            <title>Zusammenfassung</title>
            <p>Eine eigenständige Landesentwicklungspolitik der einzelnen Länder in Norddeutschland ist kaum mehr möglich, da Bremens und Hamburgs Metropolfunktionen weit in die Nachbarländer Niedersachsen und Schleswig-Holstein hineinreichen und die Stadtstaaten einige Aufgaben nicht mehr selbständig wahrnehmen können.</p>
            <p>Eine Möglichkeit zur Überwindung dieser Probleme könnte eine Länderneugliederung sein, die das, was “zusammengehört”, planungs- und verwaltungstechnisch zusammenfügen würde. Sie scheint aber sowohl aufgrund verfassungsrechtlicher als auch politischer Hindernisse z.Z. nicht durchsetzbar.</p>
            <p>Alternativ wäre aber eine verstärkte Zusammenarbeit in Planungsgemeinschaften sowohl der betroffenen Länder in Landesaufgaben als auch der Stadtstaaten mit ihrem Umland in Metropol-Umland-Fragen denkbar. Für die Zusammenarbeit der Länder wird eine rechtliche und institutionelle Absicherung der bereits bestehenden Gemeinsamen Kabinettssitzungen, für die Stadt-Umland-Zusammenarbeit die Einrichtung von Regionalverbänden vorgeschlagen, die sich an einigen bundesdeutschen Vorbildern orientieren.</p>

Umgekehrt wurde bei der Festlegung des zentralörtlichen Systems der baden-württembergische Usus, Unterzentren im Regionalplan auszuweisen, auf den bayerischen Regionsteil ausgedehnt.&lt;/bib&gt;</mixed-citation>
