The　Beijing-Tianjin-Hebei　region　is　one　of　the　regions　with　the　most　dynamic　economies,　highest　degrees　of　openness,　strongest　innovation　capacities　and　largest　populations,　as　well　as　an　important　engine　driving　China’s　economic　development.　Currently,　the　development　of　the　BeijingTianjin-Hebei　region　faces　many　difficulties,　including　an　inefficient　distribution　of　regional　functions,　imbalance　in　industrial　structure,　low　sophistication,　and　serious　overburdening　of　resources　and　the　environment.　Promoting　the　overall　coordinated　development　of　the　region　has　become　an　urgent　challenge.　In　this　paper,　according　to　the　conventions　of　industrial　structure　optimization,　the　three　core　indicators　of　regional　industrial　structure　rationalization,　sophistication　and　ecologicalization　are　constructed.　With　the　help　of　the　grey　dynamic　correlation　model,　the　three　indicators　are　coupled　with　the　economic　growth　rate,　and　the　industrial　structure　optimization　index　of　the　Beijing-Tianjin-Hebei　region　is　comprehensively　measured.　The　study　shows　that　rationalization　of　the　industrial　structure　in　the　Beijing-Tianjin-Hebei　region　is　increasing　but　that　this　trend　is　not　obvious;　sophistication　of　the　industrial　structure　is　relatively　high　and　has　also　been　operating　at　a　high　level;　however,　the　overall　ecological　level　of　the　industrial　structure　in　the　Beijing-Tianjin-Hebei　region　is　not　high　and　presents　the　characteristics　of　high　in　the　middle　and　low　at　both　ends.　In　terms　of　the　relationship　between　industrial　structure　and　economic　growth　in　the　Beijing-Tianjin-Hebei　region,　ecologicalization　of　the　industrial　structure　has　the　greatest　influence　on　economic　growth,　followed　by　sophistication　of　the　industrial　structure,　and　rationalization　of　the　industrial　structure　has　the　weakest　influence.　©　2020,　Science　Press　(China).　All　rights　reserved.
