山東省科技金融效率影響因素及區(qū)域差異研究

[摘 要：文章基于DEA模型對2015—2020年山東省16個城市的科技金融效率進行測度，同時構建Tobit模型探究科技金融效率的影響因素，并運用Dagum基尼系數(shù)法探尋了膠東、省會、魯南三大經(jīng)濟圈的科技金融效率區(qū)域差異及其來源。實證結果表明，在5%的顯著性水平下，政府財政科技資金支持程度、產(chǎn)業(yè)升級程度對科技金融效率均具有顯著正向影響，政府干預程度會降低智力資本投入對科技金融效率的影響；近年來山東省科技金融效率區(qū)域差異大體呈下降態(tài)勢，區(qū)域差異主要來源于區(qū)域間差異。研究結果有助于進一步發(fā)揮山東省科技金融效能，進而促進產(chǎn)業(yè)結構升級和區(qū)域協(xié)調發(fā)展。

Abstract：Based on the DEA model，this paper measures the efficiency of technology finance in 16 cities in Shandong province from 2015 to 2020，and constructs the Tobit model to explore the factors affecting the efficiency of technology finance，and uses the Dagum Gini coefficient coefficient method to explore the regional differences and sources of technology finance efficiency in the three economic circles of Jiaodong，the provincial capital，and southern Shandong. The empirical results indicate that at a significant level of 5%，the degree of government financial support for technology，as well as the degree of industrial upgrading，have significance positive impacts on the efficiency of technology finance. The degree of government intervention will reduce the impact of intellectual capital investment on the efficiency of technology finance； in recent years，the regional differences in the efficiency of technology finance in Shandong province have generally shown a downward trend，with regional differences mainly coming from inter regional differences. The research results contribute to further leveraging the efficiency of technology finance in Shandong province，thereby promoting industrial structure upgrading and regional coordinated development.

Key words：technology finance efficiency；adjustment of industrial structure；regional coordinated development；DEA-Tobit；Dagum Gini coefficient

一、引 言

受國際金融危機沖擊，外需持續(xù)緊縮，一定程度上阻礙了山東省經(jīng)濟發(fā)展。從2009年起，山東省積極轉方式、調結構，大力發(fā)展第三產(chǎn)業(yè)、推進“三去一降一補”和培育高新技術企業(yè)，至2017年實施“新舊動能轉換重大工程”，在提升產(chǎn)業(yè)結構、促進經(jīng)濟高質量發(fā)展等方面取得了一系列成效。此外，面對省內“東強西弱”的區(qū)域發(fā)展格局，山東省在2007年啟動了“一體兩翼”發(fā)展戰(zhàn)略，歷經(jīng)重點區(qū)域帶動戰(zhàn)略、發(fā)展西部經(jīng)濟隆起帶和強化濟青煙“三核”引領等階段，至2020年山東省16個城市已形成省會、膠東和魯南三大經(jīng)濟圈的區(qū)域發(fā)展新格局。培育壯大新動能、協(xié)同推進區(qū)域一體化發(fā)展都離不開科學技術的支持，特別是近年來金融資源與科技資源正逐步趨向深度融合（李廣子，2020）［1］。……
