Weak　employee　loyalty　has　always　been　one　of　the　most　serious　problems　faced　by　manufacturing　enterprises.　It　is　of　great　practical　significance　for　analyzing　the　affecting　factors　of　employee　loyalty　to　build　structural　equation　model　around　junior　staff　loyalty　of　manufacturing　enterprises.　The　results　show　that　employees＇　personal　feelings　exert　the　most　significant　influence　on　their　loyalty,　and　the　employees　are　more　concerned　about　the　future　development　of　enterprise　and　employee　professional　development.　Compared　with　remuneration,　employees　put　more　value　on　non-financial　rewards,　such　as　working　environment,　communication　with　leaders　and　staff　training　opportunities,　which　will　affect　their　loyalty　and　working　performance,　therefore,　enterprises　should　pay　attention　to　non-economic　compensation.　Employees＇　job　performance　has　a　greater　impact　on　their　loyalty:　a　higher　attendance　rate　or　better　job　performance　is　usually　associated　with　higher　loyalty　to　their　employers.　According　to　our　analysis,　manufacturing　enterprises　should　take　measures　on　human　resources　management,　enterprise　environment　and　other　aspects　to　improve　their　employee　loyalty.　©　2011　IEEE.
