摘要
基于1996—2018年江苏省林业产业的相关数据,分析林业三次产业的演进特征,构建SVAR模型考量林业三次产业在当期、短期和长期的互动影响。结果表明:在当期,江苏省林业三次产业存在即时的结构性联系;短期看,江苏省林业第一产业对第三产业有显著的互动性正向冲击、第二产业对第一产业也有显著的正向冲击;长期看,林业第二产业与第三产业只存在微弱长期的互动性正向冲击;江苏省林业三次产业对自身的冲击具有中长期的差别性正向影响,其中林业第二产业对自身的冲击最大。因此,林业主管部门应重视对林业第一、第二产业中传统优势产业主产区内企业的转型,特别是价值链的核心环节升级,同时加强林业第一产业的资源优势与林业第三产业的跨产业整合。
⑴Background——The growth of the demand for forestry ecological products is an important force to promote the change of the proportion and structure of the forestry primary,secondary and tertiary industries.The composition proportion,service-oriented tendency and interaction effect of the forestry primary,secondary and tertiary industries in Jiangsu Province are important factors to realize the value of ecological products and the high quality development of forestry.⑵Methods——The research hypothesis was put forward on the basis of theoretical analysis.The development of the forestry primary,secondary and tertiary industries in Jiangsu Province was summarized by using the statistical data from 1996 to 2018,the concurrent correlation of the forestry primary,secondary and tertiary industries in Jiangsu Province was analyzed by using the VAR model,then the constraint conditions of structural impact of SVAR model were proposed with reference to the structural dividend theory,and at last the interactive effects of the forestry primary,secondary and tertiary industries in Jiangsu Province both in the short term and long term were analyzed.⑶Results——First,the evolution and development of the forestry primary,secondary and tertiary industries in Jiangsu Province show a significant Kuznets fact and the trend of industrial service.Second,in the current period,the forestry primary,secondary and tertiary industries in Jiangsu Province have immediate structural connections,indicating that the change of external factors such as the increase of demand for ecological products has promoted the process of internal integration of forestry industry.Third,in the short term,the forestry primary industry in Jiangsu Province has a significant mutual positive impact on the forestry tertiary industry,and the forestry secondary industry also has a notable positive impact on the forestry primary industry.Fourth,in the long run,the forestry secondary and tertiary industries in Jiangsu Province have weak positive interaction effect.Fifth,no matter in the short term or in the long term,the forestry primary,secondary and tertiary industries in Jiangsu Province has a substantial positive impact on themselves,among which the forestry secondary industry has the largest positive effect,indicating that there are sub-industries with comparative advantages in the forestry primary,secondary and tertiary industries.⑷Conclusions and Discussions——The forestry authorities in Jiangsu Province should focus on promoting the transformation and upgrading of forestry enterprises in the main production areas of traditional advantageous industries,especially in the value chain.These traditional advantageous industries mainly include flowers,economic forests,wood processing and furniture manufacturing in the forestry primary and secondary industries.The forestry authorities in Jiangsu Province should also consider increasing R&D investment in sub-industries with comparative advantages,or setting up technological transformation projects and strengthening the cross-industry integration of the forestry primary industry and tertiary industry.In the long run,achieving the balance between supply and demand of forestry ecological products will help the mutual benefit and win-win result of the forestry primary and tertiary industries in Jiangsu Province.
