the body of our enterprise, the normal order that has not merely disrupted the market, has infringed the interests of rights and interests people, have reduce the international reputation of made in China , has damaged the public image of reform and opening-up of our country too.After our country enters the WTO , the self-satisfied Chinese brand is trying hard to seize the opportunity, while going abroad, the western developed country has made the strategic defence in time with this, set up to of our country sports goods including technology , standard , getting green environmental protection , move plant protection , anti-dumping , intellectual property right , community responsibility dishes of dishes of barrier, close down , stop the entry of the like product with the extremely unkind clause . Meanwhile, they also used three unique skills , first, strengthened the registered dynamics to the patented technology of the products. In 2002, accounted for 5 at home in our country authorized the patent for invention. 2%, and accounts for 76 abroad. 1%; Accounts for 3 at home in the post with high technical advantage is invented. 6%, and accounts for 96 abroad. 2%.Second, the one that strengthened to the market of our country was monitored . In order to safeguard its ones own image and interests, attack the rival, the external brand is sent full-time or hire personnel, but the great majority are still the commercial networks utilizing the whole country to open, carry on omni-directional monitoring to the market of our country. They carry on the investigation to classification of the goods , selling structure , product cost and consumer demand in the name of surveying and studying the market. A main one to investigate tort of all kinds of of the like product, including product design , appearance , inside structure , enterprise identification and various kinds of datum ,etc., then assemble the picture , material object and written historical materials in the policy-making level of the company in time. On the market not normal of our country at present, all kinds of imitate , infringe the phenomenon and exist seriously, they once opportunity ripe, can hit out severely, never soft, as to this we must highly watch out for .Third, strengthen and is protected and put to the customs on record and applied working. The external brand tries hard to solve from flowing into outside the border and from exporting to the fake and forged products of the overseas market within the border through this kind of way , have domestic and international 1300 more than share is it is it involve thousands of of brand to apply to put on record 2003, through to protect jointly the whole country all pass, have notable effect.Because of the absolute predominance in price of sports goods of our country , make international trade rub constantly, embody in the anti-dumping mainly. Taking sports shoes as an example, our country is the manufacture big country of sports shoes in the world, because the domestic market is limited in capacity, the majority depended on exporting, 2003, exported about 3,200 million pairs. Nike shoes the whole world sell 60% China production, beautiful Tianjin strong shoes the whole world sell 90% make for China, world shoes-making big country Spain have 14 sports shoes factory, sports shoes that China makes import more than 70 million pairs every year, price of each pair of ordinary sports shoes is more than 20 euro on this countrys market. And the sports shoes price of 3-2 euro of equal quality which China make.In OEM business, our country processes about about 3 dollars for a pair of better sports shoes profit, processing one racket 1-2 U.S. dollar, make one have 70 more than air gun profit that part make up in 10 dollars about, processing is about in 7-8 dollars a top-grade sportswear. But once products that China make these stick identification , world of famous brand, know personal value ten to dozens of times. China span and weave the big country in the world at the same time , after protection period, clothing quota cancels the global fabrics, the sportswears of our country will gain larger development space on the international market. A large amount of good and inexpensive made in China enters the international market, has brought the generous profit to businessmen of various countries, great too amazing and national consumer market, The ones that caused the importer are panic and uneasy at the same time, they regard made in China as dreadful monsters, is it seize market of them to think, then claim case , case of encroachment of right , anti-dumping probe , cook shoes incident ,etc. to is it discriminate against restriction incident of color happen again and again seriously to have, it is estimated after protection period, this kind of incident will still continue happenning.No famous brand , no competitivenessThe precedence accounted for in national economy of sports industry of the developed country ranks more than ten location , main trade and main power of grwoth of the national economic, because our country trade this does not unify and not centralized lacking regulation and control that putting in place and counting systemming, so, guide and encourage the momentum of this industry development to lag behind correspondingly . But with the deepening development and drive of the Olympic Games economy of the national fitness campaign, regard famous-brand strategy implementation as opportunity, combine industrial structure constantly, the trade will demonstrate important status of national economy their more and more.The manufacturing industry of the foreign electronic race apparatus started since last century later stage of the seventies, compared with like product in our country, except that have and relatively take the lead in style diversification and surtax functional development, other disparity are relatively small. Such as steel, the belted steel that my national treasure steel , Anshan Iron and Steel Plant ,etc. produce reaches or exceeds the international standard , related steel tube its is it reach foreign standard too to make, electrical machinery wait for electricity run fittings is it digest and assimilate to adopt, we develop in the international advanced ranks from material to new style. So, the electronic race apparatus is different from the plane , automobile trade , nearly have little disparity with advanced level in foreign countries. Therefore, the internationally famous electricity runs in the manufacturing enterprise and pays close attention to day by day, has already begun to let enterprises of our country produce sticking to brand products for it.Though growth momentum fine, domestic electricity run circumstances at domestic and international markets or have difference. Main reason not strong of the competitiveness in the international market of the domestic electronic race apparatus, lack the effect of leading brand products. And compared with overseas enterprise start than such reasons as the impact to the market for late , some fake and forged production of small enterprise ,etc., have weakened the market competitiveness of the domestic electronic race apparatus tooAt present,love brand not internationally famous health , strength strong in, must true, space, having a match there arent one hundred, some furnish a huge amount of money for making the investment and founding the factory, and exert pressure to domestic enterprises with higher brand awareness, under this situation , promote the emergence of leading brand products of electronic race apparatus as soon as possible, can yet be regarded as the government and promote one of the national industry of the electronic race apparatus effectively, promote national brand and domestic product raise a heavy shortcut , international market of competitiveness too. In a situation that the international market competition of the electronic race apparatus is fierce , domestic product will you please win , could move forward in close relations effectively in time with famous brand strategy.The strong promotion of the Whole-Peop1e Health-Building Plan, the pulling of sports consumption of the Olympic Games economy, drive the tremendous development of the sports industry effectively, have far-reaching meanings in promoting the public cognition degree of the Chinese sports goods, to the development of the sports goods industry including electronic race apparatus, to the whole promotion promoting the sports goods industry trade, construct scale merit, enter the global markets , will all offer a large stage, sports and keeping fit undertaking and the Olympic Games economy are all calling Chinas famous brand , the electronic race apparatus is calling Chinas famous brand .电动跑步机行业呼唤中国名牌国产电跑第一家 1996年之前,电动跑步机都是国外产品，进入家庭的大都是由自行车厂改制的生产厂制造的机械跑步机,国人对价格几万乃至十几万元的进口电动跑步机望而生畏。 1993年以后，随着国际产业结构的调整，韩国企业向我国转移，首先是山东祥和集团公司利用该地区电机、控制电源生产的优势，于1994年组建了专厂，通过充实机加工能力，结合国内外信息，祥和集团于1995年生产出了全部为自制部件的家用电动跑步机，并于次年的南昌体博会上参展。被誉为第一个民族品牌的汇祥电动跑步机，当年产量达到七千台，销量达到五千台，开了生产国产电动跑步机的先河。通过不停的技术改造，到2004年达到了年产十万台的生产能力，同年销售跑步机4.8万台，产值9360万元，销售收入7200万元，同时完成了ISO9001及欧盟CE认证，并被评为山东名牌产品。 汇祥电动跑步机为扩大生产规模，合理利用生产资源，先后为一些国产企业贴牌生产，极大地提高了电动跑步机的国产占有率，也为众多企业提供了发展样品，带动了整个行业的蓬勃发展。电跑:小康生活的时尚健身产品 目前，生产电动跑步机的企业集中在长江三角洲、山东半岛及粤、闽沿海地区，总数约为50余家，其中具备规模的约为15家，而合资、独资企业约占50%。 电动跑步机系机电一体化产品，采用汇编语言编程，用计算机控制，系国家鼓励的发展行业。该产品的发展带动了钢管制造、塑料制品、电子工业，电机工业等系列发展，使人们身体锻炼不受场地、环境、气候的制约，寓体育锻炼于休闲娱乐之中，全面提高国民身体素质。该产品制作过程中，无污染物及有害物质产生，外采购钢铁、塑料配件，电子元器件组装，是绿色制造产业。 以胡锦涛为总书记的党中央大力倡导建设和谐有序的发展环境，电动跑步机的发展就紧贴这一主题，为带动行业结构调整发挥着重要作用。通过进入小康社会的国民收入提高，电动跑步机近年来也开始进入家庭，例如汇祥牌电动跑步机在中、小城市的销售量逐年增量超过50%，许多富裕起来的城乡居民纷纷选择这一优越的健身方式，一大批人性化设计的跑步机正在问世，通过电子技术、计算机技术、制造设备工装的改造革新，其发展空间很大，是一种有可持续发展前途的产品。促进国民经济健康增长的三大要素为消费、投资、净出口。而电动跑步机的发展，在其中占有很大比重。随着国内恩格尔系数的不断降低，人们由衣食住行向提高生活质量发展，电动跑步机将是国人健身的优选器材，因为，从国外的经验看，在电动跑步机上进行平衡锻炼已经成为时尚。从国民经济分类看，体育消费属第三产业，近年增速连续超过10%，而且速度逐年加快。体育健身的消费拉动国民经济增长的份额必然会继续增加。这种健身消费涵盖较广，既有居民消费又有公共消费（如健身俱乐部等），它的消费增速超过20%，其中，电动跑步机超过40%，具有较强的发展势头。、知识产权与贸易摩擦 知识产权之所以成为我国体育用品业的“软肋”，是因为我们对市场经济以及与体育产品相关的生产、发明、贸易、等知
