Scale　effect　is　one　of　the　fundamental　problems　in　the　research　of　economy.　The　trend　of　economic　globalization　has　put　forward　higher　requirements　for　macroeconomic　research　on　township　scale.　The　research　on　distribution　characteristics　of　township　gross　domestic　product　(GDP)　can　provide　more　precise　information　to　well　know　spatial　patterns　and　situations　of　Fujian　economy.　The　study　can　also　provide　the　scientific　basis　and　the　decision-making　support　for　optimal　distribution　of　industries　in　Fujian.　The　research　focused　on　the　spatial　difference　of　GDP　data　in　townships　of　Fujian　Province　in　2000,　2005　and　2010　to　reveal　features　of　spatial　autocorrelation　and　aggregation　of　township＇s　economic　development.　The　nighttime　light　data　was　used　to　simulate　township-level　GDP　distribution　by　geographic　information　system　(GIS).　The　results　showed　the　GDP　distribution　had　obvious　positive　correlation　with　spatial　agglomeration　and　unbalanced　regional　economic　development　in　townships　of　Fujian　Province.　The　results　showed　there　is　obvious　positive　correlation　among　GDP　distribution,　spatial　agglomeration　and　unbalanced　regional　economic　development　in　townships　of　Fujian　Province.　Spatial　agglomeration　finally　formed　their　centers　in　Fuzhou,　Xiamen　and　Quanzhou　within　developed　coastal　areas.　From　2000　to　2010,　the　spatial　heterogeneity　and　spatial　agglomeration　decreased,　and　influencing　factors　including　policies　and　geographical　location　were　analyzed　in　this　research.　The　dynamics　of　economic　spatial　pattern　at　township　scale　in　Fujian　showed　that　high　value　clusters　distribute　in　the　coastal　region　as　low　value　clusters　in　inland.　Among　them,　the　economic　development　of　Quanzhou　and　Xiamen　had　a　strong　driving　effect　on　the　surrounding　towns.　This　research　enriched　the　practical　method　to　analyze　the　township＇s　economy　at　provincial　scale.　©　2016　IEEE.
